# Creating Augmentations for Brainy
## The BrainyAugmentation Interface
Every augmentation implements this simple yet powerful interface:
```typescript
interface BrainyAugmentation {
// Identification
name: string // Unique name for your augmentation
// Execution control
timing: 'before' | 'after' | 'around' | 'replace' // When to execute
operations: string[] // Which operations to intercept
priority: number // Execution order (higher = first)
// Lifecycle methods
initialize(context: AugmentationContext): Promise<void>
execute<T>(operation: string, params: any, next: () => Promise<T>): Promise<T>
shutdown?(): Promise<void> // Optional cleanup
}
```
## Creating a Storage Augmentation
Storage augmentations are special - they provide the storage backend for Brainy:
```typescript
import { StorageAugmentation } from 'brainy/augmentations'
import { MyCustomStorage } from './my-storage'
export class MyStorageAugmentation extends StorageAugmentation {
private config: MyStorageConfig
constructor(config: MyStorageConfig) {
super()
this.name = 'my-custom-storage'
this.config = config
}
// Called during storage resolution phase
async provideStorage(): Promise<StorageAdapter> {
const storage = new MyCustomStorage(this.config)
this.storageAdapter = storage
return storage
}
// Called during augmentation initialization
protected async onInitialize(): Promise<void> {
await this.storageAdapter!.init()
this.log(`Custom storage initialized`)
}
}
```
### Using Your Storage Augmentation
```typescript
// Register before brain.init()
const brain = new BrainyData()
brain.augmentations.register(new MyStorageAugmentation({
connectionString: 'redis://localhost:6379'
}))
await brain.init() // Will use your storage!
```
## Creating a Feature Augmentation
Here's a complete example of a caching augmentation:
```typescript
import { BaseAugmentation, BrainyAugmentation } from 'brainy/augmentations'
export class CachingAugmentation extends BaseAugmentation {
private cache = new Map<string, any>()
constructor() {
super()
this.name = 'smart-cache'
this.timing = 'around' // Wrap operations
this.operations = ['search'] // Only cache searches
this.priority = 50 // Mid-priority
}
async execute<T>(operation: string, params: any, next: () => Promise<T>): Promise<T> {
if (operation === 'search') {
// Check cache
const cacheKey = JSON.stringify(params)
if (this.cache.has(cacheKey)) {
this.log('Cache hit!')
return this.cache.get(cacheKey)
}
// Execute and cache
const result = await next()
this.cache.set(cacheKey, result)
return result
}
// Pass through other operations
return next()
}
protected async onInitialize(): Promise<void> {
this.log('Cache initialized')
}
async shutdown(): Promise<void> {
this.cache.clear()
await super.shutdown()
}
}
```
## The Four Timing Modes
### 1. `before` - Pre-processing
```typescript
timing = 'before'
async execute(op, params, next) {
// Validate/transform input
const validated = await validate(params)
return next(validated) // Pass modified params
}
```
### 2. `after` - Post-processing
```typescript
timing = 'after'
async execute(op, params, next) {
const result = await next()
// Log, analyze, or modify result
console.log(`Operation ${op} returned:`, result)
return result
}
```
### 3. `around` - Wrapping (middleware)
```typescript
timing = 'around'
async execute(op, params, next) {
console.log('Starting', op)
try {
const result = await next()
console.log('Success', op)
return result
} catch (error) {
console.log('Failed', op, error)
throw error
}
}
```
### 4. `replace` - Complete replacement
```typescript
timing = 'replace'
async execute(op, params, next) {
// Don't call next() - replace entirely!
return myCustomImplementation(params)
}
```
## Operations You Can Intercept
Common operations in Brainy:
- `'storage'` - Storage resolution (special)
- `'add'`, `'addNoun'` - Adding data
- `'search'`, `'similar'` - Searching
- `'update'`, `'delete'` - Modifications
- `'saveNoun'`, `'saveVerb'` - Storage operations
- `'all'` - Intercept everything
## Context Available to Augmentations
```typescript
interface AugmentationContext {
brain: BrainyData // The brain instance
storage: StorageAdapter // Storage backend
config: BrainyDataConfig // Configuration
log: (message: string, level?: 'info' | 'warn' | 'error') => void
}
```
## Real-World Examples
### 1. Redis Storage Augmentation
```typescript
export class RedisStorageAugmentation extends StorageAugmentation {
async provideStorage(): Promise<StorageAdapter> {
return new RedisAdapter({
host: 'localhost',
port: 6379,
// Implement full StorageAdapter interface
})
}
}
```
### 2. Audit Trail Augmentation
```typescript
export class AuditAugmentation extends BaseAugmentation {
timing = 'after'
operations = ['add', 'update', 'delete']
async execute(op, params, next) {
const result = await next()
// Log to audit trail
await this.logAudit({
operation: op,
params,
result,
timestamp: new Date(),
user: this.context.config.currentUser
})
return result
}
}
```
### 3. Rate Limiting Augmentation
```typescript
export class RateLimitAugmentation extends BaseAugmentation {
timing = 'before'
operations = ['search']
private limiter = new RateLimiter({ rps: 100 })
async execute(op, params, next) {
await this.limiter.acquire() // Wait if rate limited
return next()
}
}
```
## Publishing to Brain Cloud Marketplace
Future capability for premium augmentations:
```typescript
// package.json
{
"name": "@brain-cloud/redis-storage",
"brainy": {
"type": "augmentation",
"category": "storage",
"premium": true
}
}
// Users can install via:
// brainy augment install redis-storage
```
## Best Practices
1. **Use BaseAugmentation** - Provides common functionality
2. **Set appropriate priority** - Storage (100), System (80-99), Features (10-50)
3. **Be selective with operations** - Don't use 'all' unless necessary
4. **Handle errors gracefully** - Don't break the chain
5. **Clean up in shutdown()** - Release resources
6. **Log appropriately** - Use context.log() for consistent output
7. **Document your augmentation** - Include examples
## Testing Your Augmentation
```typescript
import { BrainyData } from 'brainy'
import { MyAugmentation } from './my-augmentation'
describe('MyAugmentation', () => {
let brain: BrainyData
beforeEach(async () => {
brain = new BrainyData()
brain.augmentations.register(new MyAugmentation())
await brain.init()
})
afterEach(async () => {
await brain.destroy()
})
it('should enhance searches', async () => {
// Test your augmentation's effect
const results = await brain.search('test')
expect(results).toHaveProperty('enhanced', true)
})
})
```
## Summary
Augmentations are Brainy's extension system. They can:
- Replace storage backends
- Add caching layers
- Implement audit trails
- Add rate limiting
- Sync with external systems
- Transform data
- And much more!
The unified BrainyAugmentation interface makes it easy to create powerful extensions while maintaining consistency across the entire system.

Get up and running with Brainy in 5 minutes!
## Installation
```bash
npm install brainy
```
Or install globally for CLI access:
```bash
npm install -g brainy
```
## Basic Usage
### 1. Initialize Brainy
```javascript
import { BrainyData } from 'brainy'
const brain = new BrainyData()
await brain.init()
```
That's it! No configuration needed. Brainy automatically:
- Downloads embedding models (first time only)
- Sets up storage (in-memory by default)
- Initializes all augmentations
- Configures optimal settings
### 2. Add Your First Data
```javascript
// Add a simple string
await brain.addNoun("JavaScript is a versatile programming language")
// Add with metadata
await brain.addNoun("React is a JavaScript library", {
type: "library",
category: "frontend",
popularity: "high"
})
// Add structured data
await brain.addNoun({
title: "Introduction to TypeScript",
content: "TypeScript adds static typing to JavaScript",
author: "John Doe"
}, {
type: "article",
date: "2024-01-15"
})
```
### 3. Search Your Data
```javascript
// Simple vector search
const results = await brain.search("programming languages")
// Natural language query
const articles = await brain.find("recent articles about TypeScript")
// With metadata filtering
const libraries = await brain.search("JavaScript", {
metadata: { type: "library" },
limit: 5
})
```
## Real-World Examples
### Example 1: Document Search System
```javascript
import { BrainyData } from 'brainy'
import fs from 'fs'
const brain = new BrainyData({
storage: {
type: 'filesystem',
path: './document-index'
}
})
await brain.init()
// Index documents
const documents = [
{ file: 'api-guide.md', content: fs.readFileSync('./docs/api-guide.md', 'utf8') },
{ file: 'tutorial.md', content: fs.readFileSync('./docs/tutorial.md', 'utf8') },
{ file: 'faq.md', content: fs.readFileSync('./docs/faq.md', 'utf8') }
]
for (const doc of documents) {
await brain.addNoun(doc.content, {
filename: doc.file,
type: 'documentation',
indexed: new Date().toISOString()
})
}
// Search documents
const results = await brain.find("how to authenticate users")
console.log(`Found ${results.length} relevant documents:`)
results.forEach(r => console.log(`- ${r.metadata.filename} (${(r.score * 100).toFixed(1)}% match)`))
```
### Example 2: AI Chat with Memory
```javascript
import { BrainyData } from 'brainy'
const brain = new BrainyData()
await brain.init()
class ChatWithMemory {
constructor(brain) {
this.brain = brain
this.sessionId = Date.now().toString()
}
async addMessage(role, content) {
await this.brain.addNoun(content, {
role,
sessionId: this.sessionId,
timestamp: Date.now()
})
}
async getContext(query, limit = 5) {
// Find relevant previous messages
const relevant = await this.brain.find(query, { limit })
return relevant.map(r => ({
role: r.metadata.role,
content: r.content
}))
}
async chat(userMessage) {
// Store user message
await this.addMessage('user', userMessage)
// Get relevant context
const context = await this.getContext(userMessage)
// Your AI logic here (OpenAI, Anthropic, etc.)
const aiResponse = await callYourAI(userMessage, context)
// Store AI response
await this.addMessage('assistant', aiResponse)
return aiResponse
}
}
const chat = new ChatWithMemory(brain)
const response = await chat.chat("What did we discuss about JavaScript?")
```
### Example 3: Semantic Code Search
```javascript
import { BrainyData } from 'brainy'
import { glob } from 'glob'
import fs from 'fs'
const brain = new BrainyData()
await brain.init()
// Index all JavaScript files
const files = await glob('src/**/*.js')
for (const file of files) {
const content = fs.readFileSync(file, 'utf8')
// Extract functions
const functions = content.match(/function\s+(\w+)|const\s+(\w+)\s*=/g) || []
await brain.addNoun(content, {
file,
type: 'code',
language: 'javascript',
functions: functions.map(f => f.replace(/function\s+|const\s+|=/g, '').trim())
})
}
// Search for code
const results = await brain.find("authentication middleware")
console.log('Relevant code files:')
results.forEach(r => {
console.log(`\n${r.metadata.file}:`)
console.log(` Functions: ${r.metadata.functions.join(', ')}`)
console.log(` Relevance: ${(r.score * 100).toFixed(1)}%`)
})
```
## CLI Quick Examples
```bash
# Add data from CLI
brainy add "React is a JavaScript library for building UIs"
# Search
brainy search "JavaScript frameworks"
# Natural language find
brainy find "popular frontend libraries"
# Interactive chat mode
brainy chat
# Import JSON data
brainy import data.json
# Export your brain
brainy export --format json > backup.json
# Check status
brainy status
```
## Advanced Features
### Triple Intelligence Query
```javascript
// Combine vector search + metadata filters + graph relationships
const results = await brain.find({
like: "React", // Vector similarity
where: { // Metadata filtering
type: "library",
popularity: "high",
year: { greaterThan: 2015 }
},
related: { // Graph relationships
to: "JavaScript",
depth: 2
}
}, {
limit: 10,
includeContent: true
})
```
### Pagination
```javascript
// Cursor-based pagination for large result sets
let cursor = null
do {
const results = await brain.search("programming", {
limit: 100,
cursor
})
// Process batch
results.forEach(processResult)
cursor = results.nextCursor
} while (cursor)
```
### Performance Optimization
```javascript
// Pre-filter with metadata for faster searches
const results = await brain.search("*", {
metadata: {
type: "article",
category: "tech",
date: { greaterThan: "2024-01-01" }
},
limit: 1000
})
```
## Storage Options
### Memory (Testing)
```javascript
const brain = new BrainyData() // Default
```
### FileSystem (Development)
```javascript
const brain = new BrainyData({
storage: {
type: 'filesystem',
path: './brain-data'
}
})
```
### Browser (OPFS)
```javascript
const brain = new BrainyData({
storage: { type: 'opfs' }
})
```
### S3 (Production)
```javascript
const brain = new BrainyData({
storage: {
type: 's3',
bucket: 'my-brain-bucket',
region: 'us-east-1',
credentials: {
accessKeyId: process.env.AWS_ACCESS_KEY,
secretAccessKey: process.env.AWS_SECRET_KEY
}
}
})
```
## Tips & Best Practices
1. **Use metadata liberally** - It enables O(log n) filtering
2. **Batch operations when possible** - Use `import()` for bulk data
3. **Enable caching for production** - Automatic with default settings
4. **Use cursor pagination** - For large result sets
5. **Leverage natural language** - `find()` understands context
## Common Patterns
### Similarity Search
```javascript
// Find similar items to an existing one
const item = await brain.getNoun(id)
const similar = await brain.search(item.content, { limit: 5 })
```
### Time-based Queries
```javascript
// Recent items
const recent = await brain.search("*", {
metadata: {
timestamp: { greaterThan: Date.now() - 86400000 } // Last 24 hours
}
})
```
### Category Browsing
```javascript
// Get all items in a category
const category = await brain.search("*", {
metadata: { category: "tutorials" },
limit: 100
})
```
## Troubleshooting
### Models not loading?
```bash
# Clear cache and re-download
rm -rf ~/.cache/brainy
npm run download-models
```
### Slow initialization?
- First run downloads models (~25MB)
- Subsequent runs use cache (< 500ms)
- Use `storage: { type: 'memory' }` for testing
### Out of memory?
- Use filesystem or S3 storage for large datasets
- Enable worker threads (automatic in Node.js)
- Increase Node memory: `NODE_OPTIONS='--max-old-space-size=4096'`

# 🔍 Brainy 2.0 Augmentation System Architecture Audit (REVISED)
**Author**: Senior Architecture Review
**Date**: 2025-08-25
**Status**: 🟡 **WORKING BUT NEEDS MARKETPLACE FEATURES**
## Executive Summary
The augmentation system core execution is WORKING correctly through `AugmentationRegistry`. The system properly executes augmentations before/after operations. However, there's no discovery, installation, or marketplace integration for the brain-cloud registry vision.
---
## 🟢 What's Actually Working
### 1. Execution Mechanism ✅
The `AugmentationRegistry` class properly implements:
```typescript
async execute<T>(operation: string, params: any, mainOperation: () => Promise<T>): Promise<T>
```
- Chains augmentations correctly
- Respects timing (before/after/around)
- Handles operation filtering
- Works with all 27 augmentations
### 2. Registration System ✅
```typescript
brain.augmentations.register(augmentation)
```
- Two-phase initialization works (storage first)
- Context injection works
- Lifecycle management works
### 3. Clean Interface ✅
- 100% of augmentations use `BrainyAugmentation`
- `BaseAugmentation` provides solid foundation
- Proper TypeScript types
### 4. Auto-Configuration ✅
```typescript
new BrainyData({
cache: true, // Auto-registers CacheAugmentation
index: true, // Auto-registers IndexAugmentation
storage: 's3' // Auto-registers S3StorageAugmentation
})
```
---
## 🟡 Missing for Marketplace Vision
### 1. No Package Discovery
**Current**: Manual registration only
```typescript
// Current (manual)
import { NotionSynapse } from './my-custom-synapse'
brain.augmentations.register(new NotionSynapse())
// Needed
await brain.discover('notion') // Search npm/brain-cloud
await brain.install('@soulcraft/notion-synapse')
```
### 2. No Installation Mechanism
**Current**: Must be bundled at build time
**Needed**: Dynamic installation
```typescript
interface AugmentationMarketplace {
search(query: string): Promise<Package[]>
install(packageId: string): Promise<void>
uninstall(packageId: string): Promise<void>
listInstalled(): Promise<Package[]>
checkUpdates(): Promise<Update[]>
}
```
### 3. No Brain Cloud Registry Client
**Current**: No registry concept
**Needed**: Registry integration
```typescript
class BrainCloudRegistry {
private apiUrl = 'https://api.soulcraft.com/brain-cloud'
async search(query: string): Promise<AugmentationPackage[]> {
const response = await fetch(`${this.apiUrl}/augmentations/search?q=${query}`)
return response.json()
}
async getPackage(id: string): Promise<AugmentationPackage> {
const response = await fetch(`${this.apiUrl}/augmentations/${id}`)
return response.json()
}
}
```
### 4. No License Management
**Current**: All augmentations free/bundled
**Needed**: License verification
```typescript
interface LicenseManager {
verify(packageId: string, licenseKey: string): Promise<boolean>
activate(packageId: string, licenseKey: string): Promise<void>
deactivate(packageId: string): Promise<void>
getStatus(packageId: string): Promise<LicenseStatus>
}
```
### 5. No Version Management
**Current**: No versioning
**Needed**: Semver support
```typescript
interface VersionManager {
checkCompatibility(pkg: Package, brainyVersion: string): boolean
resolveConflicts(packages: Package[]): Package[]
upgrade(packageId: string, toVersion: string): Promise<void>
}
```
---
## 📋 Implementation Plan for Marketplace
### Phase 1: Local Package Discovery (1 week)
```typescript
class LocalPackageDiscovery {
async discover(): Promise<Package[]> {
// 1. Search node_modules for brainy augmentations
const packages = await glob('node_modules/@*/package.json')
// 2. Filter for brainy augmentations
return packages.filter(pkg => pkg.brainy?.type === 'augmentation')
}
async load(packageId: string): Promise<BrainyAugmentation> {
// Dynamic import
const module = await import(packageId)
return new module.default()
}
}
```
### Phase 2: NPM Integration (1 week)
```typescript
class NPMRegistry {
async search(query: string): Promise<Package[]> {
// Search npm for packages with brainy keyword
const response = await fetch(
`https://registry.npmjs.org/-/v1/search?text=${query}+keywords:brainy-augmentation`
)
return response.json()
}
async install(packageId: string): Promise<void> {
// Use npm programmatically
await exec(`npm install ${packageId}`)
// Auto-register after install
const aug = await this.load(packageId)
this.brain.augmentations.register(aug)
}
}
```
### Phase 3: Brain Cloud Registry (2 weeks)
```typescript
class BrainCloudMarketplace {
private registry = new BrainCloudRegistry()
private licenses = new LicenseManager()
private installer = new AugmentationInstaller()
async browse(category?: string): Promise<MarketplaceListing[]> {
const packages = await this.registry.list(category)
return packages.map(pkg => ({
...pkg,
installed: this.isInstalled(pkg.id),
licensed: this.isLicensed(pkg.id),
updates: this.hasUpdates(pkg.id)
}))
}
async purchase(packageId: string): Promise<void> {
// 1. Process payment
const license = await this.processPayment(packageId)
// 2. Activate license
await this.licenses.activate(packageId, license)
// 3. Install package
await this.install(packageId)
}
}
```
### Phase 4: Developer Tools (1 week)
```typescript
// CLI for augmentation development
class AugmentationCLI {
async create(name: string): Promise<void> {
// Scaffold new augmentation project
await this.scaffold(name, 'augmentation-template')
}
async test(path: string): Promise<void> {
// Test augmentation locally
const aug = await this.load(path)
await this.runTests(aug)
}
async publish(path: string): Promise<void> {
// Publish to brain-cloud
const pkg = await this.package(path)
await this.registry.publish(pkg)
}
}
```
---

## 💡 Recommendations
### For 2.0 Release
1. **Ship with manual registration** - It works!
2. **Document how to create augmentations** - Critical for adoption
3. **Create 2-3 example augmentations** - Show the patterns
4. **Add basic CLI for testing** - Help developers
### For 2.1 (Q1 2025)
1. **Add NPM discovery** - Find installed augmentations
2. **Dynamic loading** - Import augmentations at runtime
3. **Basic marketplace API** - List available augmentations
4. **Version checking** - Ensure compatibility
### For 3.0 (Q2 2025)
1. **Full marketplace** - Browse, search, install
2. **Payment integration** - Premium augmentations
3. **Developer portal** - Publish augmentations
4. **Enterprise features** - Private registries
---
## ✅ Good News Summary
The augmentation system WORKS! The core architecture is solid:
- Execution mechanism is correct
- Registration works
- Lifecycle management works
- All 27 augmentations function properly
What's missing is the marketplace/discovery layer, which can be added incrementally without breaking the core system. The 2.0 release can ship with manual augmentation registration, and the marketplace features can be added in 2.1+.
**Recommendation: Ship 2.0 with current system, add marketplace in 2.1**

# Augmentations System
## Overview
Brainy's Augmentation System provides a powerful plugin architecture that extends core functionality without modifying the base code. Augmentations can intercept, modify, and enhance any operation in the database.
## Built-in Augmentations
> **Note**: This document shows both available and planned augmentations. Each section is marked with its current status.
### 1. Entity Registry Augmentation ✅ Available
High-performance deduplication for streaming data ingestion.
```typescript
import { EntityRegistryAugmentation } from 'brainy'
const brain = new BrainyData({
augmentations: [
new EntityRegistryAugmentation({
maxCacheSize: 100000, // Track up to 100k unique entities
ttl: 3600000, // 1-hour TTL for cache entries
hashFields: ['id', 'url'] // Fields to use for deduplication
})
]
})
// Automatically prevents duplicate entities
await brain.addNoun("Same content", { id: "123" }) // Added
await brain.addNoun("Same content", { id: "123" }) // Skipped (duplicate)
```
**Benefits:**
- O(1) duplicate detection using bloom filters
- Configurable cache size and TTL
- Custom hash field selection
- Perfect for real-time data streams
### 2. WAL (Write-Ahead Logging) Augmentation ✅ Available

compression: true, // Enable log compression
maxLogSize: 100 * 1024 * 1024 // 100MB max log size
})
]
})
// All operations are now durably logged
await brain.addNoun("Critical data") // Written to WAL before storage
// Recover from crash
const recovered = new BrainyData({
augmentations: [new WALAugmentation({ recover: true })]
})
await recovered.init() // Automatically replays WAL
```
**Features:**
- ACID compliance

temporal: 0.3, // Weight for time proximity
frequency: 0.2, // Weight for interaction frequency
explicit: 0.1 // Weight for explicit ratings
}
})
]
})
// Relationships automatically get intelligent scores
await brain.addVerb(user1, product1, "viewed", { timestamp: Date.now() })
await brain.addVerb(user1, product1, "purchased", { timestamp: Date.now() })
// Automatically calculates relationship strength based on multiple factors
// Query using intelligent scores
const strongRelationships = await brain.find({

augmentations: [
new AutoRegisterEntitiesAugmentation({
types: ['person', 'organization', 'location', 'product'],
confidence: 0.8,
createRelationships: true
})
]
})
// Automatically extracts and registers entities
await brain.addNoun(
"Apple CEO Tim Cook announced the new iPhone 15 in Cupertino",
{ type: "news" }
)
// Automatically creates:
// - Noun: "Tim Cook" (person)
// - Noun: "Apple" (organization)

// - Extracts text and metadata
// - Identifies sections and structure
// - Extracts entities and concepts
// - Generates embeddings per section
// - Creates relationship graph
```
### 2. Database Migration Import
```typescript
// Import from existing databases
await brain.importFromSQL({
connection: 'postgres://localhost/mydb',
tables: {
users: { type: 'person', idField: 'user_id' },
products: { type: 'product', idField: 'sku' },
orders: {
type: 'relationship',
from: 'user_id',
to: 'product_id',
verb: 'purchased'
}
}
})
// Import from MongoDB
await brain.importFromMongo({
uri: 'mongodb://localhost:27017',
database: 'myapp',
collections: {
users: { type: 'person' },
posts: { type: 'content' }
}
})
```
### 3. Stream Import
```typescript
// Import from real-time streams
await brain.importStream({
source: 'kafka://localhost:9092/events',
format: 'json',
transform: (event) => ({
noun: event.data,
metadata: {
type: event.type,
timestamp: event.timestamp
}
}),
deduplication: true
})
```
### 4. Bulk CSV/JSON Import
```typescript
// Import CSV with automatic type detection
await brain.importCSV('./data.csv', {
headers: true,
typeColumn: 'entity_type',
detectRelationships: true,
batchSize: 1000
})
// Import JSON with nested structure handling
await brain.importJSON('./data.json', {
rootPath: '$.entities',
nounPath: '$.content',
metadataPath: '$.properties',
relationshipPath: '$.connections'
})
```
## Creating Custom Augmentations
```typescript
import { Augmentation } from 'brainy'
class CustomAugmentation extends Augmentation {
name = 'CustomAugmentation'
async onInit(brain: BrainyData): Promise<void> {
// Initialize augmentation
console.log('Custom augmentation initialized')
}
async onBeforeAddNoun(content: any, metadata: any): Promise<[any, any]> {
// Modify before adding noun
metadata.processed = true
metadata.timestamp = Date.now()
return [content, metadata]
}
async onAfterAddNoun(id: string, noun: any): Promise<void> {
// React to noun addition
console.log(`Noun ${id} added`)
}
async onBeforeSearch(query: any): Promise<any> {
// Modify search query
query.boost = 'recent'
return query
}
async onAfterSearch(results: any[]): Promise<any[]> {
// Process search results
return results.map(r => ({
...r,
customScore: r.score * 1.5
}))
}
}
// Use custom augmentation
const brain = new BrainyData({
augmentations: [new CustomAugmentation()]
})
```
## Augmentation Lifecycle Hooks
### Available Hooks
```typescript
interface AugmentationHooks {
// Initialization
onInit(brain: BrainyData): Promise<void>
onShutdown(): Promise<void>
// Noun operations
onBeforeAddNoun(content, metadata): Promise<[content, metadata]>
onAfterAddNoun(id, noun): Promise<void>
onBeforeGetNoun(id): Promise<string>
onAfterGetNoun(noun): Promise<any>
onBeforeUpdateNoun(id, updates): Promise<[string, any]>
onAfterUpdateNoun(id, noun): Promise<void>
onBeforeDeleteNoun(id): Promise<string>
onAfterDeleteNoun(id): Promise<void>
// Verb operations
onBeforeAddVerb(source, target, type, metadata): Promise<[any, any, string, any]>
onAfterAddVerb(id, verb): Promise<void>
onBeforeGetVerb(id): Promise<string>
onAfterGetVerb(verb): Promise<any>
// Search operations
onBeforeSearch(query): Promise<any>
onAfterSearch(results): Promise<any[]>
onBeforeFind(query): Promise<any>
onAfterFind(results): Promise<any[]>
// Storage operations
onBeforeSave(data): Promise<any>
onAfterLoad(data): Promise<any>
// Events
onError(error): Promise<void>
onMetric(metric): Promise<void>
}
```
## Augmentation Composition
```typescript
// Combine multiple augmentations
const brain = new BrainyData({
augmentations: [
// Order matters - executed in sequence
new EntityRegistryAugmentation(), // Deduplication first
new AutoRegisterEntitiesAugmentation(), // Entity extraction
new IntelligentVerbScoringAugmentation(), // Scoring
new CompressionAugmentation(), // Compression
new CachingAugmentation(), // Caching
new WALAugmentation(), // Durability
new MonitoringAugmentation() // Monitoring last
]
})
```
## Performance Considerations
1. **Order Matters**: Place filtering augmentations early
2. **Resource Usage**: Monitor memory with many augmentations
3. **Async Operations**: Use parallel processing where possible
4. **Caching**: Enable caching augmentation for read-heavy workloads
## Best Practices
1. **Single Responsibility**: Each augmentation should do one thing well
2. **Non-Blocking**: Avoid blocking operations in hooks
3. **Error Handling**: Always handle errors gracefully
4. **Configuration**: Make augmentations configurable
5. **Documentation**: Document augmentation behavior and options

# Noun-Verb Taxonomy Architecture
## Overview
Brainy 2.0 introduces a revolutionary **Noun-Verb Taxonomy** that models data as entities (nouns) and relationships (verbs), creating a semantic knowledge graph that mirrors how humans naturally think about information.
## Why Noun-Verb?
Traditional databases force you to think in tables, documents, or nodes. Brainy lets you think naturally:
- **Nouns**: Things that exist (people, documents, products, concepts)
- **Verbs**: How things relate (creates, owns, references, similar-to)
This simple mental model scales from basic storage to complex knowledge graphs while remaining intuitive.
## Core Concepts
### Nouns (Entities)
Nouns represent any entity in your system:
```typescript
// Add any entity as a noun
const personId = await brain.addNoun("John Smith, Senior Engineer", {
type: "person",
department: "engineering",
skills: ["TypeScript", "React", "Node.js"]
})
const documentId = await brain.addNoun("Q3 2024 Financial Report", {
type: "document",
category: "financial",
confidential: true,
created: "2024-10-01"
})
const conceptId = await brain.addNoun("Machine Learning", {
type: "concept",
domain: "technology",
complexity: "advanced"
})
```
#### Noun Properties
Every noun automatically gets:
- **Unique ID**: System-generated or custom
- **Vector Embedding**: For semantic similarity
- **Metadata**: Flexible JSON properties
- **Timestamps**: Created/updated tracking
- **Indexing**: Automatic field indexing
### Verbs (Relationships)
Verbs define how nouns relate to each other:
```typescript
// Create relationships between entities
await brain.addVerb(personId, documentId, "authored", {
role: "primary_author",
contribution: "80%"
})
await brain.addVerb(documentId, conceptId, "discusses", {
sections: ["methodology", "results"],
depth: "detailed"
})
await brain.addVerb(personId, conceptId, "expert_in", {
years_experience: 5,
certification: "Advanced ML Certification"
})
```
#### Verb Properties
Every verb includes:
- **Source**: The noun initiating the relationship
- **Target**: The noun receiving the relationship
- **Type**: The relationship type/name
- **Direction**: Directional or bidirectional
- **Metadata**: Relationship-specific data
- **Strength**: Optional relationship weight
## Benefits
### 1. Natural Mental Model
```typescript
// Think naturally about your data
const taskId = await brain.addNoun("Implement payment system")
const userId = await brain.addNoun("Alice Johnson")
const projectId = await brain.addNoun("E-commerce Platform")
// Express relationships clearly
await brain.addVerb(userId, taskId, "assigned_to")
await brain.addVerb(taskId, projectId, "part_of")
await brain.addVerb(userId, projectId, "manages")
```
### 2. Semantic Understanding
The noun-verb model preserves meaning:
```typescript
// The system understands semantic relationships
const results = await brain.find("tasks assigned to Alice")
// Automatically understands: assigned_to verb + Alice noun
const related = await brain.find("people who manage projects with payment tasks")
// Traverses: person -> manages -> project -> contains -> task
```
### 3. Flexible Schema
No rigid schema requirements:
```typescript
// Add any noun type without schema changes
await brain.addNoun("New IoT Sensor", {
type: "device",
protocol: "MQTT",
location: "Building A"
})
// Create new relationship types on the fly
await brain.addVerb(sensorId, buildingId, "monitors", {
metrics: ["temperature", "humidity"],
interval: "5 minutes"
})
```
### 4. Graph Traversal
Navigate relationships naturally:
```typescript
// Find all documents authored by team members
const teamDocs = await brain.find({
connected: {
from: teamId,
through: ["member_of", "authored"],
depth: 2
}
})
// Find similar products purchased by similar users
const recommendations = await brain.find({
connected: {
from: userId,
through: ["similar_to", "purchased"],
depth: 2,
type: "product"
}
})
```
### 5. Temporal Relationships
Track how relationships change over time:
```typescript
// Relationships with temporal data
await brain.addVerb(employeeId, companyId, "worked_at", {
from: "2020-01-01",
to: "2023-12-31",
position: "Senior Developer"
})
await brain.addVerb(employeeId, newCompanyId, "works_at", {
from: "2024-01-01",
position: "Tech Lead"
})
// Query historical relationships
const employment = await brain.find("where did John work in 2022")
```
## Real-World Use Cases
### Knowledge Management
```typescript
// Documents and their relationships
const paperId = await brain.addNoun("Neural Networks Paper", {
type: "research_paper",
year: 2024
})
const authorId = await brain.addNoun("Dr. Sarah Chen", {
type: "researcher"
})
const topicId = await brain.addNoun("Deep Learning", {
type: "topic"
})
// Rich relationship network
await brain.addVerb(authorId, paperId, "authored")
await brain.addVerb(paperId, topicId, "covers")
await brain.addVerb(paperId, otherPaperId, "cites")
await brain.addVerb(authorId, topicId, "researches")
// Query the knowledge graph
const related = await brain.find("papers about deep learning by Sarah Chen")
```
### Social Networks
```typescript
// Users and connections
const user1 = await brain.addNoun("Alice", { type: "user" })
const user2 = await brain.addNoun("Bob", { type: "user" })
const post = await brain.addNoun("Great article on AI!", { type: "post" })
// Social interactions
await brain.addVerb(user1, user2, "follows")
await brain.addVerb(user2, user1, "follows") // Mutual
await brain.addVerb(user1, post, "created")
await brain.addVerb(user2, post, "liked")
await brain.addVerb(user2, post, "shared")
// Find social patterns
const influencers = await brain.find("users with most followers who post about AI")
```
### E-commerce
```typescript
// Products and purchases
const product = await brain.addNoun("Wireless Headphones", {
type: "product",
price: 99.99,
category: "electronics"
})
const customer = await brain.addNoun("Customer #12345", {
type: "customer",
tier: "premium"
})
// Purchase relationships
await brain.addVerb(customer, product, "purchased", {
date: "2024-01-15",
quantity: 1,
price: 99.99
})
await brain.addVerb(customer, product, "reviewed", {
rating: 5,
text: "Excellent sound quality!"
})
// Recommendation queries
const recs = await brain.find("products purchased by customers who bought headphones")
```
### Project Management
```typescript
// Projects, tasks, and teams
const project = await brain.addNoun("Website Redesign", { type: "project" })
const task = await brain.addNoun("Update homepage", { type: "task" })
const developer = await brain.addNoun("Jane Developer", { type: "person" })
const designer = await brain.addNoun("John Designer", { type: "person" })
// Work relationships
await brain.addVerb(task, project, "belongs_to")
await brain.addVerb(developer, task, "assigned_to")
await brain.addVerb(designer, developer, "collaborates_with")
await brain.addVerb(task, otherTask, "depends_on")
// Project queries
const blockers = await brain.find("tasks that depend on incomplete tasks")
const workload = await brain.find("people assigned to multiple active projects")
```
## Advanced Patterns
### Bidirectional Relationships
```typescript
// Some relationships are naturally bidirectional
await brain.addVerb(user1, user2, "friend_of", { bidirectional: true })
// Automatically creates inverse relationship
```
### Weighted Relationships
```typescript
// Add strength/weight to relationships
await brain.addVerb(doc1, doc2, "similar_to", {
similarity_score: 0.95,
algorithm: "cosine"
})
// Use weights in queries
const stronglyRelated = await brain.find({
connected: {
type: "similar_to",
minWeight: 0.8
}
})
```
### Relationship Chains
```typescript
// Follow relationship chains
const results = await brain.find({
connected: {
from: userId,
chain: [
{ type: "owns", to: "company" },
{ type: "produces", to: "product" },
{ type: "uses", to: "technology" }
]
}
})
// Finds: technologies used by products made by companies owned by user
```
### Meta-Relationships
```typescript
// Relationships about relationships
const verbId = await brain.addVerb(user1, user2, "recommends")
await brain.addVerb(user3, verbId, "endorses", {
reason: "Accurate recommendation",
trust_score: 0.9
})
```
## Query Patterns
### Finding Nouns
```typescript
// By type
const people = await brain.find({ where: { type: "person" } })
// By properties
const documents = await brain.find({
where: {
type: "document",
confidential: false,
created: { $gte: "2024-01-01" }
}
})
// By similarity
const similar = await brain.find({
like: "machine learning research",
where: { type: "document" }
})
```
### Finding Verbs
```typescript
// Get all relationships for a noun
const relationships = await brain.getVerbs(nounId)
// Find specific relationship types
const authorships = await brain.find({
verb: {
type: "authored",
from: authorId
}
})
// Find by relationship properties
const recentPurchases = await brain.find({
verb: {
type: "purchased",
where: {
date: { $gte: "2024-01-01" }
}
}
})
```
### Combined Queries
```typescript
// Find nouns through relationships
const results = await brain.find({
// Start with similar documents
like: "AI research",
// That are authored by
connected: {
through: "authored",
// People who work at
where: {
connected: {
to: "Stanford",
type: "works_at"
}
}
}
})
```
## Performance Optimizations
### Noun Indexing
- Automatic vector indexing for similarity
- Field indexing for metadata queries
- Full-text indexing for content search
### Verb Indexing
- Relationship type indexing
- Source/target indexing
- Temporal indexing for time-based queries
### Query Optimization
- Automatic query plan optimization
- Parallel execution of independent operations
- Result caching for repeated queries
## Best Practices
1. **Use Descriptive Types**: Make noun and verb types self-documenting
2. **Rich Metadata**: Include relevant metadata for better querying
3. **Consistent Naming**: Use consistent verb names across your application
4. **Temporal Data**: Include timestamps for time-based analysis
5. **Bidirectional When Appropriate**: Mark symmetric relationships as bidirectional
## Migration from Traditional Models
### From Relational (SQL)
```typescript
// Instead of JOIN queries
// SELECT * FROM users JOIN orders ON users.id = orders.user_id
// Use noun-verb relationships
const userId = await brain.addNoun("User", userData)
const orderId = await brain.addNoun("Order", orderData)
await brain.addVerb(userId, orderId, "placed")
// Query naturally
const userOrders = await brain.find({
connected: { from: userId, type: "placed" }
})
```
### From Document (NoSQL)
```typescript
// Instead of embedded documents
// { user: { orders: [...] } }
// Use explicit relationships
const userId = await brain.addNoun("User", userData)
for (const order of orders) {
const orderId = await brain.addNoun("Order", order)
await brain.addVerb(userId, orderId, "has_order")
}
```
### From Graph Databases
```typescript
// Similar to graph databases but with added benefits:
// 1. Automatic vector embeddings for similarity
// 2. Natural language querying
// 3. Unified with metadata filtering
// Enhanced graph queries
const results = await brain.find("similar users who purchased similar products")
```

### Why This Covers All Knowledge
#### 1. **Mathematical Completeness**
The noun-verb model forms a **complete graph structure** where:
- Any entity can be represented as a noun
- Any relationship can be represented as a verb
- Complex knowledge emerges from simple combinations
#### 2. **Semantic Completeness**
Every piece of human knowledge falls into one of these categories:
- **Entities** (who, what, where) → Nouns
- **Actions** (how, when, why) → Verbs
- **Attributes** (properties) → Metadata
- **Context** (conditions) → Graph structure
#### 3. **Compositional Power**
Simple types combine to represent complex knowledge:
```typescript
// Complex knowledge from simple building blocks
const researchPaper = await brain.addNoun("AI Ethics Study", {
type: "document"
})
const researcher = await brain.addNoun("Dr. Smith", {
type: "person"
})
const institution = await brain.addNoun("MIT", {
type: "organization"
})
const concept = await brain.addNoun("AI Ethics", {
type: "concept"
})
// Rich knowledge graph emerges
await brain.addVerb(researcher, researchPaper, "authors")
await brain.addVerb(researcher, institution, "affiliated")
await brain.addVerb(researchPaper, concept, "explores")
await brain.addVerb(institution, researchPaper, "publishes")
```
#### 4. **Domain Independence**
The same types work across all domains:
**Science:**
```typescript
await brain.addNoun("H2O", { type: "thing", category: "molecule" })
await brain.addNoun("Photosynthesis", { type: "process" })
await brain.addVerb(moleculeId, processId, "participates")
```
**Business:**
```typescript
await brain.addNoun("Q3 Revenue", { type: "metric", value: 10000000 })
await brain.addNoun("Sales Team", { type: "organization" })
await brain.addVerb(teamId, metricId, "achieves")
```
**Social:**
```typescript
await brain.addNoun("John", { type: "person" })
await brain.addNoun("Community Group", { type: "organization" })
await brain.addVerb(personId, groupId, "joins")
```
#### 5. **Temporal Coverage**
Handles all temporal aspects:
```typescript
// Past
await brain.addVerb(personId, companyId, "worked", {
from: "2010", to: "2020"
})
// Present
await brain.addVerb(personId, projectId, "manages", {
since: "2024-01-01"
})
// Future
await brain.addVerb(eventId, venueId, "scheduled", {
date: "2025-06-15"
})
```
#### 6. **Hierarchical Representation**
Supports all levels of abstraction:
```typescript
// Micro level
await brain.addNoun("Electron", { type: "thing", scale: "quantum" })
// Macro level
await brain.addNoun("Solar System", { type: "place", scale: "astronomical" })
// Abstract level
await brain.addNoun("Justice", { type: "concept", domain: "philosophy" })
```
### Extensibility
While the core types cover all knowledge, you can extend with domain-specific subtypes:
```typescript
// Extend person for medical domain
await brain.addNoun("Patient #12345", {
type: "person",
subtype: "patient",
medicalRecord: "MR-12345"
})
// Extend document for legal domain
await brain.addNoun("Contract ABC", {
type: "document",
subtype: "contract",
jurisdiction: "California"
})
// Custom verb for specific domain
await brain.addVerb(lawyerId, contractId, "negotiates", {
verbSubtype: "legal-action",
billableHours: 10
})
```
### Knowledge Completeness Proof
The noun-verb taxonomy achieves **Turing completeness** for knowledge representation:
1. **Storage**: Any data can be stored as nouns
2. **Computation**: Any transformation can be expressed as verbs
3. **State**: Metadata captures all properties
4. **Relations**: Graph structure captures all connections
5. **Time**: Temporal metadata handles all time aspects
6. **Semantics**: Embeddings capture meaning and similarity
This makes Brainy capable of representing:
- Scientific knowledge
- Business intelligence
- Social networks
- Historical records
- Creative content
- Technical documentation
- Personal information
- And any other form of human knowledge
## Conclusion
The Noun-Verb taxonomy in Brainy 2.0 provides a natural, flexible, and powerful way to model any domain. By thinking in terms of entities and their relationships, you can build everything from simple data stores to complex knowledge graphs while maintaining code clarity and query simplicity.

# Architecture Overview
Brainy is a multi-dimensional AI database that combines vector similarity, graph relationships, and metadata filtering into a unified query system. This document provides a comprehensive overview of the system architecture.
## Core Components
### BrainyData (Main Entry Point)
The central orchestrator that manages all subsystems:
- **HNSW Index**: O(log n) vector similarity search
- **Storage System**: Universal storage adapters (FileSystem, S3, OPFS, Memory)
- **Metadata Index**: O(1) field lookups with inverted indexing
- **Augmentation System**: Extensible plugin architecture
- **Triple Intelligence**: Unified query engine
### Triple Intelligence Engine
Brainy's revolutionary feature that unifies three types of search:
- **Vector Search**: Semantic similarity using HNSW indexing
- **Graph Traversal**: Relationship-based queries
- **Field Filtering**: Precise metadata filtering with O(1) performance
```typescript
// Single query combining all three intelligence types
const results = await brain.find({
like: "machine learning papers", // Vector similarity
connected: { to: "research-team", depth: 2 }, // Graph traversal
where: { published: { $gte: "2024-01-01" } } // Metadata filtering
})
```
### Storage Architecture
```
brainy-data/
├── _system/ # System management
│ └── statistics.json
├── nouns/ # Entity data storage
│ └── {uuid}.json
├── metadata/ # Metadata and indexing
│ ├── {uuid}.json
│ ├── __entity_registry__.json
│ └── __metadata_index__*.json
├── verbs/ # Relationship storage
├── wal/ # Write-Ahead Logging
└── locks/ # Concurrent access control
```
### HNSW Index
Hierarchical Navigable Small World index for efficient vector search:
- **Performance**: O(log n) search complexity
- **Memory Efficient**: Product quantization support
- **Scalable**: Handles millions of vectors
- **Persistent**: Serializable to storage
### Metadata Index Manager
High-performance field indexing system:
- **O(1) Lookups**: Inverted index for field→value→IDs mapping
- **Query Support**: equals, anyOf, allOf, range queries
- **Chunked Storage**: Supports massive datasets
- **Auto-indexing**: Automatically maintains indexes on updates
## Performance Characteristics
### Operation Complexity
- **Vector Search**: O(log n) via HNSW
- **Field Filtering**: O(1) via inverted indexes
- **Graph Traversal**: O(V + E) for breadth-first search
- **Add Operation**: O(log n) for index insertion
- **Update Operation**: O(1) for metadata updates
### Memory Usage
- **Base Memory**: ~50MB for core system
- **Per Vector**: ~1KB (384 dimensions × 4 bytes)
- **Index Overhead**: ~20% of vector data
- **Cache Size**: Configurable (default 1000 entries)
### Throughput
- **Writes**: 1000+ ops/second (with batching)
- **Reads**: 10,000+ ops/second
- **Search**: 100+ queries/second (varies by complexity)
## Augmentation System
Brainy's extensible plugin architecture allows for powerful enhancements:
### Core Augmentations
- **WAL (Write-Ahead Logging)**: Durability and crash recovery
- **Entity Registry**: High-speed deduplication for streaming data
- **Batch Processing**: Optimized bulk operations
- **Connection Pool**: Efficient resource management
- **Request Deduplicator**: Prevents duplicate processing
### Creating Custom Augmentations
```typescript
class CustomAugmentation extends BrainyAugmentation {
async onInit(brain: BrainyData): Promise<void> {
// Initialize augmentation
}
async onAdd(item: any, brain: BrainyData): Promise<any> {
// Process item before adding
return item
}
}
```
## Caching Strategy
Multi-layered caching for optimal performance:
- **Search Cache**: LRU cache for query results
- **Metadata Cache**: Field index caching
- **Pattern Cache**: NLP pattern matching cache
- **Entity Cache**: In-memory entity registry
## Integration Points
### Key Objects for Extensions
- `brain.index`: Access HNSW vector index
- `brain.metadataIndex`: Access field indexing
- `brain.storage`: Access storage layer
- `brain.augmentations`: Access augmentation manager
### Event System
```typescript
brain.on('add', (item) => console.log('Item added:', item))
brain.on('search', (query) => console.log('Search performed:', query))
brain.on('error', (error) => console.error('Error:', error))
```
## Best Practices
### When Adding Features

# Storage Architecture
Brainy implements a sophisticated, unified storage system that works across all environments (Node.js, Browser, Edge Workers) with enterprise-grade features like metadata indexing, entity registry, and write-ahead logging.
## Storage Structure
```
brainy-data/
├── _system/ # System management
│ └── statistics.json # Performance metrics and statistics
├── nouns/ # Primary entity storage
│ └── {uuid}.json # Individual entity documents
├── metadata/ # Metadata and indexing system
│ ├── {uuid}.json # Entity metadata
│ ├── __entity_registry__.json # Entity deduplication registry
│ ├── __metadata_field_index__field_{field}.json # Field discovery
│ └── __metadata_index__{field}_{value}_chunk{n}.json # Value indexes
├── verbs/ # Relationship/action storage
│ └── {uuid}.json # Relationship documents
├── wal/ # Write-Ahead Logging
│ └── wal_{timestamp}_{id}.wal # Transaction logs
└── locks/ # Concurrent access control
└── {resource}.lock # Resource locks
```
## Storage Adapters
Brainy provides multiple storage adapters with identical APIs:
### FileSystem Storage (Node.js)
```typescript
const brain = new BrainyData({
storage: {
type: 'filesystem',
path: './data'
}
})
```
- **Use case**: Server applications, CLI tools
- **Performance**: Direct file I/O
- **Persistence**: Permanent on disk
### S3 Compatible Storage
```typescript
const brain = new BrainyData({
storage: {
type: 's3',
bucket: 'my-brainy-data',
region: 'us-east-1',
credentials: {
accessKeyId: process.env.AWS_ACCESS_KEY_ID,
secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY
}
}
})
```
- **Use case**: Distributed applications, cloud deployments
- **Performance**: Network dependent, with intelligent caching
- **Persistence**: Cloud storage durability
### Origin Private File System (Browser)
```typescript
const brain = new BrainyData({
storage: {
type: 'opfs'
}
})
```
- **Use case**: Browser applications, PWAs
- **Performance**: Near-native file system speed
- **Persistence**: Permanent in browser (with quota limits)
### Memory Storage
```typescript
const brain = new BrainyData({
storage: {
type: 'memory'
}
})
```
- **Use case**: Testing, temporary processing
- **Performance**: Fastest possible
- **Persistence**: Volatile (lost on restart)
## Metadata Indexing System
### Field Discovery Index
Tracks all unique values for each field:
```json
// __metadata_field_index__field_category.json
{
"values": {
"technology": 45,
"science": 32,
"business": 28
},
"lastUpdated": 1699564234567
}
```
### Value-Based Indexes
Maps field+value combinations to entity IDs:
```json
// __metadata_index__category_technology_chunk0.json
{
"field": "category",
"value": "technology",
"ids": ["uuid1", "uuid2", "uuid3", ...],
"chunk": 0,
"total": 45
}
```
### Index Chunking
Large indexes automatically chunk for performance:
- **Chunk size**: 10,000 IDs per chunk
- **Auto-splitting**: Transparent to queries
- **Parallel loading**: Chunks load on demand
## Entity Registry
High-performance deduplication system for streaming data:
### Registry Structure
```json
// __entity_registry__.json
{
"mappings": {
"did:plc:alice123": "550e8400-e29b-41d4-a716-446655440000",
"handle:alice.bsky.social": "550e8400-e29b-41d4-a716-446655440000"
},
"stats": {
"totalMappings": 10000,
"lastSync": 1699564234567
}
}
```
### Performance Characteristics
- **Lookup**: O(1) in-memory hash map
- **Persistence**: Configurable (memory/storage/hybrid)
- **Cache**: LRU with configurable TTL
- **Sync**: Periodic or on-demand
## Write-Ahead Logging (WAL)
Ensures durability and enables recovery:
### WAL Entry Format
```json
{
"timestamp": 1699564234567,
"operation": "add",
"data": {
"id": "550e8400-e29b-41d4-a716-446655440000",
"content": "...",
"metadata": {}
},
"checksum": "sha256:..."
}
```
### Recovery Process
1. On startup, check for WAL files
2. Replay operations from last checkpoint
3. Verify checksums for integrity
4. Clean up processed WAL files
## Storage Optimization
### Compression
- **JSON**: Automatic minification
- **Vectors**: Float32 to Uint8 quantization option
- **Indexes**: Binary format for large datasets
### Caching Strategy
```typescript
// Configure caching per storage type
const brain = new BrainyData({
storage: {
type: 'filesystem',
cache: {
enabled: true,
maxSize: 1000, // Maximum cached items
ttl: 300000, // 5 minutes
strategy: 'lru' // Least recently used
}
}
})
```
### Batch Operations
```typescript
// Batch writes for performance
await brain.addBatch([
{ content: "item1", metadata: {} },
{ content: "item2", metadata: {} },
{ content: "item3", metadata: {} }
])
// Single transaction, optimized I/O
```
## Concurrent Access
### Locking Mechanism
```typescript
// Automatic locking for write operations
await brain.storage.withLock('resource-id', async () => {
// Exclusive access to resource
await brain.storage.saveNoun(id, data)
})
```
### Read-Write Separation
- **Reads**: Non-blocking, parallel
- **Writes**: Serialized with locks
- **Hybrid**: Read-heavy optimization
## Migration and Backup
### Export Data
```typescript
// Export entire database
const backup = await brain.export({
format: 'json',
includeVectors: true,
includeIndexes: false
})
```
### Import Data
```typescript
// Import from backup
await brain.import(backup, {
mode: 'merge', // or 'replace'
validateSchema: true
})
```
### Storage Migration
```typescript
// Migrate between storage types
const oldBrain = new BrainyData({ storage: { type: 'filesystem' } })
const newBrain = new BrainyData({ storage: { type: 's3' } })
await oldBrain.init()
await newBrain.init()
// Transfer all data
const data = await oldBrain.export()
await newBrain.import(data)
```
## Performance Tuning
### Storage-Specific Optimizations
#### FileSystem
- **Directory sharding**: Split files across subdirectories
- **Async I/O**: Non-blocking file operations
- **Buffer pooling**: Reuse buffers for efficiency
#### S3
- **Multipart uploads**: For large objects
- **Request batching**: Combine small operations
- **CDN integration**: Edge caching for reads
#### OPFS
- **Quota management**: Monitor and request increases
- **Worker offloading**: Heavy operations in workers
- **Transaction batching**: Group operations
### Monitoring
```typescript
// Get storage statistics
const stats = await brain.storage.getStatistics()
console.log(stats)
// {
// totalSize: 1048576,
// entityCount: 1000,
// indexSize: 204800,
// walSize: 10240,
// cacheHitRate: 0.85
// }
```
## Best Practices
### Choose the Right Adapter
1. **Development**: Memory or FileSystem
2. **Production Server**: FileSystem or S3
3. **Browser Apps**: OPFS or Memory
4. **Distributed**: S3 with caching
### Optimize for Your Use Case
1. **Read-heavy**: Enable aggressive caching
2. **Write-heavy**: Use WAL and batching
3. **Real-time**: Memory with periodic persistence
4. **Archival**: S3 with compression
### Monitor and Maintain
1. Regular statistics collection
2. WAL cleanup scheduling
3. Index optimization
4. Cache tuning based on hit rates

# Triple Intelligence System
The Triple Intelligence System is Brainy's revolutionary query engine that unifies vector similarity, graph relationships, and metadata filtering into a single, optimized query interface.
## Overview
Traditional databases force you to choose between vector search, graph traversal, OR metadata filtering. Brainy combines all three intelligences into one magical API that automatically optimizes execution for maximum performance.
## Query Interface
### Unified Query Structure
```typescript
interface TripleQuery {
// Vector/Semantic search
like?: string | Vector | any
similar?: string | Vector | any
// Graph/Relationship search
connected?: {
to?: string | string[]
from?: string | string[]
type?: string | string[]
depth?: number
direction?: 'in' | 'out' | 'both'
}
// Field/Attribute search
where?: Record<string, any>
// Advanced options
limit?: number
boost?: 'recent' | 'popular' | 'verified' | string
explain?: boolean
threshold?: number
}
```
### Example Queries
#### Natural Language Queries with find()
```typescript
// Brainy understands natural language and extracts intent
const results = await brain.find("research papers about neural networks from 2023")
// Automatically interprets: document type, topic, time range
// Complex temporal and numeric queries
const reports = await brain.find("quarterly reports from Q3 2024 with revenue over 10M")
// Automatically extracts: report type, date range, numeric filters
// Multi-condition natural language
const articles = await brain.find("verified articles by John Smith about machine learning published this year")
// Automatically identifies: author, topic, verification status, time range
```
#### Simple Vector Search
```typescript
const results = await brain.search("machine learning concepts")
```
#### Combined Intelligence Query
```typescript
const results = await brain.find({
like: "neural networks",
where: {
category: "research",
year: { $gte: 2023 }
},
connected: {
to: "deep-learning-team",
depth: 2
},
limit: 20
})
```
## Query Optimization
### Automatic Plan Generation
The Triple Intelligence engine analyzes each query to create an optimal execution plan:
1. **Selectivity Analysis**: Identifies the most selective filters
2. **Cost Estimation**: Estimates computational cost for each operation
3. **Strategy Selection**: Chooses between parallel or progressive execution
4. **Plan Caching**: Caches successful plans for similar queries
### Execution Strategies
#### Parallel Execution
All three search types execute simultaneously:
- **Best for**: Balanced queries with multiple signals
- **Performance**: Maximum speed through parallelization
- **Use case**: Complex queries needing all intelligence types
```typescript
// Parallel execution for balanced query
const results = await brain.find({
like: "AI research", // ~1000 potential matches
where: { type: "paper" }, // ~500 potential matches
connected: { to: "stanford" } // ~200 potential matches
})
// All three execute in parallel, results fused
```
#### Progressive Filtering
Operations chain for maximum efficiency:
- **Best for**: Queries with highly selective filters
- **Performance**: Reduces search space at each step
- **Use case**: Large datasets with specific criteria
```typescript
// Progressive execution for selective query
const results = await brain.find({
where: { userId: "user123" }, // Very selective (1-10 matches)
like: "recent posts", // Applied to filtered set
limit: 5
})
// Metadata filter first, then vector search on results
```
## Fusion Ranking
### Score Combination
When multiple intelligence types return results, scores are intelligently combined:
```typescript
fusionScore = (
vectorScore * vectorWeight + // Semantic relevance (0.4)
graphScore * graphWeight + // Relationship strength (0.3)
fieldScore * fieldWeight // Exact match confidence (0.3)
) / totalWeight
```
### Adaptive Weights
Weights adjust based on query characteristics:
- **Text-heavy query**: Higher vector weight
- **Relationship query**: Higher graph weight
- **Specific filters**: Higher field weight
## Natural Language Processing
### Pattern Recognition
Brainy includes 220+ embedded patterns for natural language understanding:
```typescript
// Natural language automatically parsed
const results = await brain.search(
"show me recent AI papers from Stanford published this year"
)
// Automatically converts to:
// {
// like: "AI papers",
// where: {
// institution: "Stanford",
// published: { $gte: "2024-01-01" }
// }
// }
```
### Intent Detection
The NLP processor identifies query intent:
- **Informational**: "what is", "how does"
- **Navigational**: "find", "show me"
- **Transactional**: "create", "update"
- **Analytical**: "compare", "analyze"
## Performance Optimization
### Query Plan Caching
Successful execution plans are cached:
```typescript
// First query: 50ms (plan generation + execution)
await brain.search("machine learning papers")
// Subsequent similar queries: 10ms (cached plan)
await brain.search("deep learning papers")
```
### Self-Optimization
Brainy uses itself to optimize queries:
- Query patterns stored in separate brain instance
- Execution times tracked and analyzed
- Plans automatically improved based on performance
### Index Utilization
Triple Intelligence leverages all available indexes:
- **HNSW Index**: For vector similarity
- **Metadata Index**: For metadata filtering
- **Graph Index**: For relationship traversal
## Advanced Features
### Explain Mode
Understand how your query was executed:
```typescript
const results = await brain.find({
like: "quantum computing",
where: { category: "research" },
explain: true
})
console.log(results[0].explanation)
// {
// plan: "field-first-progressive",
// timing: {
// fieldFilter: 2,
// vectorSearch: 8,
// fusion: 1
// },
// selectivity: {
// field: 0.1,
// vector: 0.3
// }
// }
```
### Boosting
Apply custom ranking boosts:
```typescript
const results = await brain.find({
like: "news articles",
boost: 'recent', // Boost recent items
where: { verified: true }
})
```
### Threshold Control
Set minimum similarity thresholds:
```typescript
const results = await brain.find({
like: "exact match needed",
threshold: 0.9, // Only very similar results
limit: 10
})
```
## Best Practices
### Query Design
1. **Start specific**: Use selective filters when possible
2. **Combine intelligently**: Don't force all three types if not needed
3. **Use limits**: Always specify reasonable result limits
4. **Cache results**: For repeated queries, cache at application level
### Performance Tips
1. **Index first**: Ensure fields used in `where` clauses are indexed
2. **Batch operations**: Use batch methods for bulk queries
3. **Monitor plans**: Use explain mode to understand performance
4. **Optimize patterns**: Train custom patterns for your domain
### Common Patterns
#### Semantic Search with Filtering
```typescript
// Find similar content with constraints
const results = await brain.find({
like: query,
where: {
status: 'published',
language: 'en'
}
})
```
#### Related Items Discovery
```typescript
// Find items related to a specific item
const results = await brain.find({
connected: {
to: itemId,
depth: 2,
type: 'similar'
},
limit: 20
})
```
#### Time-based Queries
```typescript
// Recent items matching criteria
const results = await brain.find({
where: {
timestamp: { $gte: Date.now() - 86400000 }
},
like: "trending topics",
boost: 'recent'
})
```
## Natural Language Processing
The `find()` method includes advanced NLP capabilities powered by 220+ embedded patterns that understand natural language queries.
### Supported Query Types
```typescript
// Temporal queries
await brain.find("documents from last week")
await brain.find("reports created yesterday")
await brain.find("articles published in Q3 2024")
await brain.find("data from January to March")
// Numeric filters
await brain.find("products with price under $100")
await brain.find("articles with more than 1000 views")
await brain.find("reports showing revenue over 10M")
// Combined conditions
await brain.find("verified research papers about AI from 2024 with high citations")
await brain.find("recent customer reviews with rating above 4 stars")
await brain.find("blog posts by John Smith about machine learning published this month")
// Relationship queries
await brain.find("documents related to project X")
await brain.find("people who work at TechCorp")
await brain.find("products similar to iPhone")
```
### How It Works
1. **Intent Detection**: Identifies what the user is looking for
2. **Entity Extraction**: Extracts names, dates, numbers, categories
3. **Temporal Parsing**: Converts "last week", "Q3 2024" to date ranges
4. **Filter Generation**: Creates appropriate where clauses
5. **Query Fusion**: Combines NLP understanding with vector search
### Pattern Coverage
Brainy includes 220+ pre-computed patterns covering:
- **Temporal**: 40+ patterns for dates and time ranges
- **Numeric**: 30+ patterns for comparisons and ranges
- **Relationships**: 25+ patterns for connections
- **Actions**: 35+ patterns for verbs and intents
- **Entities**: 40+ patterns for people, places, things
- **Domain-specific**: 50+ patterns for tech, business, social

# Zero Configuration & Auto-Adaptation
> **Current Status**: Basic zero-config is fully functional. Advanced auto-adaptation features are in development.
## Overview
Brainy is designed with **"Zero Config by Default, Infinite Tunability"** philosophy. It automatically detects your environment, adapts to available resources, learns from usage patterns, and optimizes itself for your specific workload—all without any configuration.
## Zero Configuration Magic
### Instant Start
```typescript
import { BrainyData } from 'brainy'
// That's it. No config needed.
const brain = new BrainyData()
await brain.init()
// Brainy automatically:
// ✓ Detects environment (Node.js, Browser, Edge, Deno)
// ✓ Chooses optimal storage (FileSystem, OPFS, Memory)
// ✓ Downloads required models (if needed)
// ✓ Configures vector dimensions (384 optimal)
// ✓ Sets up indexing strategies
// ✓ Enables appropriate augmentations
// ✓ Configures caching layers
// ✓ Optimizes for your hardware
```
### Environment Detection ✅ Available
Brainy automatically detects and adapts to your runtime:
```typescript
// Brainy's environment detection
const environment = {
// Runtime detection
isNode: typeof process !== 'undefined',
isBrowser: typeof window !== 'undefined',
isDeno: typeof Deno !== 'undefined',
isEdge: typeof EdgeRuntime !== 'undefined',
isWebWorker: typeof WorkerGlobalScope !== 'undefined',
// Capability detection
hasFileSystem: /* auto-detected */,
hasIndexedDB: /* auto-detected */,
hasOPFS: /* auto-detected */,
hasWebGPU: /* auto-detected */,
hasWASM: /* auto-detected */,
// Resource detection
cpuCores: /* auto-detected */,
memory: /* auto-detected */,
storage: /* auto-detected */
}
```
## Auto-Adaptive Storage ✅ Available
> **Current**: Brainy automatically selects the best storage adapter for your environment.
### Storage Selection Logic
```typescript
// Brainy's intelligent storage selection
async function autoSelectStorage() {
// Server environments
if (environment.isNode) {
if (await hasWritePermission('./data')) {
return 'filesystem' // Best for servers
} else if (process.env.S3_BUCKET) {
return 's3' // Cloud deployment
} else {
return 'memory' // Fallback for restricted environments
}
}
// Browser environments
if (environment.isBrowser) {
if (await navigator.storage.estimate() > 1GB) {
return 'opfs' // Best for modern browsers
} else if (indexedDB) {
return 'indexeddb' // Fallback for older browsers
} else {
return 'memory' // In-memory for restricted contexts
}
}
// Edge environments
if (environment.isEdge) {
return 'kv' // Use edge KV stores (Cloudflare, Vercel)
}
}
```
### Storage Migration
Brainy seamlessly migrates between storage types:
```typescript
// Start with memory storage (development)
const brain = new BrainyData() // Auto-selects memory
// Later, migrate to production storage
await brain.migrate({
to: 'filesystem',
path: './production-data'
})
// All data seamlessly transferred
```
## Learning & Optimization 🚧 Coming Soon
> **Note**: These features are planned for Q2 2025. Currently, Brainy uses static optimizations.
### Query Pattern Learning 🚧 Planned
Brainy learns from your query patterns and optimizes accordingly:
```typescript
// Brainy observes query patterns
class QueryPatternLearner {
analyze(queries: Query[]) {
return {
// Frequency analysis
mostCommonFields: this.getTopFields(queries),
avgResultSize: this.getAvgSize(queries),
temporalPatterns: this.getTimePatterns(queries),
// Relationship analysis
commonTraversals: this.getGraphPatterns(queries),
typicalDepth: this.getAvgDepth(queries),
// Performance analysis
slowQueries: this.getSlowQueries(queries),
cacheability: this.getCacheability(queries)
}
}
}
// Automatic optimizations based on learning:
// - Creates indexes for frequently queried fields
// - Pre-computes common graph traversals
// - Adjusts cache sizes based on working set
// - Optimizes vector search parameters
```
### Auto-Indexing 🚧 Planned
Brainy automatically creates indexes based on usage:
```typescript
// No manual index configuration needed
await brain.find({ where: { category: "tech" } }) // First query
// Brainy notices 'category' field usage
await brain.find({ where: { category: "science" } }) // Second query
// Pattern detected - auto-creates category index
await brain.find({ where: { category: "tech" } }) // Third query
// Now using index - 100x faster!
```
### Adaptive Caching 🚧 Planned
Cache strategies adapt to your access patterns:
```typescript
class AdaptiveCache {
async adapt(metrics: AccessMetrics) {
if (metrics.hitRate < 0.3) {
// Low hit rate - switch strategy
this.strategy = 'lfu' // Least Frequently Used
} else if (metrics.workingSet > this.size) {
// Working set too large - increase size
this.size = Math.min(metrics.workingSet * 1.5, maxMemory)
} else if (metrics.temporalLocality > 0.8) {
// High temporal locality - use time-based eviction
this.strategy = 'ttl'
this.ttl = metrics.avgAccessInterval * 2
}
}
}
```
## Performance Auto-Scaling 🚧 Coming Soon
### Dynamic Batch Sizing
Brainy adjusts batch sizes based on system load:
```typescript
class DynamicBatcher {
calculateOptimalBatch() {
const cpuUsage = process.cpuUsage()
const memoryUsage = process.memoryUsage()
if (cpuUsage < 30 && memoryUsage < 50) {
return 1000 // System idle - large batches
} else if (cpuUsage < 60 && memoryUsage < 70) {
return 100 // Moderate load - medium batches
} else {
return 10 // High load - small batches
}
}
}
// Automatically applied during bulk operations
for (const item of millionItems) {
await brain.addNoun(item) // Internally batched optimally
}
```
### Memory Management
Automatic memory pressure handling:
```typescript
class MemoryManager {
async handlePressure() {
const usage = process.memoryUsage()
const available = os.freemem()
if (available < 100 * 1024 * 1024) { // Less than 100MB free
// Emergency mode
await this.flushCaches()
await this.compactIndexes()
await this.offloadToDisk()
} else if (usage.heapUsed / usage.heapTotal > 0.9) {
// Preventive mode
await this.reduceCacheSizes()
await this.pauseBackgroundTasks()
}
}
}
```
### Connection Pooling
Automatic connection management for storage backends:
```typescript
class ConnectionPool {
async getOptimalPoolSize() {
// Adapts based on workload
const metrics = await this.getMetrics()
if (metrics.waitTime > 100) {
// Queries waiting - increase pool
this.size = Math.min(this.size * 1.5, this.maxSize)
} else if (metrics.idleConnections > this.size * 0.5) {
// Too many idle - decrease pool
this.size = Math.max(this.size * 0.7, this.minSize)
}
return this.size
}
}
```
## Model Auto-Selection
### Embedding Model Selection
Brainy chooses the best embedding model for your use case:
```typescript
async function autoSelectModel(data: Sample[]) {
const analysis = {
languages: detectLanguages(data),
domainSpecific: detectDomain(data),
averageLength: getAvgLength(data),
requiresMultilingual: languages.length > 1
}
if (analysis.requiresMultilingual) {
return 'multilingual-e5-base' // Handles 100+ languages
} else if (analysis.domainSpecific === 'code') {
return 'codebert-base' // Optimized for code
} else if (analysis.averageLength > 512) {
return 'all-mpnet-base-v2' // Better for long text
} else {
return 'all-MiniLM-L6-v2' // Fast and efficient default
}
}
```
### Model Downloading
Models are automatically downloaded when needed:
```typescript
// First use - model auto-downloads
const brain = new BrainyData()
await brain.init() // Downloads model if not cached
// Intelligent model caching
const modelCache = {
location: process.env.MODEL_CACHE || '~/.brainy/models',
maxSize: 5 * 1024 * 1024 * 1024, // 5GB max
strategy: 'lru', // Least recently used eviction
// CDN selection based on location
cdn: await selectFastestCDN([
'https://cdn.brainy.io',
'https://brainy.b-cdn.net',
'https://models.huggingface.co'
])
}
```
## Workload Detection
### Pattern Recognition
Brainy identifies your workload type and optimizes:
```typescript
enum WorkloadType {
OLTP = 'oltp', // Many small transactions
OLAP = 'olap', // Analytical queries
STREAMING = 'streaming', // Real-time ingestion
BATCH = 'batch', // Bulk processing
HYBRID = 'hybrid' // Mixed workload
}
class WorkloadDetector {
detect(metrics: OperationMetrics): WorkloadType {
if (metrics.writesPerSecond > 1000 && metrics.avgWriteSize < 1024) {
return WorkloadType.STREAMING
} else if (metrics.avgQueryComplexity > 0.8 && metrics.avgResultSize > 10000) {
return WorkloadType.OLAP
} else if (metrics.batchOperations > metrics.singleOperations) {
return WorkloadType.BATCH
} else if (metrics.writeReadRatio > 0.3 && metrics.writeReadRatio < 0.7) {
return WorkloadType.HYBRID
} else {
return WorkloadType.OLTP
}
}
}
```
### Optimization Strategies
Different optimizations for different workloads:
```typescript
class WorkloadOptimizer {
optimize(workload: WorkloadType) {
switch (workload) {
case WorkloadType.STREAMING:
return {
entityRegistry: true, // Deduplication
batchSize: 1000,
walEnabled: true,
cacheSize: 'small',
indexStrategy: 'lazy'
}
case WorkloadType.OLAP:
return {
entityRegistry: false,
batchSize: 10000,
walEnabled: false,
cacheSize: 'large',
indexStrategy: 'eager',
parallelQueries: true
}
case WorkloadType.BATCH:
return {
entityRegistry: false,
batchSize: 50000,
walEnabled: false,
cacheSize: 'minimal',
indexStrategy: 'deferred'
}
default:
return this.defaultConfig
}
}
}
```
## Hardware Adaptation 🚧 Coming Soon
> **Note**: GPU acceleration and hardware optimization planned for Q3 2025.
### CPU Optimization
Adapts to available CPU resources:
```typescript
class CPUAdapter {
async optimize() {
const cores = os.cpus().length
const type = os.cpus()[0].model
// Parallel processing based on cores
this.parallelism = Math.max(1, cores - 1) // Leave one core free
// SIMD detection for vector operations
if (type.includes('Intel') || type.includes('AMD')) {
this.enableSIMD = await checkSIMDSupport()
}
// Thread pool sizing
this.threadPoolSize = cores * 2 // Optimal for I/O bound
// Vector search optimization
if (cores >= 8) {
this.hnswConstruction = 200 // Higher quality index
this.hnswSearch = 100 // More accurate search
} else {
this.hnswConstruction = 100 // Balanced
this.hnswSearch = 50 // Faster search
}
}
}
```
### Memory Adaptation
Intelligent memory allocation:
```typescript
class MemoryAdapter {
async configure() {
const totalMemory = os.totalmem()
const availableMemory = os.freemem()
// Allocate based on available memory
const allocation = {
cache: Math.min(availableMemory * 0.25, 2 * GB),
vectors: Math.min(availableMemory * 0.30, 4 * GB),
indexes: Math.min(availableMemory * 0.20, 2 * GB),
working: Math.min(availableMemory * 0.25, 2 * GB)
}
// Adjust for low memory systems
if (totalMemory < 4 * GB) {
allocation.cache *= 0.5
allocation.vectors *= 0.7
this.enableSwapping = true
}
return allocation
}
}
```
### GPU Acceleration
Automatic GPU detection and utilization:
```typescript
class GPUAdapter {
async detect() {
// WebGPU in browsers
if (navigator?.gpu) {
const adapter = await navigator.gpu.requestAdapter()
return {
available: true,
type: 'webgpu',
memory: adapter.limits.maxBufferSize,
compute: adapter.limits.maxComputeWorkgroupsPerDimension
}
}
// CUDA in Node.js
if (process.platform === 'linux' || process.platform === 'win32') {
const hasCuda = await checkCudaSupport()
if (hasCuda) {
return {
available: true,
type: 'cuda',
memory: await getCudaMemory(),
compute: await getCudaCores()
}
}
}
return { available: false }
}
async optimize(gpu: GPUInfo) {
if (gpu.available) {
// Offload vector operations to GPU
this.vectorOps = 'gpu'
this.embeddingGeneration = 'gpu'
this.matrixMultiplication = 'gpu'
// Larger batch sizes for GPU
this.batchSize = gpu.memory > 8 * GB ? 10000 : 1000
}
}
}
```
## Network Adaptation
### Bandwidth Detection
Optimizes for available network bandwidth:
```typescript
class NetworkAdapter {
async measureBandwidth() {
const testSize = 1 * MB
const start = Date.now()
await this.transfer(testSize)
const duration = Date.now() - start
const bandwidth = (testSize / duration) * 1000 // bytes/sec
if (bandwidth < 1 * MB) {
// Low bandwidth - optimize
this.compression = 'aggressive'
this.batchTransfers = true
this.cacheRemote = true
} else if (bandwidth > 100 * MB) {
// High bandwidth
this.compression = 'minimal'
this.parallelTransfers = true
}
}
}
```
### Latency Optimization
Adapts to network latency:
```typescript
class LatencyOptimizer {
async optimize() {
const latency = await this.measureLatency()
if (latency > 100) { // High latency
// Batch operations
this.minBatchSize = 100
// Aggressive prefetching
this.prefetchDepth = 3
// Local caching
this.cacheStrategy = 'aggressive'
// Connection pooling
this.connectionPool = Math.min(latency / 10, 50)
}
}
}
```
## Cloud Provider Detection 🚧 Coming Soon
> **Note**: Cloud provider auto-detection planned for Q3 2025.
### Automatic Cloud Optimization
Detects and optimizes for cloud providers:
```typescript
class CloudDetector {
async detect() {
// AWS Detection
if (process.env.AWS_REGION || await canReachMetadata('169.254.169.254')) {
return {
provider: 'aws',
instance: await getEC2InstanceType(),
region: process.env.AWS_REGION,
services: {
storage: 's3',
cache: 'elasticache',
compute: 'lambda'
}
}
}
// Google Cloud Detection
if (process.env.GOOGLE_CLOUD_PROJECT || await canReachMetadata('metadata.google.internal')) {
return {
provider: 'gcp',
instance: await getGCEInstanceType(),
region: process.env.GOOGLE_CLOUD_REGION,
services: {
storage: 'gcs',
cache: 'memorystore',
compute: 'cloud-run'
}
}
}
// Vercel Edge Detection
if (process.env.VERCEL) {
return {
provider: 'vercel',
region: process.env.VERCEL_REGION,
services: {
storage: 'vercel-kv',
cache: 'edge-config',
compute: 'edge-runtime'
}
}
}
}
}
```
## Development vs Production
### Automatic Environment Detection
```typescript
class EnvironmentDetector {
detect() {
const indicators = {
// Development indicators
isDevelopment:
process.env.NODE_ENV === 'development' ||
process.env.DEBUG ||
process.argv.includes('--dev') ||
isLocalhost() ||
hasDevTools(),
// Test indicators
isTest:
process.env.NODE_ENV === 'test' ||
process.env.CI ||
isTestRunner(),
// Production indicators
isProduction:
process.env.NODE_ENV === 'production' ||
process.env.VERCEL ||
process.env.NETLIFY ||
!isLocalhost()
}
return indicators
}
}
// Different defaults for different environments
const config = environment.isProduction ? {
storage: 'filesystem',
wal: true,
monitoring: true,
compression: true,
caching: 'aggressive'
} : {
storage: 'memory',
wal: false,
monitoring: false,
compression: false,
caching: 'minimal'
}
```
## Error Recovery
### Automatic Fallbacks
Brainy automatically recovers from errors:
```typescript
class AutoRecovery {
async handleStorageFailure() {
try {
await this.primaryStorage.write(data)
} catch (error) {
console.warn('Primary storage failed, trying fallback')
// Try secondary storage
if (this.secondaryStorage) {
await this.secondaryStorage.write(data)
} else {
// Fall back to memory
await this.memoryStorage.write(data)
// Schedule retry
this.scheduleRetry(data)
}
}
}
async handleModelFailure() {
try {
return await this.primaryModel.embed(text)
} catch (error) {
// Fall back to simpler model
return await this.fallbackModel.embed(text)
}
}
}
```
## Configuration Override
While zero-config is default, you can override when needed:
```typescript
// Explicit configuration when needed
const brain = new BrainyData({
// Override auto-detection
storage: {
type: 'filesystem',
path: '/custom/path'
},
// Override auto-optimization
optimization: {
autoIndex: false,
autoCache: false,
autoBatch: false
},
// Override auto-scaling
scaling: {
maxMemory: 2 * GB,
maxConnections: 100,
maxBatchSize: 1000
}
})
```
## Monitoring Auto-Adaptation
Brainy provides visibility into its auto-adaptation:
```typescript
brain.on('adaptation', (event) => {
console.log(`Brainy adapted: ${event.type}`)
console.log(`Reason: ${event.reason}`)
console.log(`Before: ${JSON.stringify(event.before)}`)
console.log(`After: ${JSON.stringify(event.after)}`)
})
// Example events:
// - Index created for frequently queried field
// - Cache strategy changed due to low hit rate
// - Batch size increased due to high throughput
// - Storage migrated due to space constraints
// - Model switched due to multilingual content
```
## Conclusion
Brainy's zero-configuration and auto-adaptation capabilities mean you can focus on your application logic while Brainy handles:
- Environment detection and optimization
- Storage selection and migration
- Performance tuning and scaling
- Resource management
- Error recovery
- Workload optimization
Just create a Brainy instance and start using it. Brainy will learn, adapt, and optimize itself for your specific use case—no configuration required.

# 🔌 Brainy 2.0 Augmentations Complete Reference
> **All 27 augmentations that power Brainy's extensibility - with locations, usage, and examples**
## Quick Start
```typescript
import { BrainyData } from '@soulcraft/brainy'
const brain = new BrainyData({
// Augmentations auto-configure based on environment
storage: 'auto', // Storage augmentation
cache: true, // Cache augmentation
index: true // Index augmentation
})
await brain.init() // Augmentations initialize automatically
```
## Core Concepts
### What are Augmentations?
Augmentations are modular extensions that add functionality to Brainy without cluttering the core API. They follow a unified interface and can be:
- **Auto-enabled**: Based on configuration (cache, index, storage)
- **Manually registered**: For custom functionality
- **Chained**: Multiple augmentations work together seamlessly
### Augmentation Lifecycle
1. **Registration**: Augmentations register before init()
2. **Initialization**: Two-phase init (storage first, then others)
3. **Execution**: Hook into operations (before/after/both)
4. **Shutdown**: Clean teardown on brain.shutdown()

index: true, // Index augmentation
wal: true, // WAL augmentation
metrics: true // Metrics augmentation
})
```
### Manual Registration
```typescript
const brain = new BrainyData()
// Register before init()
const customAug = new MyCustomAugmentation()
await brain.registerAugmentation(customAug)
await brain.init()
```
### Creating Custom Augmentations
```typescript
import { BaseAugmentation } from '@soulcraft/brainy'
class MyAugmentation extends BaseAugmentation {
readonly name = 'my-augmentation'
readonly timing = 'after' // before | after | both
readonly operations = ['addNoun', 'search'] // Which ops to hook
readonly priority = 10 // Execution order (lower = earlier)
protected async onInit(): Promise<void> {
// Initialize your augmentation
}
async execute<T>(
operation: string,
params: any,
context?: AugmentationContext
): Promise<T | void> {
// Your augmentation logic
if (operation === 'addNoun') {
console.log('Noun added:', params)
}
}
protected async onShutdown(): Promise<void> {
// Cleanup
}
}
```
---
## Augmentation Timing & Priority
### Timing Options
- **`before`**: Runs before the operation (can modify params)
- **`after`**: Runs after the operation (can see results)
- **`both`**: Runs before AND after
### Priority (lower = earlier)
1. Storage augmentations (priority: 0)
2. Cache/Index augmentations (priority: 5-10)
3. Monitoring/Metrics (priority: 15-20)
4. Conduits/Synapses (priority: 20-30)
---
## Key Integration Points
### Where Augmentations Hook In
**BrainyData Constructor**:
- Storage augmentations register based on config
- Cache/Index augmentations auto-register if enabled
**brain.init()**:
- Two-phase initialization (storage first, then others)
- Augmentations can access brain instance via context
**Operations** (addNoun, search, etc.):
- Augmentations execute based on timing and operations filter
- Can modify params (before) or see results (after)
**brain.shutdown()**:
- All augmentations cleaned up in reverse order
---
## Performance Impact
Most augmentations have minimal overhead:
- **Cache**: ~1ms per search (saves 10-100ms on hits)
- **Index**: ~1ms per operation (saves 100ms+ on queries)
- **Metrics**: <1ms per operation
- **Storage**: Varies by adapter (memory: 0ms, S3: 50-200ms)
---
## Best Practices
1. **Let auto-configuration work**: Most apps need zero manual config
2. **Storage first**: Always configure storage before other augmentations
3. **Use built-in augmentations**: They're optimized and battle-tested
4. **Custom augmentations**: Extend BaseAugmentation for consistency
5. **Respect timing**: Use 'before' to modify, 'after' to observe
6. **Mind priority**: Lower numbers execute first
---
## Troubleshooting
### Augmentation not working?
```typescript
// Check if registered
brain.listAugmentations()
// Check if enabled
brain.isAugmentationEnabled('cache')
// Enable/disable at runtime
brain.enableAugmentation('cache')
brain.disableAugmentation('cache')
```
### Performance issues?
```typescript
// Check augmentation overhead
const stats = brain.getStatistics()
console.log(stats.augmentations)
// Disable non-critical augmentations
brain.disableAugmentation('monitoring')
```

# 🛠️ Brainy Augmentation Developer Guide
> **How to create, test, and use augmentations in Brainy 2.0**
## Quick Start: Your First Augmentation
```typescript
import { BaseAugmentation, BrainyAugmentation, AugmentationContext } from '@soulcraft/brainy'
export class MyFirstAugmentation extends BaseAugmentation {
readonly name = 'my-first-augmentation'
readonly timing = 'after' as const // When to run: before | after | both
readonly operations = ['addNoun'] as const // Which operations to hook
readonly priority = 10 // Execution order (lower = first)
protected async onInit(): Promise<void> {
// Initialize your augmentation
console.log('MyFirstAugmentation initialized!')
}
async execute<T = any>(
operation: string,
params: any,
context?: AugmentationContext
): Promise<T | void> {
// Your augmentation logic
if (operation === 'addNoun') {
console.log('Noun added:', params.noun)
// You can access the brain instance
const stats = await context?.brain.getStatistics()
console.log('Total nouns:', stats.totalNouns)
}
}
protected async onShutdown(): Promise<void> {
// Cleanup
console.log('MyFirstAugmentation shutting down')
}
}
```
## Using Your Augmentation
```typescript
import { BrainyData } from '@soulcraft/brainy'
import { MyFirstAugmentation } from './my-first-augmentation'
const brain = new BrainyData()
// Register before init()
brain.augmentations.register(new MyFirstAugmentation())
await brain.init()
// Now your augmentation runs automatically!
await brain.addNoun('Hello World')
// Console: "Noun added: { id: '...', vector: [...], metadata: {} }"
```
---
## Augmentation Lifecycle
### 1. Registration Phase
```typescript
const aug = new MyAugmentation()
brain.augmentations.register(aug) // Before brain.init()!
```
### 2. Initialization Phase
```typescript
await brain.init() // Calls aug.initialize() internally
// Your onInit() method runs here
```
### 3. Execution Phase
```typescript
await brain.addNoun('data') // Your execute() method runs
```
### 4. Shutdown Phase
```typescript
await brain.shutdown() // Your onShutdown() method runs
```
---
## Timing Options
### `before` - Modify Input
```typescript
class ValidationAugmentation extends BaseAugmentation {
readonly timing = 'before' as const
async execute<T>(operation: string, params: any): Promise<any> {
if (operation === 'addNoun') {
// Validate and/or modify params
if (!params.content) {
throw new Error('Content required')
}
// Return modified params
return { ...params, validated: true }
}
}
}
```
### `after` - React to Results
```typescript
class LoggingAugmentation extends BaseAugmentation {
readonly timing = 'after' as const
async execute<T>(operation: string, params: any): Promise<void> {
if (operation === 'search') {
console.log(`Search for "${params.query}" returned ${params.result.length} results`)
}
// Don't return anything - just observe
}
}
```
### `both` - Before AND After
```typescript
class TimingAugmentation extends BaseAugmentation {
readonly timing = 'both' as const
private startTime?: number
async execute<T>(operation: string, params: any, context?: AugmentationContext): Promise<void> {
if (!this.startTime) {
// Before execution
this.startTime = Date.now()
} else {
// After execution
const duration = Date.now() - this.startTime
console.log(`${operation} took ${duration}ms`)
this.startTime = undefined
}
}
}
```
---
## Operation Hooks
### Core Operations You Can Hook
```typescript
readonly operations = [
'addNoun', // Adding data
'updateNoun', // Updating data
'deleteNoun', // Deleting data
'getNoun', // Retrieving data
'search', // Searching
'find', // Triple Intelligence queries
'addVerb', // Adding relationships
'deleteVerb', // Removing relationships
'clear', // Clearing data
'all' // Hook ALL operations
] as const
```
### Example: Multi-Operation Hook
```typescript
class AuditAugmentation extends BaseAugmentation {
readonly operations = ['addNoun', 'updateNoun', 'deleteNoun'] as const
async execute<T>(operation: string, params: any): Promise<void> {
// Log all data modifications
await this.logToAuditTrail(operation, params)
}
}
```
---
## Accessing Brain Context
```typescript
class ContextAwareAugmentation extends BaseAugmentation {
async execute<T>(
operation: string,
params: any,
context?: AugmentationContext
): Promise<void> {
// Access the brain instance
const brain = context?.brain
if (!brain) return
// Use any brain method
const stats = await brain.getStatistics()
const size = await brain.size()
const results = await brain.search('query')
// Access other augmentations
const cache = brain.augmentations.get('cache')
if (cache) {
await cache.clear()
}
}
}
```
---
## Real-World Examples
### 1. Backup Augmentation
```typescript
class BackupAugmentation extends BaseAugmentation {
readonly name = 'backup'
readonly timing = 'after' as const
readonly operations = ['addNoun', 'updateNoun', 'deleteNoun'] as const
readonly priority = 5
private changes = 0
private readonly backupThreshold = 100
async execute<T>(operation: string, params: any, context?: AugmentationContext): Promise<void> {
this.changes++
if (this.changes >= this.backupThreshold) {
await this.performBackup(context?.brain)
this.changes = 0
}
}
private async performBackup(brain?: any): Promise<void> {
if (!brain) return
const backup = await brain.backup()
await this.saveToCloud(backup)
console.log('Automatic backup completed')
}
}
```
### 2. Rate Limiting Augmentation
```typescript
class RateLimitAugmentation extends BaseAugmentation {
readonly name = 'rate-limit'
readonly timing = 'before' as const
readonly operations = ['search', 'find'] as const
readonly priority = 100 // High priority - run first
private requests = new Map<string, number[]>()
private readonly limit = 100 // 100 requests
private readonly window = 60000 // per minute
async execute<T>(operation: string, params: any): Promise<void> {
const now = Date.now()
const key = params.userId || 'anonymous'
// Get request timestamps
const timestamps = this.requests.get(key) || []
// Remove old timestamps
const recent = timestamps.filter(t => now - t < this.window)
// Check limit
if (recent.length >= this.limit) {
throw new Error('Rate limit exceeded')
}
// Add current request
recent.push(now)
this.requests.set(key, recent)
}
}
```
### 3. Encryption Augmentation
```typescript
class EncryptionAugmentation extends BaseAugmentation {
readonly name = 'encryption'
readonly timing = 'both' as const
readonly operations = ['addNoun', 'getNoun'] as const
readonly priority = 90 // Run early
async execute<T>(operation: string, params: any): Promise<any> {
if (operation === 'addNoun') {
// Encrypt before storing
if (params.metadata?.sensitive) {
params.content = await this.encrypt(params.content)
params.encrypted = true
}
return params
}
if (operation === 'getNoun' && params.result?.encrypted) {
// Decrypt after retrieval
params.result.content = await this.decrypt(params.result.content)
delete params.result.encrypted
return params.result
}
}
}
```
---
## Testing Your Augmentation
```typescript
import { describe, it, expect } from 'vitest'
import { BrainyData } from '@soulcraft/brainy'
import { MyAugmentation } from './my-augmentation'
describe('MyAugmentation', () => {
it('should hook into addNoun', async () => {
const brain = new BrainyData({ storage: 'memory' })
const aug = new MyAugmentation()
// Spy on the execute method
const executeSpy = vi.spyOn(aug, 'execute')
brain.augmentations.register(aug)
await brain.init()
// Trigger the augmentation
await brain.addNoun('test data')
// Verify it was called
expect(executeSpy).toHaveBeenCalledWith(
'addNoun',
expect.objectContaining({ content: 'test data' }),
expect.any(Object)
)
})
})
```
---
## Best Practices
### 1. Use Proper Timing
- `before`: Validation, modification, rate limiting
- `after`: Logging, metrics, side effects
- `both`: Timing, tracing, wrapping
### 2. Set Appropriate Priority
```typescript
// Priority guidelines
100: Critical (auth, rate limiting)
50: Important (validation, transformation)
10: Normal (logging, metrics)
1: Optional (debugging, tracing)
```
### 3. Handle Errors Gracefully
```typescript
async execute<T>(operation: string, params: any): Promise<void> {
try {
await this.riskyOperation()
} catch (error) {
// Log but don't break the main operation
console.error(`Augmentation error in ${this.name}:`, error)
// Optionally report to monitoring
this.reportError(error)
}
}
```
### 4. Be Performance Conscious
```typescript
class CachedAugmentation extends BaseAugmentation {
private cache = new Map<string, any>()
async execute<T>(operation: string, params: any): Promise<any> {
const key = this.getCacheKey(params)
// Check cache first
if (this.cache.has(key)) {
return this.cache.get(key)
}
// Expensive operation
const result = await this.expensiveOperation(params)
this.cache.set(key, result)
return result
}
}
```
### 5. Clean Up Resources
```typescript
protected async onShutdown(): Promise<void> {
// Close connections
await this.connection?.close()
// Clear intervals
clearInterval(this.interval)
// Flush buffers
await this.flush()
// Clear caches
this.cache.clear()
}
```

# Brainy Augmentations
Augmentations are the core extensibility mechanism in Brainy. They allow you to modify, enhance, and extend Brainy's behavior without changing the core code.
## Core Principle: One Interface, Infinite Possibilities
Every augmentation implements the same simple `BrainyAugmentation` interface:
```typescript
interface BrainyAugmentation {
name: string
timing: 'before' | 'after' | 'around' | 'replace'
operations: string[]
priority: number
initialize(context): Promise<void>
execute(operation, params, next): Promise<any>
}
```
This single interface can handle EVERYTHING - from adding AI capabilities to exposing APIs to replacing storage backends.

await brain.init()
```
### With Configuration
```typescript

brain.augmentations.register(
new APIServerAugmentation({
port: 8080,
auth: { required: true }
})
)
await brain.init()
```
## Creating Custom Augmentations
See [Creating Custom Augmentations](./creating-augmentations.md) for a complete guide.
Quick example:
```typescript
class MyAugmentation extends BaseAugmentation {
readonly name = 'my-augmentation'
readonly timing = 'after'
readonly operations = ['add', 'search']
readonly priority = 50
async execute<T>(operation: string, params: any, next: () => Promise<T>): Promise<T> {
console.log(`Before ${operation}`)
const result = await next()
console.log(`After ${operation}`)
return result
}
}
```
## Augmentation Timing
### `before`
Executes before the main operation. Used for:
- Input validation
- Data transformation
- Authentication checks
### `after`
Executes after the main operation. Used for:
- Broadcasting updates
- Syncing to external services
- Logging and metrics
### `around`
Wraps the main operation. Used for:
- Transactions
- Caching
- Error handling
### `replace`
Completely replaces the main operation. Used for:
- Alternative storage backends
- Mock implementations
- Proxy operations
## Priority System
Higher numbers execute first:
- **100**: Critical system operations

# API Server Augmentation
## Overview
The `APIServerAugmentation` is a powerful augmentation that exposes your Brainy instance through REST, WebSocket, and MCP (Model Context Protocol) APIs. It transforms Brainy into a full-featured API server with zero configuration required.
## Features
### 🌐 REST API
Complete CRUD operations and advanced queries through HTTP endpoints.
### 🔌 WebSocket Server
Real-time bidirectional communication with automatic operation broadcasting.
### 🧠 MCP Integration
Built-in Model Context Protocol support for AI agent communication.
### 📊 Operation Broadcasting
Automatically broadcasts all Brainy operations to subscribed WebSocket clients.
### 🔒 Optional Security
Built-in authentication and rate limiting when needed.
## Installation
The APIServerAugmentation is included in Brainy core. No additional installation required.
For Node.js environments, you may want to install optional dependencies:
```bash
npm install express cors ws
```
## Zero-Config Usage
```typescript
import { BrainyData } from 'brainy'
import { APIServerAugmentation } from 'brainy/augmentations'
const brain = new BrainyData()
// Register the API server augmentation
brain.augmentations.register(new APIServerAugmentation())
await brain.init()
// Server is now running at http://localhost:3000
console.log('API Server ready!')
console.log('REST: http://localhost:3000/api/*')
console.log('WebSocket: ws://localhost:3000/ws')
console.log('MCP: http://localhost:3000/api/mcp')
```
## Configuration Options
While zero-config works great, you can customize the server:
```typescript
const apiServer = new APIServerAugmentation({
enabled: true, // Enable/disable the server
port: 3000, // HTTP port
host: '0.0.0.0', // Bind address
cors: {
origin: '*', // CORS allowed origins
credentials: true // Allow credentials
},
auth: {
required: false, // Require authentication
apiKeys: [], // Valid API keys
bearerTokens: [] // Valid bearer tokens
},
rateLimit: {
windowMs: 60000, // Rate limit window (ms)
max: 100 // Max requests per window
}
})
```
## REST API Endpoints
### Health Check
```http
GET /health
```
Returns server status and basic metrics.
### Search
```http
POST /api/search
Content-Type: application/json
{
"query": "search text",
"limit": 10,
"options": {}
}
```
### Add Data
```http
POST /api/add
Content-Type: application/json
{
"content": "data to add",
"metadata": {
"key": "value"
}
}
```
### Get by ID
```http
GET /api/get/:id
```
### Delete
```http
DELETE /api/delete/:id
```
### Create Relationship
```http
POST /api/relate
Content-Type: application/json
{
"source": "id1",
"target": "id2",
"verb": "relates_to",
"metadata": {}
}
```
### Complex Queries
```http
POST /api/find
Content-Type: application/json
{
"where": { "type": "document" },
"like": "machine learning",
"limit": 10
}
```
### Clustering
```http
POST /api/cluster
Content-Type: application/json
{
"algorithm": "kmeans",
"options": {
"k": 5
}
}
```
### Statistics
```http
GET /api/stats
```
### Operation History
```http
GET /api/history
```
## WebSocket API
### Connection
```javascript
const ws = new WebSocket('ws://localhost:3000/ws')
ws.onopen = () => {
console.log('Connected to Brainy WebSocket')
}
ws.onmessage = (event) => {
const msg = JSON.parse(event.data)
console.log('Received:', msg)
}
```
### Subscribe to Operations
```javascript
ws.send(JSON.stringify({
type: 'subscribe',
operations: ['all'] // or specific: ['add', 'search', 'delete']
}))
```
### Search via WebSocket
```javascript
ws.send(JSON.stringify({
type: 'search',
query: 'your search',
limit: 10,
requestId: 'unique-id'
}))
```
### Add Data via WebSocket
```javascript
ws.send(JSON.stringify({
type: 'add',
content: 'data to add',
metadata: {},
requestId: 'unique-id'
}))
```
### Operation Broadcasts
When subscribed, you'll receive real-time updates:
```javascript
{
"type": "operation",
"operation": "add",
"params": { /* sanitized parameters */ },
"timestamp": 1234567890,
"duration": 15
}
```
## MCP (Model Context Protocol)
The MCP endpoint allows AI agents to interact with Brainy:
```http
POST /api/mcp
Content-Type: application/json
{
"method": "search",
"params": {
"query": "find documents about AI"
}
}
```
## Authentication
When authentication is enabled:
### API Key
```http
GET /api/stats
X-API-Key: your-api-key
```
### Bearer Token
```http
GET /api/stats
Authorization: Bearer your-token
```
## Environment Support
### Node.js ✅
Full support with Express, WebSocket, and all features.
### Deno 🚧
Planned support using Deno.serve() or oak framework.
### Browser/Service Worker 🚧
Planned support for intercepting fetch() calls locally.
## How It Works
The APIServerAugmentation hooks into Brainy's augmentation pipeline:
1. **Timing**: Executes `after` operations complete
2. **Operations**: Monitors `all` operations
3. **Broadcasting**: Sends operation details to subscribed clients
4. **History**: Maintains operation history (last 1000 operations)
## Example: Multi-Client Sync
```typescript
// Server
const brain = new BrainyData()
brain.augmentations.register(new APIServerAugmentation())
await brain.init()
// Client 1 - WebSocket subscriber
const ws1 = new WebSocket('ws://localhost:3000/ws')
ws1.onopen = () => {
ws1.send(JSON.stringify({
type: 'subscribe',
operations: ['add', 'delete']
}))
}
ws1.onmessage = (e) => {
console.log('Client 1 received update:', JSON.parse(e.data))
}
// Client 2 - REST API user
fetch('http://localhost:3000/api/add', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
content: 'New data',
metadata: { source: 'client2' }
})
})
// Client 1 automatically receives notification!
```
## Performance Considerations
- **Operation History**: Limited to last 1000 operations
- **WebSocket Heartbeat**: Every 30 seconds
- **Client Timeout**: 60 seconds of inactivity
- **Parameter Sanitization**: Sensitive fields removed, large content truncated
- **Rate Limiting**: In-memory tracking (use Redis in production)
## Security Notes
1. **Default Configuration**: No auth, open CORS - suitable for development
2. **Production**: Enable auth, configure CORS, use HTTPS
3. **Sensitive Data**: Parameters are sanitized before broadcasting
4. **Rate Limiting**: Basic in-memory implementation included
## Comparison with Previous Implementations
The APIServerAugmentation unifies and replaces:
- `BrainyMCPBroadcast` - Node-specific WebSocket/HTTP server
- `WebSocketConduitAugmentation` - WebSocket client functionality
- `ServerSearchAugmentations` - Remote Brainy connections
Benefits of the unified approach:
- Single augmentation for all API needs
- Consistent interface across protocols
- Automatic operation broadcasting
- Environment-aware implementation
- Zero-configuration philosophy
## Advanced Usage
### Custom Operation Filtering
```typescript
class FilteredAPIServer extends APIServerAugmentation {
shouldExecute(operation: string, params: any): boolean {
// Don't broadcast sensitive operations
if (operation === 'delete' && params.sensitive) {
return false
}
return true
}
}
```
### Integration with Other Augmentations
```typescript
const brain = new BrainyData()
// Stack augmentations for complete system
brain.augmentations.register(new WALAugmentation()) // Durability
brain.augmentations.register(new EntityRegistryAugmentation()) // Dedup
brain.augmentations.register(new APIServerAugmentation()) // API
await brain.init()
// All augmentations work together seamlessly!
```
## Troubleshooting
### Server won't start
- Check if port is already in use
- Verify Node.js dependencies are installed: `npm install express cors ws`
- Check console for error messages
### WebSocket connections drop
- Ensure heartbeat responses are handled
- Check for proxy/firewall issues
- Verify CORS configuration
### Authentication not working
- Ensure `auth.required` is set to `true`
- Verify API keys or bearer tokens are correctly configured
- Check request headers are properly formatted
## Future Enhancements
- [ ] Deno server implementation
- [ ] Service Worker implementation
- [ ] GraphQL endpoint
- [ ] gRPC support
- [ ] Built-in SSL/TLS
- [ ] Redis-based rate limiting
- [ ] Prometheus metrics endpoint
- [ ] OpenAPI/Swagger documentation

# Getting Started with Brainy
This guide will help you get up and running with Brainy, the multi-dimensional AI database that combines vector similarity, graph relationships, and metadata filtering.
## Installation
```bash
npm install brainy
```
## Basic Setup
### Simple Initialization
```typescript
import { BrainyData } from 'brainy'
// Create a new Brainy instance with defaults
const brain = new BrainyData()
// Initialize (downloads models if needed)
await brain.init()
// You're ready to go!
```
### Custom Configuration
```typescript
const brain = new BrainyData({
// Storage configuration
storage: {
type: 'filesystem', // or 's3', 'opfs', 'memory'
path: './my-data'
},
// Vector configuration
vectors: {
dimensions: 384,
model: 'all-MiniLM-L6-v2'
},
// Performance tuning
cache: {
enabled: true,
maxSize: 1000
}
})
await brain.init()
```
## Your First Operations
### Adding Data
```typescript
// Add entities (nouns) with automatic embedding generation
const id = await brain.addNoun("The quick brown fox jumps over the lazy dog", {
category: "demo",
timestamp: Date.now()
})
console.log(`Added noun with ID: ${id}`)
// Add relationships (verbs) between entities
const sourceId = await brain.addNoun("John Smith")
const targetId = await brain.addNoun("TechCorp")
await brain.addVerb(sourceId, targetId, "works_at", {
position: "Engineer",
since: "2024"
})
```
### Searching
```typescript
// Simple semantic search
const results = await brain.search("fast animals")
results.forEach(result => {
console.log(`Found: ${result.content} (score: ${result.score})`)
})
```
### Advanced Queries with find()
```typescript
// Natural language queries - Brainy understands intent!
const results = await brain.find("show me technology articles about AI from 2023")
// Automatically interprets: topic, category, and time range
// Structured queries with vector similarity and metadata filtering
const structured = await brain.find({
like: "artificial intelligence",
where: {
category: "technology",
year: { $gte: 2023 }
},
limit: 10
})
// Complex natural language with multiple filters
const complex = await brain.find("financial reports from Q3 2024 with revenue over 1M")
// Automatically extracts: document type, date range, numeric filters
```
## Common Use Cases
### 1. Semantic Search Engine
```typescript
// Index documents
const documents = [
{ title: "Introduction to AI", content: "AI is transforming..." },
{ title: "Machine Learning Basics", content: "ML algorithms..." },
{ title: "Deep Learning", content: "Neural networks..." }
]
for (const doc of documents) {
await brain.addNoun(doc.content, {
title: doc.title,
type: "document"
})
}
// Search semantically
const results = await brain.search("how do neural networks work")
```
### 2. Recommendation System
```typescript
// Add user interactions as nouns
const interactionId = await brain.addNoun("user viewed product", {
userId: "user123",
productId: "product456",
action: "view",
timestamp: Date.now()
})
// Create relationships between users and products
const userId = await brain.addNoun("user123")
const productId = await brain.addNoun("product456")
await brain.addVerb(userId, productId, "viewed", {
timestamp: Date.now()
})
// Natural language query for recommendations
const recommendations = await brain.find("products similar to what user123 viewed recently")
// Or structured query for similar users
const similar = await brain.find({
like: "user123 interests",
where: { action: "view" },
limit: 5
})
```
### 3. Knowledge Graph
```typescript
// Add entities (nouns) to the knowledge graph
const personId = await brain.addNoun("John Smith, Software Engineer", {
type: "person",
role: "engineer"
})
const companyId = await brain.addNoun("TechCorp, Innovation Leader", {
type: "company",
industry: "technology"
})
// Create relationship
await brain.addVerb(personId, companyId, "works_at", {
since: "2020",
position: "Senior Engineer"
})
// Natural language query for relationships
const colleagues = await brain.find("people who work at TechCorp")
// Or structured query for specific relationships
const results = await brain.find({
connected: {
from: personId,
type: "works_at"
}
})
```
### 4. Real-time Data Processing
```typescript
// Configure for streaming
const brain = new BrainyData({
augmentations: [
new EntityRegistryAugmentation(), // Deduplication
new BatchProcessingAugmentation({ batchSize: 100 }) // Batching
]
})
// Process streaming data
async function processStream(item) {
// Entity registry prevents duplicate nouns
const id = await brain.addNoun(item.content, {
externalId: item.id,
timestamp: item.timestamp
})
// Real-time natural language queries
if (item.urgent) {
const related = await brain.find(`urgent items similar to ${item.content}`)
// Process related items...
}
}
```
## Storage Options
### Development (Memory)
```typescript
const brain = new BrainyData({
storage: { type: 'memory' }
})
// Fast, temporary, perfect for testing
```
### Production (FileSystem)
```typescript
const brain = new BrainyData({
storage: {
type: 'filesystem',
path: '/var/lib/brainy'
}
})
// Persistent, efficient, server-ready
```
### Cloud (S3)
```typescript
const brain = new BrainyData({
storage: {
type: 's3',
bucket: 'my-brainy-data',
region: 'us-east-1'
}
})
// Scalable, distributed, cloud-native
```
### Browser (OPFS)
```typescript
const brain = new BrainyData({
storage: { type: 'opfs' }
})
// Browser-native, persistent, offline-capable
```
## Performance Tips
### 1. Use Batch Operations
```typescript
// Good - batch operations for nouns
const items = ["item1", "item2", "item3"]
for (const item of items) {
await brain.addNoun(item, { batch: true })
}
// Create relationships efficiently
const relationships = [
{ source: id1, target: id2, type: "related" },
{ source: id2, target: id3, type: "similar" }
]
for (const rel of relationships) {
await brain.addVerb(rel.source, rel.target, rel.type)
}
```
### 2. Enable Caching
```typescript
const brain = new BrainyData({
cache: {
enabled: true,
maxSize: 1000,
ttl: 300000 // 5 minutes
}
})
```
### 3. Use Appropriate Limits
```typescript
// Always specify reasonable limits
const results = await brain.search("query", {
limit: 20 // Don't fetch more than needed
})
```
### 4. Index Frequently Queried Fields
```typescript
const brain = new BrainyData({
indexedFields: ['category', 'userId', 'timestamp']
})
```
## Error Handling
```typescript
try {
await brain.addNoun("content", metadata)
} catch (error) {
if (error.code === 'STORAGE_FULL') {
console.error('Storage is full')
} else if (error.code === 'INVALID_INPUT') {
console.error('Invalid input:', error.message)
} else {
console.error('Unexpected error:', error)
}
}
```

# 🤖 Model Loading Guide
Brainy uses AI embedding models to understand and process your data. This guide explains how model loading works and how to handle different scenarios.
## 🚀 Zero Configuration (Default)
**For most developers, no configuration is needed:**
```typescript
const brain = new BrainyData()
await brain.init() // Models load automatically
```
**What happens automatically:**
1. Checks for local models in `./models/`
2. Downloads All-MiniLM-L6-v2 if needed (384 dimensions)
3. Configures optimal settings for your environment
4. Ready to use immediately
## 📦 Model Loading Cascade
Brainy tries multiple sources in this order:
```
1. LOCAL CACHE (./models/)
↓ (if not found)
2. CDN DOWNLOAD (fast mirrors)
↓ (if fails)
3. GITHUB RELEASES (github.com/xenova/transformers.js)
↓ (if fails)
4. HUGGINGFACE HUB (huggingface.co)
↓ (if fails)
5. FALLBACK STRATEGIES (different model variants)
```
## 🌍 Environment-Specific Behavior
### Browser
```typescript
// Automatically configured for browsers
const brain = new BrainyData() // Works in React, Vue, vanilla JS
await brain.init() // Downloads models via CDN
```
### Node.js Development
```typescript
// Zero config - downloads to ./models/
const brain = new BrainyData()
await brain.init() // Downloads once, cached forever
```
### Production Server
```typescript
// Preload models during build/deployment
const brain = new BrainyData()
await brain.init() // Uses cached local models
```
### Docker/Kubernetes
```dockerfile
# Dockerfile - preload models
RUN npm run download-models
ENV BRAINY_ALLOW_REMOTE_MODELS=false
```
## 🛠️ Manual Model Management
### Pre-download Models
```bash
# Download models during build/deployment
npm run download-models
# Custom location
BRAINY_MODELS_PATH=./my-models npm run download-models
```
### Verify Models
```bash
# Check if models exist
ls ./models/Xenova/all-MiniLM-L6-v2/
# Should see:
# - config.json
# - tokenizer.json
# - onnx/model.onnx
```
### Custom Model Path
```typescript
const brain = new BrainyData({
embedding: {
cacheDir: './custom-models'
}
})
```
## 🔒 Offline & Air-Gapped Environments
### Complete Offline Setup
```bash
# 1. Download models on connected machine
npm run download-models
# 2. Copy models to offline machine
cp -r ./models /path/to/offline/project/
# 3. Force local-only mode
export BRAINY_ALLOW_REMOTE_MODELS=false
```
### Container/Server Deployment
```dockerfile
FROM node:18
WORKDIR /app
COPY package*.json ./
RUN npm ci
# Download models during build
RUN npm run download-models
# Force local-only in production
ENV BRAINY_ALLOW_REMOTE_MODELS=false
COPY . .
EXPOSE 3000
CMD ["npm", "start"]
```
## ⚙️ Environment Variables
### BRAINY_ALLOW_REMOTE_MODELS
Controls whether remote model downloads are allowed:
```bash
# Allow remote downloads (default in most environments)
export BRAINY_ALLOW_REMOTE_MODELS=true
# Force local-only (recommended for production)
export BRAINY_ALLOW_REMOTE_MODELS=false
```
### BRAINY_MODELS_PATH
Custom model storage location:
```bash
# Custom model path
export BRAINY_MODELS_PATH=/opt/brainy/models
# Relative path
export BRAINY_MODELS_PATH=./my-custom-models
```
## 🚨 Troubleshooting
### "Failed to load embedding model" Error
**Cause**: Models not found locally and remote download blocked/failed.
**Solutions**:
```bash
# Option 1: Allow remote downloads
export BRAINY_ALLOW_REMOTE_MODELS=true
# Option 2: Download models manually
npm run download-models
# Option 3: Check internet connectivity
ping huggingface.co
# Option 4: Use custom model path
export BRAINY_MODELS_PATH=/path/to/existing/models
```
### Models Download Very Slowly
**Cause**: Network issues or regional restrictions.
**Solutions**:
```bash
# Pre-download during build/CI
npm run download-models
# Use faster mirrors (automatic in newer versions)
# No action needed - Brainy tries multiple CDNs
```
### Container Out of Memory During Model Load
**Cause**: Limited container memory during model initialization.
**Solutions**:
```dockerfile
# Increase memory limit
docker run -m 2g my-app
# Use quantized models (default)
ENV BRAINY_MODEL_DTYPE=q8
# Pre-load models at build time (recommended)
RUN npm run download-models
```
### Permission Denied Creating Model Cache
**Cause**: Write permissions for model cache directory.
**Solutions**:
```bash
# Make directory writable
chmod 755 ./models
# Use custom writable path
export BRAINY_MODELS_PATH=/tmp/brainy-models
# Or use memory-only storage
const brain = new BrainyData({
storage: { forceMemoryStorage: true }
})
```
## 🎯 Best Practices
### Development
```typescript
// ✅ Zero config - just works
const brain = new BrainyData()
await brain.init()
```
### Production
```dockerfile
# ✅ Pre-download models
RUN npm run download-models
# ✅ Force local-only
ENV BRAINY_ALLOW_REMOTE_MODELS=false
# ✅ Verify models exist
RUN test -f ./models/Xenova/all-MiniLM-L6-v2/onnx/model.onnx
```
### CI/CD Pipeline
```yaml
# .github/workflows/build.yml
- name: Download AI Models
run: npm run download-models
- name: Verify Models
run: |
test -f ./models/Xenova/all-MiniLM-L6-v2/onnx/model.onnx
echo "✅ Models verified"
- name: Test Offline Mode
env:
BRAINY_ALLOW_REMOTE_MODELS: false
run: npm test
```
### Lambda/Serverless
```typescript
// ✅ Models in deployment package
const brain = new BrainyData({
embedding: {
localFilesOnly: true, // No downloads in lambda
cacheDir: './models' // Bundled with deployment
}
})
```
## 📊 Model Information
### All-MiniLM-L6-v2 (Default)

```typescript
// Before: OpenAI API calls
const response = await openai.embeddings.create({
model: "text-embedding-ada-002",
input: "Your text"
})
// After: Local Brainy embeddings
const brain = new BrainyData()
await brain.init() // One-time setup
const id = await brain.add("Your text") // Embedded automatically
```
### From Sentence Transformers
```python
# Before: Python sentence-transformers
from sentence_transformers import SentenceTransformer
model = SentenceTransformer('all-MiniLM-L6-v2')
# After: JavaScript Brainy (same model!)
const brain = new BrainyData() // Uses same all-MiniLM-L6-v2
await brain.init()
```
## 🚀 Advanced Configuration
### Custom Embedding Options
```typescript
const brain = new BrainyData({
embedding: {
model: 'Xenova/all-MiniLM-L6-v2', // Default
dtype: 'q8', // Quantized for speed
device: 'cpu', // CPU inference
localFilesOnly: false, // Allow downloads
verbose: true // Debug logging
}
})
```
### Multiple Model Support (Advanced)
```typescript
// Use custom embedding function
import { createEmbeddingFunction } from 'brainy'
const customEmbedder = createEmbeddingFunction({
model: 'Xenova/all-MiniLM-L12-v2', // Larger model
dtype: 'fp32' // Higher precision
})
const brain = new BrainyData({
embeddingFunction: customEmbedder
})
```

# Natural Language Queries with Brainy
> **Current Status**: Basic natural language support with 220+ patterns. Advanced NLP features coming in Q1 2025.
Brainy's `find()` method understands natural language, allowing you to query your data using plain English instead of complex query syntax.
## Overview
The natural language processing (NLP) system is powered by 220+ pre-computed patterns that understand common query intents, temporal expressions, numeric comparisons, and domain-specific terminology.
## What Works Today
The current NLP implementation supports:
- ✅ Basic pattern matching (220+ patterns)
- ✅ Simple temporal expressions ("recent", "today", "last week")
- ✅ Common query intents ("find", "show", "search")
- ✅ Domain keywords recognition
- ⚠️ Limited entity extraction
- ⚠️ Basic numeric comparisons
## Basic Usage
```typescript
import { BrainyData } from 'brainy'
const brain = new BrainyData()
await brain.init()
// Simply ask in natural language
const results = await brain.find("show me recent articles about AI")
```
## Supported Query Types
### ✅ Currently Working
These query patterns are supported today.
### ⚠️ Basic Support
These work with limitations.
### 🚧 Coming Soon
Planned for future releases.
### Temporal Queries ⚠️ Basic Support
```typescript
// Relative time expressions
await brain.find("documents from last week")
await brain.find("posts created yesterday")
await brain.find("data from the past 30 days")
// Specific dates and ranges
await brain.find("articles published in Q3 2024")
await brain.find("reports from January to March")
await brain.find("meetings scheduled for tomorrow")
// Named periods
await brain.find("quarterly reports from this year")
await brain.find("summer vacation photos")
await brain.find("holiday sales data")
```
### Numeric Filters ⚠️ Basic Support
```typescript
// Comparisons
await brain.find("products with price under $100")
await brain.find("articles with more than 1000 views")
await brain.find("employees with salary above 75000")
// Ranges
await brain.find("items priced between $50 and $200")
await brain.find("posts with 10 to 50 likes")
await brain.find("companies with 100-500 employees")
// Percentages and metrics
await brain.find("stocks with growth over 20%")
await brain.find("projects with completion above 80%")
await brain.find("products with 5 star ratings")
```
### Entity and Relationship Queries 🚧 Coming Soon
```typescript
// People and organizations
await brain.find("articles by John Smith")
await brain.find("employees at TechCorp")
await brain.find("papers from Stanford University")
// Relationships
await brain.find("documents related to Project X")
await brain.find("products similar to iPhone")
await brain.find("people who work with Sarah")
// Ownership and attribution
await brain.find("repos owned by user123")
await brain.find("designs created by the marketing team")
await brain.find("patents filed by Apple")
```
### Combined Complex Queries 🚧 Coming Soon
```typescript
// Multiple conditions
await brain.find("verified research papers about machine learning from 2024 with high citations")
// Business queries
await brain.find("quarterly financial reports from Q2 2024 with revenue over 10M")
// Content queries
await brain.find("popular blog posts by tech influencers published this month about AI")
// E-commerce queries
await brain.find("electronics under $500 with 4+ star reviews and free shipping")
// Academic queries
await brain.find("peer-reviewed papers on quantum computing published in Nature after 2020")
```
## How It Works
### 1. Pattern Matching
The NLP system first matches your query against 220+ pre-built patterns to identify:
- Query intent (search, filter, aggregate)
- Temporal expressions
- Numeric comparisons
- Entity mentions
- Relationship indicators
### 2. Entity Extraction
Named entities are extracted and classified:
- People names
- Organization names
- Product names
- Locations
- Dates and times
### 3. Intent Classification
The query intent is determined:
- **Search**: Finding similar items
- **Filter**: Applying specific criteria
- **Aggregate**: Grouping or summarizing
- **Navigate**: Following relationships
### 4. Query Construction
The natural language is converted to a structured Triple Intelligence query:
```typescript
// Input: "recent AI papers with high citations"
// Output:
{
like: "AI papers",
where: {
type: "paper",
citations: { $gte: 100 },
published: { $gte: "2024-01-01" }
},
boost: "recent"
}
```
### 5. Execution
The structured query is executed using Triple Intelligence, combining:
- Vector similarity search
- Metadata filtering
- Graph traversal
## Advanced Features
### Contextual Understanding 🚧 Coming Soon
```typescript
// Brainy understands context and synonyms
await brain.find("latest ML research") // Understands ML = Machine Learning
await brain.find("top rated items") // Understands top = high score/rating
await brain.find("trending topics") // Understands trending = recent + popular
```
### Fuzzy Matching 🚧 Coming Soon
```typescript
// Handles typos and variations
await brain.find("articals about blockchian") // Still finds blockchain articles
await brain.find("Jon Smith papers") // Matches "John Smith"
```
### Domain-Specific Understanding ⚠️ Basic Support
```typescript
// Tech domain
await brain.find("repos with MIT license")
await brain.find("APIs with OAuth support")
await brain.find("npm packages with zero dependencies")
// Business domain
await brain.find("SaaS companies with ARR over 1M")
await brain.find("startups in Series A")
await brain.find("B2B products with enterprise pricing")
// Academic domain
await brain.find("papers with h-index above 50")
await brain.find("journals with impact factor over 10")
await brain.find("conferences with double-blind review")
```
## Fallback to Structured Queries
When natural language isn't sufficient, you can always use structured queries:
```typescript
// Structured query for precise control
const results = await brain.find({
$and: [
{ $vector: { $similar: "neural networks", threshold: 0.8 } },
{ category: "research" },
{ year: { $gte: 2023 } },
{ $or: [
{ author: "LeCun" },
{ author: "Hinton" },
{ author: "Bengio" }
]}
],
limit: 50
})
```
## Performance Tips
1. **Be specific**: More specific queries execute faster
2. **Use proper nouns**: Names and specific terms improve accuracy
3. **Include time frames**: Temporal filters reduce search space
4. **Specify limits**: Always include reasonable result limits
## Examples by Use Case
### Customer Support
```typescript
await brain.find("urgent tickets from VIP customers today")
await brain.find("unresolved issues older than 3 days")
await brain.find("positive feedback about product X this month")
```
### Content Management
```typescript
await brain.find("draft posts scheduled for next week")
await brain.find("published articles needing review")
await brain.find("videos with over 10k views")
```
### E-commerce
```typescript
await brain.find("best selling products in electronics")
await brain.find("items with low stock under 10 units")
await brain.find("orders from California pending shipping")
```
### Analytics
```typescript
await brain.find("user sessions longer than 5 minutes yesterday")
await brain.find("conversion events from mobile users")
await brain.find("page views for /pricing in the last hour")
```
## Limitations
While powerful, the NLP system has some limitations:
1. **Complex logic**: Very complex boolean logic may require structured queries
2. **Ambiguity**: Ambiguous queries may not parse as expected
3. **Domain terms**: Highly specialized terminology may need training
4. **Languages**: Currently optimized for English queries
## Best Practices
1. **Start simple**: Begin with simple queries and add complexity
2. **Test understanding**: Use explain mode to see how queries are interpreted
3. **Provide feedback**: Help improve the system by reporting misunderstood queries
4. **Combine approaches**: Use NLP for exploration, structured for precision

# 🚨 Troubleshooting Guide
Common issues and solutions for Brainy.
## 🤖 Model Loading Issues
### "Failed to load embedding model"
**Symptoms**: Error during `brain.init()` with model loading failure.
**Causes & Solutions**:
1. **No local models + remote downloads blocked**
```bash
# Solution: Download models manually
npm run download-models
```
2. **Network connectivity issues**
```bash
# Solution: Allow remote models
export BRAINY_ALLOW_REMOTE_MODELS=true
# Or pre-download in connected environment
npm run download-models
```
3. **Incorrect model path**
```bash
# Check if models exist
ls ./models/Xenova/all-MiniLM-L6-v2/onnx/model.onnx
# Set correct path
export BRAINY_MODELS_PATH=/correct/path/to/models
```
### Models Download Very Slowly
**Symptoms**: Long wait times during first initialization.
**Solutions**:
```bash
# Pre-download during build/CI
npm run download-models
# For Docker - download during image build
RUN npm run download-models
```
### Container Out of Memory During Model Load
**Symptoms**: OOM errors in Docker/Kubernetes during initialization.
**Solutions**:
```dockerfile
# Increase memory limit
docker run -m 2g my-app
# Pre-download models at build time (recommended)
RUN npm run download-models
# Use quantized models (default, but explicit)
ENV BRAINY_MODEL_DTYPE=q8
```
## 💾 Storage Issues
### Permission Denied Creating Storage Directory
**Symptoms**: EACCES or permission errors when creating storage files.
**Solutions**:
```bash
# Make directory writable
chmod 755 ./brainy-data
# Use custom writable path
const brain = new BrainyData({
storage: {
adapter: 'filesystem',
path: '/tmp/brainy-data'
}
})
# Or use memory storage
const brain = new BrainyData({
storage: { forceMemoryStorage: true }
})
```
### "ENOENT: no such file or directory"
**Symptoms**: File not found errors during storage operations.
**Solutions**:
```bash
# Ensure parent directory exists
mkdir -p ./brainy-data
# Check storage configuration
const brain = new BrainyData({
storage: {
adapter: 'filesystem',
path: '/full/path/to/storage' // Use absolute path
}
})
```
## 🧠 Initialization Issues
### Initialization Hangs or Times Out
**Symptoms**: `brain.init()` never resolves.
**Possible Causes & Solutions**:
1. **Model download timeout**
```bash
# Pre-download models
npm run download-models
# Or force local-only
export BRAINY_ALLOW_REMOTE_MODELS=false
```
2. **Network issues**
```typescript
// Set initialization timeout
const brain = new BrainyData()
// Use Promise.race for timeout
const initPromise = Promise.race([
brain.init(),
new Promise((_, reject) =>
setTimeout(() => reject(new Error('Init timeout')), 30000)
)
])
```
3. **Resource constraints**
```bash
# Increase memory for Node.js
NODE_OPTIONS="--max-old-space-size=4096" npm start
```
## 🔍 Search Issues
### No Search Results
**Symptoms**: Empty results from valid queries.
**Debugging Steps**:
1. **Check if data exists**
```typescript
const stats = await brain.getStatistics()
console.log(`Total items: ${stats.nounCount}`)
```
2. **Verify embedding generation**
```typescript
const id = await brain.add("test content")
const item = await brain.get(id)
console.log('Item:', item) // Should have metadata and vector
```
3. **Test with exact match**
```typescript
const results = await brain.search("test content") // Exact text
console.log('Exact match results:', results)
```
### Poor Search Quality
**Symptoms**: Irrelevant results, low scores.
**Improvements**:
1. **Add more context to queries**
```typescript
// Instead of: "cat"
const results = await brain.search("domestic cat animal pet")
```
2. **Use metadata filtering**
```typescript
const results = await brain.search("animals", {
where: { category: "pets" },
limit: 10
})
```
3. **Check data quality**
```typescript
// Ensure consistent, descriptive content
await brain.add("Domestic cat - small carnivorous mammal", {
category: "animals",
subcategory: "pets"
})
```
## ⚡ Performance Issues
### Slow Search Performance
**Symptoms**: High search latency.
**Optimizations**:
1. **Enable search cache**
```typescript
const brain = new BrainyData({
cache: {
search: {
maxSize: 1000,
ttl: 300000 // 5 minutes
}
}
})
```
2. **Use appropriate limits**
```typescript
// Don't fetch more than needed
const results = await brain.search("query", { limit: 10 })
```
3. **Consider metadata filtering first**
```typescript
// Filter by metadata first, then semantic search
const results = await brain.search("query", {
where: { category: "specific" }, // Reduces search space
limit: 10
})
```
### High Memory Usage
**Symptoms**: Increasing memory consumption over time.
**Solutions**:
1. **Cleanup when done**
```typescript
await brain.cleanup() // Releases resources
```
2. **Use streaming for large datasets**
```typescript
// Process in batches instead of loading all at once
for (let i = 0; i < data.length; i += 100) {
const batch = data.slice(i, i + 100)
await Promise.all(batch.map(item => brain.add(item)))
}
```
3. **Configure memory limits**
```bash
NODE_OPTIONS="--max-old-space-size=2048" npm start
```
## 🧪 Testing Issues
### Tests Fail in CI/CD
**Symptoms**: Tests pass locally but fail in automated environments.
**Solutions**:
1. **Pre-download models in CI**
```yaml
# .github/workflows/test.yml
- name: Download Models
run: npm run download-models
- name: Test with Local Models
env:
BRAINY_ALLOW_REMOTE_MODELS: false
run: npm test
```
2. **Use memory storage in tests**
```typescript
// In test setup
const brain = new BrainyData({
storage: { forceMemoryStorage: true }
})
```
3. **Increase timeout for CI**
```typescript
// In test files
describe('Brainy tests', () => {
it('should work', async () => {
// Test code
}, { timeout: 30000 }) // 30 second timeout
})
```
## 📋 Environment-Specific Issues
### Browser CORS Errors
**Symptoms**: Model loading fails in browser due to CORS.
**Solutions**:
```javascript
// Brainy handles CORS automatically via CDN
// No action needed - models load from CORS-enabled mirrors
// If using custom model URLs, ensure CORS headers:
// Access-Control-Allow-Origin: *
```
### Serverless Cold Start Timeouts
**Symptoms**: Lambda/Vercel functions timeout during initialization.
**Solutions**:
```dockerfile
# Pre-bundle models in deployment
RUN npm run download-models
# Set environment variables
ENV BRAINY_ALLOW_REMOTE_MODELS=false
ENV BRAINY_MODELS_PATH=./models
```
### Node.js Module Resolution Issues
**Symptoms**: "Cannot find module" errors.
**Solutions**:
```json
// package.json
{
"type": "module",
"exports": {
".": {
"import": "./dist/index.js",
"require": "./dist/index.js"
}
}
}
```
## 🆘 Getting Help
### Debug Logging
Enable verbose logging to see what's happening:
```typescript
const brain = new BrainyData({
logging: { verbose: true }
})
```
### Health Check
Verify your Brainy setup:
```typescript
// Basic health check
try {
const brain = new BrainyData()
await brain.init()
const id = await brain.add("health check")
const results = await brain.search("health")
console.log('✅ Brainy is working correctly')
console.log(`Added item: ${id}`)
console.log(`Search results: ${results.length}`)
} catch (error) {
console.error('❌ Brainy health check failed:', error)
}
```
