# 🚀 Brainy Quick Start Guide
Get up and running with Brainy in 5 minutes!
## Installation
```bash
npm install @soulcraft/brainy
```
Or install globally for CLI access:
```bash
npm install -g brainy
```
## Basic Usage
### 1. Initialize Brainy
```javascript
import { Brainy, NounType } from '@soulcraft/brainy'
const brain = new Brainy()
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.add("JavaScript is a versatile programming language", { nounType: NounType.Concept })
// Add with metadata
await brain.add("React is a JavaScript library", {
nounType: NounType.Concept,
type: "library",
category: "frontend",
popularity: "high"
})
// Add structured data
await brain.add({
title: "Introduction to TypeScript",
content: "TypeScript adds static typing to JavaScript",
author: "John Doe"
}, {
nounType: NounType.Document,
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 { Brainy, NounType } from '@soulcraft/brainy'
import fs from 'fs'
const brain = new Brainy({
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.add(doc.content, {
nounType: NounType.Document,
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 { Brainy, NounType } from '@soulcraft/brainy'
const brain = new Brainy()
await brain.init()
class ChatWithMemory {
constructor(brain) {
this.brain = brain
this.sessionId = Date.now().toString()
}
async addMessage(role, content) {
await this.brain.add(content, {
nounType: NounType.Message,
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 { Brainy, NounType } from '@soulcraft/brainy'
import { glob } from 'glob'
import fs from 'fs'
const brain = new Brainy()
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.add(content, {
nounType: NounType.File,
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 Brainy() // Default
```
### FileSystem (Development)
```javascript
const brain = new Brainy({
storage: {
type: 'filesystem',
path: './brain-data'
}
})
```
### Browser (OPFS)
```javascript
const brain = new Brainy({
storage: { type: 'opfs' }
})
```
### S3 (Production)
```javascript
const brain = new Brainy({
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'`

# 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 @soulcraft/brainy
```
## Basic Setup
### Simple Initialization
```typescript
import { Brainy } from '@soulcraft/brainy'
// Create a new Brainy instance with defaults
const brain = new Brainy()
// Initialize (downloads models if needed)
await brain.init()
// You're ready to go!
```
### Custom Configuration
```typescript
const brain = new Brainy({
// Storage configuration
storage: {
type: 'filesystem', // or 's3', 'opfs'
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.add("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.add("John Smith", { nounType: 'person' })
const targetId = await brain.add("TechCorp", { nounType: 'organization' })
await brain.relate(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.add(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.add("user viewed product", {
userId: "user123",
productId: "product456",
action: "view",
timestamp: Date.now()
})
// Create relationships between users and products
const userId = await brain.add("user123", { nounType: 'user' })
const productId = await brain.add("product456", { nounType: 'product' })
await brain.relate(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.add("John Smith, Software Engineer", {
type: "person",
role: "engineer"
})
const companyId = await brain.add("TechCorp, Innovation Leader", {
type: "company",
industry: "technology"
})
// Create relationship
await brain.relate(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 Brainy({
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.add(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 (FileSystem)
```typescript
const brain = new Brainy({
storage: { type: 'filesystem', path: '/tmp/brainy-dev' }
})
// Fast, persistent, perfect for testing
```
### Production (FileSystem)
```typescript
const brain = new Brainy({
storage: {
type: 'filesystem',
path: '/var/lib/brainy'
}
})
// Persistent, efficient, server-ready
```
### Cloud (S3)
```typescript
const brain = new Brainy({
storage: {
type: 's3',
bucket: 'my-brainy-data',
region: 'us-east-1'
}
})
// Scalable, distributed, cloud-native
```
### Browser (OPFS)
```typescript
const brain = new Brainy({
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.add(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.relate(rel.source, rel.target, rel.type)
}
```
### 2. Enable Caching
```typescript
const brain = new Brainy({
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 Brainy({
indexedFields: ['category', 'userId', 'timestamp']
})
```
## Error Handling
```typescript
try {
await brain.add("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)
}
}
```

# VFS Initialization Guide # VFS Initialization Guide (v5.1.0+)
## Quick Start ## Quick Start
The Brainy VFS requires proper initialization before use. Here's the correct pattern: The Brainy VFS is automatically initialized during `brain.init()`. No separate initialization needed!
```javascript ```javascript
import { Brainy } from '@soulcraft/brainy' import { Brainy } from '@soulcraft/brainy'
// Step 1: Create and initialize Brainy // Create and initialize Brainy
const brain = new Brainy({ const brain = new Brainy({
storage: { type: 'filesystem', path: './data' } storage: { type: 'filesystem', path: './data' }
}) })
await brain.init() // VFS is auto-initialized here!
// Use VFS immediately - it's a property, not a method!
await brain.vfs.writeFile('/test.txt', 'Hello World')
const files = await brain.vfs.readdir('/')
```
## What Changed in v5.1.0?
### Before (v4.x and early v5.0.0):
```javascript
const brain = new Brainy(...)
await brain.init() await brain.init()
// Step 2: Get VFS instance (it's a METHOD, not a property!) const vfs = brain.vfs() // ❌ Method call
const vfs = brain.vfs() // ✅ Correct: method call with () await vfs.init() // ❌ Separate initialization
await vfs.writeFile(...)
// Step 3: Initialize VFS (THIS IS REQUIRED!)
await vfs.init() // Creates the root directory
// Now you can use VFS
await vfs.writeFile('/test.txt', 'Hello World')
const files = await vfs.readdir('/')
``` ```
## Common Mistakes ### After (v5.1.0+):
### ❌ Mistake 1: Accessing VFS as Property
```javascript ```javascript
// WRONG - vfs is a method, not a property const brain = new Brainy(...)
const vfs = brain.vfs // Missing parentheses! await brain.init() // VFS auto-initialized!
await brain.vfs.writeFile(...) // ✅ Property access, just works!
``` ```
### ❌ Mistake 2: Forgetting to Initialize VFS ### Key Changes:
1. **`vfs()` → `vfs`**: Method call becomes property access
2. **Auto-initialization**: VFS initialized during `brain.init()`
3. **Zero complexity**: No separate `vfs.init()` call needed
4. **Consistent pattern**: VFS treated like any other brain API
## Migration from v4.x/v5.0.0
### Old Pattern (DEPRECATED):
```javascript ```javascript
const vfs = brain.vfs() const vfs = brain.vfs()
// Missing: await vfs.init() await vfs.init()
await vfs.writeFile('/test.txt', 'data') // Error: VFS not initialized await vfs.writeFile('/test.txt', 'data')
``` ```
### ❌ Mistake 3: Not Waiting for Initialization ### New Pattern (v5.1.0+):
```javascript ```javascript
const vfs = brain.vfs() // Just remove the () and init() call
vfs.init() // Missing await! await brain.vfs.writeFile('/test.txt', 'data')
await vfs.readdir('/') // Error: VFS not initialized (init still running)
``` ```
## Why Initialization is Required ## Why Auto-Initialization?
The VFS `init()` method performs critical setup: VFS stores files as entities and relationships in the same graph as everything else. There's no reason to treat it differently! Auto-initialization:
1. **Creates the root directory entity** in Brainy's graph database - ✅ **Simpler API**: One less step to remember
2. **Initializes the PathResolver** for efficient path lookups - ✅ **Fewer errors**: Can't forget to initialize
3. **Sets up caching layers** for performance - ✅ **More intuitive**: Property access feels natural
4. **Starts background tasks** for maintenance - ✅ **Consistent**: Matches how other brain APIs work
5. **Configures storage adapters** based on your settings
Without initialization, the root directory (`/`) doesn't exist, which is why operations fail with "Not a directory: /" errors.
## Complete Example ## Complete Example
```javascript ```javascript
import { Brainy } from '@soulcraft/brainy' import { Brainy } from '@soulcraft/brainy'
async function setupVFS() { async function useVFS() {
// Initialize Brainy // Initialize Brainy
const brain = new Brainy({ const brain = new Brainy({

path: './brainy-data' path: './brainy-data'
} }
}) })
await brain.init() await brain.init() // VFS ready after this!
// Get and initialize VFS // Use VFS immediately
const vfs = brain.vfs() await brain.vfs.writeFile('/readme.txt', 'Welcome to VFS!')
await vfs.init() await brain.vfs.mkdir('/documents')
// Verify initialization const files = await brain.vfs.readdir('/')
const rootExists = await vfs.exists('/') console.log('Files in root:', files.map(f => f.name))
console.log('Root directory exists:', rootExists) // true
const stats = await vfs.stat('/') const content = await brain.vfs.readFile('/readme.txt')
console.log('Root is directory:', stats.isDirectory()) // true console.log('File content:', content.toString())
// Now use VFS normally
await vfs.writeFile('/readme.txt', 'Welcome to VFS!')
await vfs.mkdir('/documents')
const files = await vfs.readdir('/')
console.log('Files in root:', files) // ['readme.txt', 'documents']
return vfs
} }
setupVFS().catch(console.error) useVFS().catch(console.error)
``` ```
## Error Messages
If you see this error:
```
VFS not initialized. You must call await vfs.init() after getting the VFS instance.
Example:
const vfs = brain.vfs() // Note: vfs() is a method, not a property
await vfs.init() // This creates the root directory
```
It means you forgot to initialize VFS. Follow the example in the error message.

## Auto-Initialization Pattern (Optional) ## Error Messages
If you want VFS to auto-initialize on first use: If you see this error:
```
Brainy not initialized. Call init() first.
```
It means you tried to use VFS before calling `brain.init()`. Always initialize Brainy first:
```javascript ```javascript
class AutoInitVFS { await brain.init() // Required!
constructor(config) { await brain.vfs.writeFile(...) // Now this works
this.brain = new Brainy(config) ```
this.vfs = null
this.initPromise = null
}
async ensureInit() { ## Fork Support (v5.0.0+)
if (!this.initPromise) {
this.initPromise = this._initialize()
}
await this.initPromise
}
async _initialize() { VFS works seamlessly with Brainy's Copy-on-Write (COW) fork feature:
await this.brain.init()
this.vfs = this.brain.vfs()
await this.vfs.init()
}
// Wrap all VFS methods ```javascript
async writeFile(path, data) { const brain = new Brainy({ storage: { type: 'memory' } })
await this.ensureInit() await brain.init()
return this.vfs.writeFile(path, data)
}
async readdir(path) { // Create files in parent
await this.ensureInit() await brain.vfs.writeFile('/config.json', '{"version": 1}')
return this.vfs.readdir(path)
}
}
// Usage - no explicit init needed // Fork inherits parent's files
const vfs = new AutoInitVFS({ storage: { type: 'memory' } }) const fork = await brain.fork('experiment')
await vfs.writeFile('/test.txt', 'Auto-init works!') const files = await fork.vfs.readdir('/') // Sees parent's config.json!
// Fork modifications are isolated
await fork.vfs.writeFile('/test.txt', 'Fork only')
await brain.vfs.readdir('/') // Parent doesn't see test.txt
``` ```
## FAQ ## FAQ
### Q: Why doesn't VFS auto-initialize? ### Q: Do I need to call `vfs.init()` anymore?
A: Explicit initialization gives you control over when the root directory is created and when background tasks start. This prevents unexpected side effects and makes the initialization cost visible. **A:** No! VFS is automatically initialized during `brain.init()` in v5.1.0+.
### Q: Can I reinitialize VFS? ### Q: Why did the API change from `vfs()` to `vfs`?
A: No, VFS can only be initialized once per instance. If you need to reset, create a new Brainy instance. **A:** VFS uses the same entity/relationship graph as everything else. There's no reason to treat it differently from other brain APIs.
### Q: What happens if Brainy isn't initialized? ### Q: Will my old code break?
A: VFS initialization will fail. Always initialize Brainy first with `await brain.init()`. **A:** If you're using `brain.vfs()` or `await vfs.init()`, you'll need to update to the new pattern. The migration is simple - just remove the `()` and `init()` calls.
### Q: Is the initialization pattern the same for all storage types? ### Q: Can I still configure VFS?
A: Yes, whether using memory, filesystem, S3, or R2 storage, the initialization pattern is identical. **A:** Yes, VFS configuration is passed through `brain.init()` config. The VFS-specific options are applied during auto-initialization.
### Q: Does this work with all storage adapters?
**A:** Yes! VFS auto-initialization works with all storage adapters: Memory, FileSystem, OPFS, S3, R2, Azure Blob, and Google Cloud Storage.
### Q: What if I need multiple VFS instances?
**A:** Each Brainy instance has its own VFS. Create multiple Brainy instances if you need multiple VFS instances.
