- -## 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') }, -

-### 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, -

- // 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') -

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'` -

This prevents unexpected side effects and makes the initialization cost visible. +### Q: Do I need to call `vfs.init()` anymore? +**A:** No! VFS is automatically initialized during `brain.init()` in v5.1.0+. -### Q: Can I reinitialize VFS? -A: No, VFS can only be initialized once per instance. If you need to reset, create a new Brainy instance. +### Q: Why did the API change from `vfs()` to `vfs`? +**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? -A: VFS initialization will fail. Always initialize Brainy first with `await brain.init()`. +### Q: Will my old code break? +**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? -A: Yes, whether using memory, filesystem, S3, or R2 storage, the initialization pattern is identical. +### Q: Can I still configure VFS? +**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. ## Related Documentation - [VFS Quick Start](./QUICK_START.md) - 5-minute setup guide - [VFS API Guide](./VFS_API_GUIDE.md) - Complete API reference -- [Common Patterns](./COMMON_PATTERNS.md) -
