All necessary TensorFlow.js packages are automatically installed when you install Brainy. Note: If you encounter dependency conflicts with TensorFlow.js packages, you may need to use the `--legacy-peer-deps` flag: ```bash npm install @soulcraft/brainy --legacy-peer-deps ``` ## 🏁 Quick Start Brainy now uses a unified build that automatically adapts to your environment (Node.js, browser, or serverless), so you can use the same code everywhere! ```typescript import {BrainyData, NounType, VerbType, environment} from '@soulcraft/brainy' // Check which environment we're running in (optional) console.log(`Running in ${environment.isBrowser ? 'browser' : environment.isNode ? 'Node.js' : 'serverless'} environment`) // Create and initialize the database const db = new BrainyData() await db.init() // Add data (automatically converted to vectors) const catId = await db.add("Cats are independent pets", { noun: NounType.Thing, category: 'animal' }) const dogId = await db.add("Dogs are loyal companions", { noun: NounType.Thing, category: 'animal' }) // Search for similar items const results = await db.searchText("feline pets", 2) console.log(results) // Returns items similar to "feline pets" with similarity scores // Add a relationship between items await db.addVerb(catId, dogId, { verb: VerbType.RelatedTo, description: 'Both are common household pets' }) ``` ### Usage Options Brainy's unified build works in all environments, but you have several import options: ```typescript // Standard import - automatically adapts to any environment import {BrainyData, NounType, VerbType, environment} from '@soulcraft/brainy' // Minified version for production import {BrainyData, NounType, VerbType} from '@soulcraft/brainy/min' // Use the same API in any environment const db = new BrainyData() await db.init() // ... ``` #### Using a script tag in HTML ```html ``` Modern bundlers like Webpack, Rollup, and Vite will automatically use the unified build which adapts to any environment. ## 🧩 How It Works (The Magic Behind the Curtain) Brainy combines four key technologies to create its adaptive intelligence: 1. **Vector Embeddings** - Converts data (text, images, etc.) into numerical vectors that capture semantic meaning ( translating your data into brain-speak!) 2. **HNSW Algorithm** - Enables fast similarity search through a hierarchical graph structure (like a super-efficient treasure map for your data) 3. **Adaptive Environment Detection** - Automatically senses your platform and optimizes accordingly: - Adjusts performance parameters based on available resources - Learns from query patterns to optimize future searches - Tunes itself for your specific use cases the more you use it 4. **Intelligent Storage Selection** - Uses the best available storage option for your environment, scaling effortlessly to any data size (from bytes to petabytes!): - Browser: Origin Private File System (OPFS) - Node.js: File system - Server: S3-compatible storage (optional) - Fallback: In-memory storage - Automatically migrates between storage types as needed! ## 🚀 The Brainy Pipeline (Data's Wild Ride!) Brainy's data processing pipeline transforms raw data into searchable, connected knowledge that gets smarter over time. Here's how the magic happens: ``` Raw Data → Embedding → Vector Storage → Graph Connections → Adaptive Learning → Query & Retrieval ``` Each time data flows through this pipeline, Brainy learns a little more about your usage patterns and environment, making future operations even faster and more relevant! ### 🔄 Pipeline Stages (The Journey of Your Data) 1. **Data Ingestion** 🍽️ - Raw text or pre-computed vectors enter the pipeline (dinner time for data!) - Data is validated and prepared for processing (washing hands before eating) 2. **Embedding Generation** 🧠 - Text is transformed into numerical vectors using embedding models (language → math magic) - Uses TensorFlow Universal Sentence Encoder for high-quality text embeddings - Custom embedding functions can be plugged in for specialized domains (bring your own secret sauce) 3. **Vector Indexing** 🔍 - Vectors are indexed using the HNSW algorithm (filing your data in the brain cabinet) - Hierarchical structure enables lightning-fast similarity search (express lanes for your queries) - Configurable parameters for precision vs. performance tradeoffs (dial in your perfect balance) 4. **Graph Construction** 🕸️ - Nouns (entities) become nodes in the knowledge graph (data gets its own social network) - Verbs (relationships) connect related entities (making friends and connections) - Typed relationships add semantic meaning to connections (not just friends, but BFFs) 5. **Adaptive Learning** 🌱 - Analyzes usage patterns to optimize future operations (gets to know your habits) - Tunes performance parameters based on your environment (adapts to your digital home) - Adjusts search strategies based on query history (learns what you're really looking for) - Becomes more efficient and relevant the more you use it (like a good friendship) 6. **Intelligent Storage** 💾 - Data is saved using the optimal storage for your environment (finds the coziest home for your data) - Automatic selection between OPFS, filesystem, S3, or memory (no manual configuration needed!) - Migrates between storage types as your application's needs evolve (moves houses without you noticing) - Scales effortlessly from tiny datasets to massive data collections (from ant-sized to elephant-sized data, no problem!) - Configurable storage adapters for custom persistence needs (design your own dream data home) ### 🧩 Augmentation Types Brainy uses a powerful augmentation system to extend functionality. Augmentations are processed in the following order: 1. **SENSE** 👁️ - Ingests and processes raw, unstructured data into nouns and verbs - Handles text, images, audio streams, and other input formats - Example: Converting raw text into structured entities 2. **MEMORY** 💾 - Provides storage capabilities for data in different formats - Manages persistence across sessions - Example: Storing vectors in OPFS or filesystem 3. **COGNITION** 🧠 - Enables advanced reasoning, inference, and logical operations - Analyzes relationships between entities - Examples: - Inferring new connections between existing data - Deriving insights from graph relationships 4. **CONDUIT** 🔌 - Establishes high-bandwidth channels for structured data exchange - Connects with external systems and syncs between Brainy instances - Two built-in iConduit augmentations for scaling out and syncing: - **WebSocket iConduit** - Syncs data between browsers and servers (like a digital postal service with superpowers!) - **WebRTC iConduit** - Direct peer-to-peer syncing between browsers (like telepathy for your data, no middleman required!) - Examples: - Integrating with third-party APIs - Syncing Brainy instances between browsers using WebSockets - Peer-to-peer syncing between browsers using WebRTC 5. **ACTIVATION** ⚡ - Initiates actions, responses, or data manipulations - Triggers events based on data changes - Example: Sending notifications when new data is processed 6. **PERCEPTION** 🔍 - Interprets, contextualizes, and visualizes identified nouns and verbs - Creates meaningful representations of data - Example: Generating visualizations of graph relationships 7. **DIALOG** 💬 - Facilitates natural language understanding and generation - Enables conversational interactions - Example: Processing user queries and generating responses 8. **WEBSOCKET** 🌐 - Enables real-time communication via WebSockets - Can be combined with other augmentation types - Example: Streaming data processing in real-time ### 🌊 Streaming Data Support Brainy's pipeline is designed to handle streaming data efficiently: 1. **WebSocket Integration** 🔄 - Built-in support for WebSocket connections - Process data as it arrives without blocking - Example: `setupWebSocketPipeline(url, dataType, options)` 2. **Asynchronous Processing** ⚡ - Non-blocking architecture for real-time data handling - Parallel processing of incoming streams - Example: `createWebSocketHandler(connection, dataType, options)` 3. **Event-Based Architecture** 📡 - Augmentations can listen to data feeds and streams - Real-time updates propagate through the pipeline - Example: `listenToFeed(feedUrl, callback)` 4. **Threaded Execution** 🧵 - Optional multi-threading for high-performance streaming - Configurable execution modes (SEQUENTIAL, PARALLEL, THREADED) - Example: `executeTypedPipeline(augmentations, method, args, { mode: ExecutionMode.THREADED })` ### 🏗️ Build System Brainy uses a modern build system that optimizes for both Node.js and browser environments: 1. **ES Modules** 📦 - Built as ES modules for maximum compatibility - Works in modern browsers and Node.js environments - Separate optimized builds for browser and Node.js 2. **Environment-Specific Builds** 🔧 - **Node.js Build**: Optimized for server environments with full functionality - **Browser Build**: Optimized for browser environments with reduced bundle size - Conditional exports in package.json for automatic environment detection 3. **Environment Detection** 🔍 - Automatically detects whether it's running in a browser or Node.js - Loads appropriate dependencies and functionality based on the environment - Provides consistent API across all environments 4. **TypeScript** 📝 - Written in TypeScript for type safety and better developer experience - Generates type definitions for TypeScript users - Compiled to ES2020 for modern JavaScript environments 5. **Build Scripts** 🛠️ - `npm run build`: Builds the Node.js version - `npm run build:browser`: Builds the browser-optimized version - `npm run build:all`: Builds both versions - `npm run demo`: Builds all versions and starts a demo server ### 🏃‍♀️ Running the Pipeline The pipeline runs automatically when you: ```typescript // Add data (runs embedding → indexing → storage) const id = await db.add("Your text data here", {metadata}) // Search (runs embedding → similarity search) const results = await db.searchText("Your query here", 5) // Connect entities (runs graph construction → storage) await db.addVerb(sourceId, targetId, {verb: VerbType.RelatedTo}) ``` Using the CLI: ```bash # Add data through the CLI pipeline brainy add "Your text data here" '{"noun":"Thing"}' # Search through the CLI pipeline brainy search "Your query here" --limit 5 # Connect entities through the CLI brainy addVerb RelatedTo ``` ### 🔧 Extending the Pipeline Brainy's pipeline is designed for extensibility at every stage: 1. **Custom Embedding** 🧩 ```typescript // Create your own embedding function const myEmbedder = async (text) => { // Your custom embedding logic here return [0.1, 0.2, 0.3, ...] // Return a vector } // Use it in Brainy const db = new BrainyData({ embeddingFunction: myEmbedder }) ``` 2. **Custom Distance Functions** 📏 ```typescript // Define your own distance function const myDistance = (a, b) => { // Your custom distance calculation return Math.sqrt(a.reduce((sum, val, i) => sum + Math.pow(val - b[i], 2), 0)) } // Use it in Brainy const db = new BrainyData({ distanceFunction: myDistance }) ``` 3. **Custom Storage Adapters** 📦 ```typescript // Implement the StorageAdapter interface class MyStorage implements StorageAdapter { // Your storage implementation } // Use it in Brainy const db = new BrainyData({ storageAdapter: new MyStorage() }) ``` 4. **Augmentations System** 🧠 ```typescript // Create custom augmentations to extend functionality const myAugmentation = { type: 'memory', name: 'my-custom-storage', // Implementation details } // Register with Brainy db.registerAugmentation(myAugmentation) ``` ## 📝 Data Model Brainy uses a graph-based data model with two primary concepts: ### Nouns (Entities) The main entities in your data (nodes in the graph): - Each noun has a unique ID, vector representation, and metadata - Nouns can be categorized by type (Person, Place, Thing, Event, Concept, etc.) - Nouns are automatically vectorized for similarity search ### Verbs (Relationships) Connections between nouns (edges in the graph): - Each verb connects a source noun to a target noun - Verbs have types that define the relationship (RelatedTo, Controls, Contains, etc.) - Verbs can have their own metadata to describe the relationship ## 🖥️ Command Line Interface Brainy includes a powerful CLI for managing your data: ```bash # Install globally npm install -g @soulcraft/brainy --legacy-peer-deps # Initialize a database brainy init # Add some data brainy add "Cats are independent pets" '{"noun":"Thing","category":"animal"}' brainy add "Dogs are loyal companions" '{"noun":"Thing","category":"animal"}' # Search for similar items brainy search "feline pets" 5 # Add relationships between items brainy addVerb RelatedTo '{"description":"Both are pets"}' # Visualize the graph structure brainy visualize brainy visualize --root --depth 3 ``` ### 🔄 Using During Development ```bash # Run the CLI directly from the source npm run cli help # Generate a random graph for testing npm run cli generate-random-graph --noun-count 20 --verb-count 40 ``` ### 🔍 Available Commands #### Basic Database Operations: -

This implementation uses a hybrid approach combining: 1. **Product Quantization** - Reduces vector dimensionality while preserving similarity relationships 2. **Disk-Based Storage** - Offloads vectors to disk when memory usage exceeds a threshold 3. **Memory-Efficient Indexing** - Optimizes memory usage for large-scale vector collections ```typescript import {BrainyData} from '@soulcraft/brainy' // Configure with optimized HNSW index for large datasets const db = new BrainyData({ // Use the optimized HNSW index instead of the standard one hnswOptimized: { // Standard HNSW parameters M: 16, // Max connections per noun efConstruction: 200, // Construction candidate list size efSearch: 50, // Search candidate list size // Memory threshold in bytes - when exceeded, will use disk-based approach memoryThreshold: 1024 * 1024 * 1024, // 1GB default threshold // Product quantization settings for dimensionality reduction productQuantization: { enabled: true, // Enable product quantization numSubvectors: 16, // Number of subvectors to split the vector into numCentroids: 256 // Number of centroids per subvector }, // Whether to use disk-based storage for the index useDiskBasedIndex: true // Enable disk-based storage }, // Storage configuration (required for disk-based index) storage: { // Choose appropriate storage for your environment requestPersistentStorage: true } }) // The optimized index automatically adapts based on dataset size: // 1. For small datasets: Uses standard in-memory approach // 2. For medium datasets: Applies product quantization to reduce memory usage // 3. For large datasets: Combines product quantization with disk-based storage // Check status to see memory usage and optimization details const status = await db.status() console.log(status.details.index) // Example output: // { // indexSize: 10000, // optimized: true, // memoryUsage: 536870912, // Memory usage in bytes // productQuantization: true, // diskBasedIndex: true // } ``` ## 🧪 Distance Functions - `cosineDistance` (default) - `euclideanDistance` - `manhattanDistance` - `dotProductDistance` ## 📤📥 Backup and Restore Brainy provides powerful backup and restore capabilities that allow you to: - Back up your data - Transfer data between Brainy instances - Restore existing data into Brainy for vectorization and indexing - Backup data for analysis or visualization in other tools ### Backing Up Data ```typescript // Backup all data from the database const backupData = await db.backup() // The backup data includes: // - All nouns (entities) with their vectors and metadata // - All verbs (relationships) between nouns // - Noun types and verb types // - HNSW index data for fast similarity search // - Version information // Save the backup data to a file (Node.js environment) import fs from 'fs' fs.writeFileSync('brainy-backup.json', JSON.stringify(backupData, null, 2)) ``` ### Restoring Data Brainy's restore functionality is flexible and can handle: 1. Complete backups with vectors and index data 2. Sparse data without vectors (vectors will be created during restore) 3. Data without HNSW index (index will be reconstructed if needed) ```typescript // Restore data with all options const restoreResult = await db.restore(backupData, { clearExisting: true // Whether to clear existing data before restore }) // Restore sparse data (without vectors) // Vectors will be automatically created using the embedding function const sparseData = { nouns: [ { id: '123', // No vector field - will be created during restore metadata: { noun: 'Thing', text: 'This text will be used to generate a vector' } } ], verbs: [], version: '1.0.0' } const sparseRestoreResult = await db.restore(sparseData) ``` ### CLI Backup/Restore ```bash # Backup data to a file brainy backup --output brainy-backup.json # Restore data from a file brainy restore --input brainy-backup.json --clear-existing # Restore sparse data (without vectors) brainy restore --input sparse-data.json ``` ## 🔋 Embedding Brainy uses the following embedding approach: - TensorFlow Universal Sentence Encoder (high-quality text embeddings) - Custom embedding functions can be plugged in for specialized domains ## 🧰 Extensions Brainy includes an augmentation system for extending functionality: - **Memory Augmentations**: Different storage backends - **Sense Augmentations**: Process raw data - **Cognition Augmentations**: Reasoning and inference - **Dialog Augmentations**: Text processing and interaction - **Perception Augmentations**: Data interpretation and visualization - **Activation Augmentations**: Trigger actions ## 🌐 Browser Compatibility Works in all modern browsers: - Chrome 86+ - Edge 86+ - Opera 72+ - Chrome for Android 86+ For browsers without OPFS support, falls back to in-memory storage. ## ☁️ Cloud Deployment Brainy can be deployed as a standalone web service on various cloud platforms using the included cloud wrapper: - **AWS Lambda and API Gateway**: Deploy as a serverless function with API Gateway - **Google Cloud Run**: Deploy as a containerized service - **Cloudflare Workers**: Deploy as a serverless function on the edge The cloud wrapper provides both RESTful and WebSocket APIs for all Brainy operations, enabling both request-response and real-time communication patterns. It supports multiple storage backends and can be configured via environment variables. Key features of the cloud wrapper: - RESTful API for standard CRUD operations - WebSocket API for real-time updates and subscriptions - Support for multiple storage backends (Memory, FileSystem, S3) - Configurable via environment variables - Deployment scripts for AWS, Google Cloud, and Cloudflare To get started with cloud deployment, see the [Cloud Wrapper README](cloud-wrapper/README.md). ## 🔗 Related Projects - **[Cartographer](https://github.com/sodal-project/cartographer)** - A companion project that provides standardized interfaces for interacting with Brainy ## 📚 Demo The repository includes a comprehensive demo that showcases Brainy's main features: - `examples/demo.html` - A single demo page with animations demonstrating Brainy's features. Run it with `npm run demo` (see [demo instructions](README.demo.md) for details): - How Brainy runs in different environments (browser, Node.js, server, cloud) - How the noun-verb data model works - How HNSW search works ### Syncing Brainy Instances You can use the conduit augmentations to sync Brainy instances: - **WebSocket iConduit**: For syncing between browsers and servers, or between servers (like a digital postal service with superpowers!). WebSockets cannot be used for direct browser-to-browser communication without a server in the middle. - **WebRTC iConduit**: For direct peer-to-peer syncing between browsers (like telepathy for your data, no middleman required!). This is the recommended approach for browser-to-browser communication. #### WebSocket Sync Example ```typescript import { BrainyData, augmentationPipeline, createConduitAugmentation } from '@soulcraft/brainy' // Create and initialize the database const db = new BrainyData() await db.init() // Create a WebSocket conduit augmentation const wsConduit = await createConduitAugmentation('websocket', 'my-websocket-sync') // Register the augmentation with the pipeline augmentationPipeline.register(wsConduit) // Connect to another Brainy instance (server or browser) // Replace the example URL below with your actual WebSocket server URL const connectionResult = await augmentationPipeline.executeConduitPipeline( 'establishConnection', ['wss://example-websocket-server.com/brainy-sync', {protocols: 'brainy-sync'}] ) if (connectionResult[0] && (await connectionResult[0]).success) { const connection = (await connectionResult[0]).data // Read data from the remote instance const readResult = await augmentationPipeline.executeConduitPipeline( 'readData', [{connectionId: connection.connectionId, query: {type: 'getAllNouns'}}] ) // Process and add the received data to the local instance if (readResult[0] && (await readResult[0]).success) { const remoteNouns = (await readResult[0]).data for (const noun of remoteNouns) { await db.add(noun.vector, noun.metadata) } } // Set up real-time sync by monitoring the stream await wsConduit.monitorStream(connection.connectionId, async (data) => { // Handle incoming data (e.g., new nouns, verbs, updates) if (data.type === 'newNoun') { await db.add(data.vector, data.metadata) } else if (data.type === 'newVerb') { await db.addVerb(data.sourceId, data.targetId, data.vector, data.options) } }) } ``` #### WebRTC Peer-to-Peer Sync Example ```typescript import { BrainyData, augmentationPipeline, createConduitAugmentation } from '@soulcraft/brainy' // Create and initialize the database const db = new BrainyData() await db.init() // Create a WebRTC conduit augmentation const webrtcConduit = await createConduitAugmentation('webrtc', 'my-webrtc-sync') // Register the augmentation with the pipeline augmentationPipeline.register(webrtcConduit) // Connect to a peer using a signaling server // Replace the example values below with your actual configuration const connectionResult = await augmentationPipeline.executeConduitPipeline( 'establishConnection', [ 'peer-id-to-connect-to', // Replace with actual peer ID { signalServerUrl: 'wss://example-signal-server.com', // Replace with your signal server localPeerId: 'my-local-peer-id', // Replace with your local peer ID iceServers: [{urls: 'stun:stun.l.google.com:19302'}] // Public STUN server } ] ) if (connectionResult[0] && (await connectionResult[0]).success) { const connection = (await connectionResult[0]).data // Set up real-time sync by monitoring the stream await webrtcConduit.monitorStream(connection.connectionId, async (data) => { // Handle incoming data (e.g., new nouns, verbs, updates) if (data.type === 'newNoun') { await db.add(data.vector, data.metadata) } else if (data.type === 'newVerb') { await db.addVerb(data.sourceId, data.targetId, data.vector, data.options) } }) // When adding new data locally, also send to the peer const nounId = await db.add("New data to sync", {noun: "Thing"}) // Send the new noun to the peer await augmentationPipeline.executeConduitPipeline( 'writeData', [ { connectionId: connection.connectionId, data: { type: 'newNoun', id: nounId, vector: (await db.get(nounId)).vector, metadata: (await db.get(nounId)).metadata } } ] ) } ``` #### Browser-Server Search Example Brainy supports searching a server-hosted instance from a browser, storing results locally, and performing further searches against the local instance: ```typescript import {BrainyData} from '@soulcraft/brainy' // Create and initialize the database with remote server configuration // Replace the example URL below with your actual Brainy server URL const db = new BrainyData({ remoteServer: { url: 'wss://example-brainy-server.com/ws', // Replace with your server URL protocols: 'brainy-sync', autoConnect: true // Connect automatically during initialization } }) await db.init() // Or connect manually after initialization if (!db.isConnectedToRemoteServer()) { // Replace the example URL below with your actual Brainy server URL await db.connectToRemoteServer('wss://example-brainy-server.com/ws', 'brainy-sync') } // Search the remote server (results are stored locally) const remoteResults = await db.searchText('machine learning', 5, {searchMode: 'remote'}) // Search the local database (includes previously stored results) const localResults = await db.searchText('machine learning', 5, {searchMode: 'local'}) // Perform a combined search (local first, then remote if needed) const combinedResults = await db.searchText('neural networks', 5, {searchMode: 'combined'}) // Add data to both local and remote instances const id = await db.addToBoth('Deep learning is a subset of machine learning', { noun: 'Concept', category: 'AI', tags: ['deep learning', 'neural networks'] }) // Clean up when done await db.shutDown() ``` For a complete demonstration of Brainy's features, see the [demo
