## ✨ Overview Say hello to Brainy, your new favorite data sidekick! πŸŽ‰ Brainy combines the power of vector search with graph relationships in a lightweight, cross-platform database that's as smart as it is fun to use. Whether you're building AI applications, recommendation systems, or knowledge graphs, Brainy provides the tools you need to store, connect, and retrieve your data intelligently. What makes Brainy special? It intelligently adapts to you and your environment! Like a chameleon with a PhD, Brainy automatically detects your platform, adjusts its storage strategy, and optimizes performance based on your usage patterns. The more you use it, the smarter it gets - learning from your data to provide increasingly relevant results and connections. ### πŸš€ Key Features - **Vector Search** - Find semantically similar content using embeddings (like having ESP for your data!) - **Graph Relationships** - Connect data with meaningful relationships (your data's social network) - **Streaming Pipeline** - Process data in real-time as it flows through the system (like a data waterslide!) - **Extensible Augmentations** - Customize and extend functionality with pluggable components (LEGO blocks for your data!) - **Built-in Conduits** - Sync and scale across instances with WebSocket and WebRTC (your data's teleportation system!) - **LLM Creation & Training** - Build, train, and deploy language models from your graph data (your own personal AI factory!) - **Adaptive Intelligence** - Automatically optimizes for your environment and usage patterns - **Cross-Platform** - Works everywhere you do: browsers, Node.js, and server environments - **Persistent Storage** - Data persists across sessions and scales to any size (no memory loss here, even for elephant-sized data!) - **TypeScript Support** - Fully typed API with generics (for those who like their code tidy) - **CLI Tools** - Powerful command-line interface for data management (command line wizardry) ## πŸ“Š What Can You Build? (The Fun Stuff!) - **Semantic Search Engines** - Find content based on meaning, not just keywords (mind-reading for your data!) - **Recommendation Systems** - Suggest similar items based on vector similarity (like a friend who really gets your taste) - **Knowledge Graphs** - Build connected data structures with relationships (your data's family tree) - **AI Applications** - Store and retrieve embeddings for machine learning models (brain food for your AI) - **Custom Language Models** - Create, train, and deploy LLMs from your graph data (your personal GPT factory!) - **Data Organization Tools** - Automatically categorize and connect related information (like having a librarian in your code) - **Adaptive Experiences** - Create applications that learn and evolve with your users (digital chameleons!) ## πŸ”§ Installation Due to a dependency conflict between TensorFlow.js packages, use the `--legacy-peer-deps` flag when installing: ```bash npm install @soulcraft/brainy --legacy-peer-deps ``` ## 🏁 Quick Start ```typescript import {BrainyData, NounType, VerbType} from '@soulcraft/brainy' // 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' }) ``` ## 🧩 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! ## πŸš€ 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 β†’ Embedding β†’ Vector Storage β†’ Graph Connections β†’ Adaptive Learning β†’ 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! ### πŸ”„ 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 β†’ math magic) - Choose between TensorFlow Universal Sentence Encoder (high quality) or Simple Embedding (faster) - Custom embedding functions can be plugged in for specialized domains (bring your own secret sauce) 3. **Vector Indexing** πŸ” - 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** πŸ•ΈοΈ - 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** πŸ’Ύ - 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** πŸ‘οΈ - 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** πŸ’Ύ - 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 - Creates and trains language models from graph data - Examples: - Inferring new connections between existing data - Building custom LLMs from your nouns and verbs 4. **CONDUIT** πŸ”Œ - 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** πŸ” - Interprets, contextualizes, and visualizes identified nouns and verbs - Creates meaningful representations of data - Example: Generating visualizations of graph relationships 7. **DIALOG** πŸ’¬ - 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** πŸ”„ - 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** πŸ“‘ - 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 })` ### πŸƒβ€β™€οΈ Running the Pipeline The pipeline runs automatically when you: ```typescript // Add data (runs embedding β†’ indexing β†’ storage) const id = await db.add("Your text data here", {metadata}) // Search (runs embedding β†’ similarity search) const results = await db.searchText("Your query here", 5) // Connect entities (runs graph construction β†’ 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 ``` ### πŸ”§ 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** πŸ“ ```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** πŸ“¦ ```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) ``` ## πŸ“ 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 ## πŸ–₯️ 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 ``` ### πŸ”„ 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 ``` ### πŸ” Available Commands #### Basic Database Operations: -

**Memory Augmentations**: Different storage backends - **Sense Augmentations**: Process raw data - **Cognition Augmentations**: Reasoning and inference - **Dialog Augmentations**: Natural language processing - **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). ## πŸ”— Related Projects - **[sodal-project cartographer](https://github.com/sodal-project/cartographer)** - The defacto standard for interacting with Brainy ## πŸ“š Examples The repository includes several examples: - Web demo: `examples/demo.html` - Basic usage: `examples/basicUsage.js` - Custom storage: `examples/customStorage.js` - Memory augmentations: `examples/memoryAugmentationExample.js` - Conduit augmentations: `examples/conduitAugmentationExample.js` - Browser-server search: `examples/browser-server-search/` - Search a server-hosted Brainy instance from a browser ### 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) const connectionResult = await augmentationPipeline.executeConduitPipeline( 'establishConnection', ['wss://your-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 const connectionResult = await augmentationPipeline.executeConduitPipeline( 'establishConnection', [ 'peer-id-to-connect-to', { signalServerUrl: 'wss://your-signal-server.com', localPeerId: 'my-peer-id', iceServers: [{urls: 'stun:stun.l.google.com:19302'}] } ] ) 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 const db = new BrainyData({ remoteServer: { url: 'wss://your-brainy-server.com/ws', protocols: 'brainy-sync', autoConnect: true // Connect automatically during initialization } }) await db.init() // Or connect manually after initialization if (!db.isConnectedToRemoteServer()) { await db.connectToRemoteServer('wss://your-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 example with HTML interface, see the [browser-server-search example](examples/browser-server-search/). ## πŸ“‹ Requirements -
