A powerful, lightweight vector & graph database for browsers and Node.js

✨ Overview

Say hello to Brainy, your new favorite data sidekick! 🎉 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.

🚀 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)

📊 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!)

🔧 Installation

Due to a dependency conflict between TensorFlow.js packages, use the --legacy-peer-deps flag when installing:

npm install @soulcraft/brainy --legacy-peer-deps

🏁 Quick Start

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!

🚀 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)
   • 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 🔍

   • 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
   • 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 🔌

   • 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 })

🏃‍♀️ Running the Pipeline

The pipeline runs automatically when you:

// 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:

# 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 <sourceId> <targetId> RelatedTo

🔧 Extending the Pipeline

Brainy's pipeline is designed for extensibility at every stage:

1. Custom Embedding 🧩

   // 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 📏

   // 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 📦

   // 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 🧠

   // 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:

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

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)
        }
    })
}

// 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

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:

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.

Code Style Guidelines

Brainy follows a specific code style to maintain consistency throughout the codebase:

1. No Semicolons: All code in the project should avoid using semicolons wherever possible. This applies to:

   • Source code files (.ts, .js)
   • Generated code
   • Code examples in documentation
   • Templates and snippets

2. Formatting: The project uses Prettier for code formatting with the following settings:

   • No semicolons ("semi": false)
   • Single quotes for strings ("singleQuote": true)
   • 2-space indentation ("tabWidth": 2)
   • Always use parentheses around arrow function parameters ("arrowParens": "always")
   • Place the closing bracket of JSX elements on the same line ("bracketSameLine": true)
   • Add spaces between brackets and object literals ("bracketSpacing": true)
   • Line width of 80 characters ("printWidth": 80)
   • No trailing commas ("trailingComma": "none")
   • Use spaces instead of tabs ("useTabs": false)

3. Linting: ESLint is configured with the following rules:

   • No semicolons:

     "semi": ["error", "never"],
     "@typescript-eslint/semi": ["error", "never"]
     

   • Unused variables handling:

     "no-unused-vars": "off",
     "@typescript-eslint/no-unused-vars": ["warn", {
       "args": "after-used",
       "argsIgnorePattern": "^_"
     }]
     

   • Extends recommended ESLint and TypeScript ESLint configurations

4. TypeScript Configuration:

   • Strict type checking enabled ("strict": true)
   • Consistent casing in file names enforced ("forceConsistentCasingInFileNames": true)
   • ES2020 target with Node.js module system
   • Source maps generated for debugging

5. Commit Messages:

   • Use the imperative mood ("Add feature" not "Added feature")
   • Keep the first line concise (under 50 characters)
   • Reference issues and pull requests where appropriate
   • Provide detailed explanations in the commit body when necessary

When contributing to the project, please ensure your code follows these guidelines. The project's CI/CD pipeline will automatically check for style violations.
