🔧 Installation

npm install @soulcraft/brainy

TensorFlow.js packages are included as required dependencies and will be automatically installed. If you encounter dependency conflicts, you may need to use the --legacy-peer-deps flag:

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

🏁 Quick Start

Brainy uses a unified build that automatically adapts to your environment (Node.js, browser, or serverless):

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)

// Add a relationship between items
await db.addVerb(catId, dogId, {
  verb: VerbType.RelatedTo,
  description: 'Both are common household pets'
})

Import Options

// Standard import - automatically adapts to any environment
import { BrainyData } from '@soulcraft/brainy'

// Minified version for production
import { BrainyData } from '@soulcraft/brainy/min'

Browser Usage

<script type="module">
  // Use the CDN to load the unified build
  import { BrainyData } from 'https://cdn.jsdelivr.net/npm/@soulcraft/brainy/dist/unified.js'

  // Or minified version
  // import { BrainyData } from 'https://cdn.jsdelivr.net/npm/@soulcraft/brainy/dist/unified.min.js'

  const db = new BrainyData()
  await db.init()
  // ...
</script>

Modern bundlers like Webpack, Rollup, and Vite will automatically use the unified build which adapts to any environment.

🧩 How It Works

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
2. HNSW Algorithm - Enables fast similarity search through a hierarchical graph structure
3. Adaptive Environment Detection - Automatically senses your platform and optimizes accordingly:
   • Detects browser, Node.js, and serverless environments
   • Adjusts performance parameters based on available resources
   • Learns from query patterns to optimize future searches
   • Tunes itself for your specific use cases
4. Intelligent Storage Selection - Uses the best available storage option for your environment:
   • Browser: Origin Private File System (OPFS)
   • Node.js: File system
   • Server: S3-compatible storage (optional)
   • Serverless: In-memory storage with optional cloud persistence
   • Fallback: In-memory storage
   • Automatically migrates between storage types as needed

🚀 The Brainy Pipeline

Brainy's data processing pipeline transforms raw data into searchable, connected knowledge that gets smarter over time:

Raw Data → Embedding → Vector Storage → Graph Connections → Adaptive Learning → Query & Retrieval

Each time data flows through this pipeline, Brainy learns more about your usage patterns and environment, making future operations faster and more relevant.

Pipeline Stages

1. Data Ingestion

   • Raw text or pre-computed vectors enter the pipeline
   • Data is validated and prepared for processing

2. Embedding Generation

   • Text is transformed into numerical vectors using embedding models
   • Uses TensorFlow Universal Sentence Encoder for high-quality text embeddings
   • Custom embedding functions can be plugged in for specialized domains

3. Vector Indexing

   • Vectors are indexed using the HNSW algorithm
   • Hierarchical structure enables fast similarity search
   • Configurable parameters for precision vs. performance tradeoffs

4. Graph Construction

   • Nouns (entities) become nodes in the knowledge graph
   • Verbs (relationships) connect related entities
   • Typed relationships add semantic meaning to connections

5. Adaptive Learning

   • Analyzes usage patterns to optimize future operations
   • Tunes performance parameters based on your environment
   • Adjusts search strategies based on query history
   • Becomes more efficient and relevant the more you use it

6. Intelligent Storage

   • Data is saved using the optimal storage for your environment
   • Automatic selection between OPFS, filesystem, S3, or memory
   • Migrates between storage types as your application's needs evolve
   • Scales from tiny datasets to massive data collections
   • Configurable storage adapters for custom persistence needs

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 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
     • WebRTC iConduit - Direct peer-to-peer syncing between browsers
   • 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:

// 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:

# 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"}'

        // }
    }
})

Optimized HNSW for Large Datasets

Brainy includes an optimized HNSW index implementation for large datasets that may not fit entirely in memory, using a hybrid approach:

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

import { BrainyData } from '@soulcraft/brainy'

// Configure with optimized HNSW index for large datasets
const db = new BrainyData({
    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: {
        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)

Distance Functions

• cosineDistance (default)
• euclideanDistance
• manhattanDistance
• dotProductDistance

Backup and Restore

Brainy provides 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

// 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 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)

// Restore data with all options
const restoreResult = await db.restore(backupData, {
  clearExisting: true // Whether to clear existing data before restore
})

// Import 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 import
      metadata: {
        noun: 'Thing',
        text: 'This text will be used to generate a vector'
      }
    }
  ],
  verbs: [],
  version: '1.0.0'
}

const sparseImportResult = await db.importSparseData(sparseData)

CLI Backup/Restore

# Backup data to a file
brainy backup --output brainy-backup.json

# Restore data from a file
brainy restore --input brainy-backup.json --clear-existing

# Import sparse data (without vectors)
brainy import-sparse --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

Simplified Augmentation System

Brainy provides a simplified factory system for creating, importing, and executing augmentations with minimal boilerplate:

import {
  createMemoryAugmentation,
  createConduitAugmentation,
  createSenseAugmentation,
  addWebSocketSupport,
  executeStreamlined,
  processStaticData,
  processStreamingData,
  createPipeline
} from '@soulcraft/brainy'

// Create a memory augmentation with minimal code
const memoryAug = createMemoryAugmentation({
  name: 'simple-memory',
  description: 'A simple in-memory storage augmentation',
  autoRegister: true,
  autoInitialize: true,

  // Implement only the methods you need
  storeData: async (key, data) => {
    // Your implementation here
    return {
      success: true,
      data: true
    }
  },

  retrieveData: async (key) => {
    // Your implementation here
    return {
      success: true,
      data: { example: 'data', key }
    }
  }
})

// Add WebSocket support to any augmentation
const wsAugmentation = addWebSocketSupport(memoryAug, {
  connectWebSocket: async (url) => {
    // Your implementation here
    return {
      connectionId: 'ws-1',
      url,
      status: 'connected'
    }
  }
})

// Process static data through a pipeline
const result = await processStaticData(
  'Input data',
  [
    {
      augmentation: senseAug,
      method: 'processRawData',
      transformArgs: (data) => [data, 'text']
    },
    {
      augmentation: memoryAug,
      method: 'storeData',
      transformArgs: (data) => ['processed-data', data]
    }
  ]
)

// Create a reusable pipeline
const pipeline = createPipeline([
  {
    augmentation: senseAug,
    method: 'processRawData',
    transformArgs: (data) => [data, 'text']
  },
  {
    augmentation: memoryAug,
    method: 'storeData',
    transformArgs: (data) => ['processed-data', data]
  }
])

// Use the pipeline
const result = await pipeline('New input data')

// Dynamically load augmentations at runtime
const loadedAugmentations = await loadAugmentationModule(
  import('./my-augmentations.js'),
  {
    autoRegister: true,
    autoInitialize: true
  }
)

The simplified augmentation system provides:

1. Factory Functions - Create augmentations with minimal boilerplate
2. WebSocket Support - Add WebSocket capabilities to any augmentation
3. Streamlined Pipeline - Process data through augmentations more efficiently
4. Dynamic Loading - Load augmentations at runtime when needed
5. Static & Streaming Data - Handle both static and streaming data with the same API

For a complete example, see examples/simplified-augmentations.js.

Model Control Protocol (MCP)

Brainy includes a Model Control Protocol (MCP) implementation that allows external models to access Brainy data and use the augmentation pipeline as tools:

• BrainyMCPAdapter: Provides access to Brainy data through MCP
• MCPAugmentationToolset: Exposes the augmentation pipeline as tools
• BrainyMCPService: Integrates the adapter and toolset, providing WebSocket and REST server implementations

Environment compatibility:

• BrainyMCPAdapter and MCPAugmentationToolset can run in any environment (browser, Node.js, server)
• BrainyMCPService core functionality works in any environment, but server functionality (WebSocket/REST) is in the cloud-wrapper project

For detailed documentation and usage examples, see the MCP documentation.

Cross-Environment Compatibility

Brainy is designed to run seamlessly in any environment, from browsers to Node.js to serverless functions and containers. All Brainy data, functions, and augmentations are environment-agnostic, allowing you to use the same code everywhere.

Environment Detection

Brainy automatically detects the environment it's running in:

import { environment } from '@soulcraft/brainy'

// Check which environment we're running in
console.log(`Running in ${
  environment.isBrowser ? 'browser' : 
  environment.isNode ? 'Node.js' : 
  'serverless/unknown'
} environment`)

Adaptive Storage

Storage adapters are automatically selected based on the environment:

• Browser: Uses Origin Private File System (OPFS) when available, falls back to in-memory storage
• Node.js: Uses file system storage by default, with options for S3-compatible cloud storage
• Serverless: Uses in-memory storage with options for cloud persistence
• Container: Automatically detects and uses the appropriate storage based on available capabilities

Dynamic Imports

Brainy uses dynamic imports to load environment-specific dependencies only when needed, keeping the bundle size small and ensuring compatibility across environments.

Browser Support

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
• Model Control Protocol (MCP) service for external model access
• Support for multiple storage backends (Memory, FileSystem, S3)
• Configurable via environment variables
• Deployment scripts for AWS, Google Cloud, and Cloudflare

Deploying to the Cloud

You can deploy the cloud wrapper to various cloud platforms using the following npm scripts from the root directory:

# Deploy to AWS Lambda and API Gateway
npm run deploy:cloud:aws

Syncing Brainy Instances

You can use the conduit augmentations to sync Brainy instances:

• WebSocket iConduit: For syncing between browsers and servers, or between servers. 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. This is the recommended approach for browser-to-browser communication.

WebSocket Sync Example

import {
    BrainyData,
    pipeline,
    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
pipeline.register(wsConduit)

// Connect to another Brainy instance (server or browser)
// Replace the example URL below with your actual WebSocket server URL
const connectionResult = await pipeline.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 pipeline.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

import {
    BrainyData,
    pipeline,
    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
pipeline.register(webrtcConduit)

// Connect to a peer using a signaling server
// Replace the example values below with your actual configuration
const connectionResult = await pipeline.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 pipeline.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:

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()
