# Soulcraft Brainy
A combined Graph and Vector database that runs in a browser or Node.js and utilizes Origin Private File System (OPFS) for storage, with HNSW (Hierarchical Navigable Small World) for efficient vector indexing.
A combined Graph and Vector database that runs in a browser or Node.js and utilizes Origin Private File System (OPFS)
for storage, with HNSW (Hierarchical Navigable Small World) for efficient vector indexing.
## Features
- **Cross-platform**: Works in both browsers and Node.js
- **Persistent storage**: Uses Origin Private File System (OPFS) in browsers, with fallback to in-memory storage
- **Efficient vector search**: Implements HNSW (Hierarchical Navigable Small World) algorithm for fast approximate nearest neighbor search
- **Efficient vector search**: Implements HNSW (Hierarchical Navigable Small World) algorithm for fast approximate
nearest neighbor search
- **Automatic embedding**: Converts text and other data to vectors using embedding models
- **TensorFlow.js integration**: Uses Universal Sentence Encoder for high-quality text embeddings (TensorFlow.js is included as a dependency)
- **TensorFlow.js integration**: Uses Universal Sentence Encoder for high-quality text embeddings (TensorFlow.js is
included as a dependency)
- **Metadata support**: Store and retrieve metadata alongside vectors
- **TypeScript support**: Fully typed API with generics for metadata types
- **Multiple distance functions**: Supports cosine, Euclidean, Manhattan, and dot product distance metrics
- **Augmentation system**: Extensible architecture for adding specialized capabilities
- **Memory augmentation**: Store and retrieve data in different formats (fileSystem, in-memory, firestore)
- **Full graph database capabilities**: Structured representation of entities and relationships with support for nodes (nouns) and edges (verbs)
- **Full graph database capabilities**: Structured representation of entities and relationships with support for nodes (
nouns) and edges (verbs)

## Publishing and Using as a Private NPM Package
Soulcraft Brainy is configured as a private NPM package with restricted access. This section provides information on how to publish and use it within your organization.
### Versioning
This project uses semantic versioning (SemVer):
- **Major version** (`x.0.0`): Breaking changes that may require updates to dependent code
- **Minor version** (`0.x.0`): New features that don't break existing functionality
- **Patch version** (`0.0.x`): Bug fixes and other minor changes
The package includes scripts for manual version bumping:
```bash
# Increment patch version (0.0.x)
npm run version:patch
# Increment minor version (0.x.0)
npm run version:minor
# Increment major version (x.0.0)
npm run version:major
```
These commands will update the version in package.json and create a git tag for the new version.
### Publishing the Package
To publish updates to the package:
1. Ensure you have the appropriate npm credentials and access to the @soulcraft organization
2. Update the version using one of the version scripts:
```bash
npm run version:patch # For bug fixes and minor changes
npm run version:minor # For new features
npm run version:major # For breaking changes
```
3. Use the deploy script to build and publish the package:
```bash
npm run deploy
```
Alternatively, you can run the steps separately:
1. Build the package:
```bash
npm run build
```
2. Publish the package:
```bash
npm publish
```
Note that the package has the following configuration in package.json:
```json
"private": false,
"publishConfig": {
"access": "restricted"
}
```
This ensures that the package is only accessible to users with appropriate permissions within the @soulcraft organization. The `"access": "restricted"` setting limits access to the package to members of the @soulcraft organization, while `"private": false` allows the package to be published to npm.
### Installing the Private Package
To install the package in another project:
1. Ensure you have access to the @soulcraft organization on npm
2. Add the package to your project:
```bash
npm install @soulcraft/brainy
```
3. If you're using a private npm registry, you may need to configure npm to use your organization's registry:
```bash
npm config set @soulcraft:registry https://your-private-registry.com/
```
This approach allows you to use the augmentation interfaces in client applications that need to implement or interact
with Brainy's augmentation system.

##### FirestoreSync Conduit Augmentation
Brainy includes a FirestoreSync conduit augmentation that allows for syncing data to Firestore either one-way or
two-way:
- **One-way sync**: Data is only pushed from Brainy to Firestore
- **Two-way sync**: Data is synchronized between Brainy and Firestore in both directions
**Prerequisites:**
1. Install Firebase: `npm install firebase`
2. Set up a Firebase project and enable Firestore
3. Get your Firebase configuration from the Firebase console
**Usage:**
```typescript
import {
registerAugmentation,
initializeAugmentationPipeline,
createFirestoreSyncAugmentation,
FirestoreSyncConfig
} from '@soulcraft/brainy';
// Your Firebase configuration
const firebaseConfig = {
apiKey: "your-api-key",
authDomain: "your-project-id.firebaseapp.com",
projectId: "your-project-id",
storageBucket: "your-project-id.appspot.com",
messagingSenderId: "your-messaging-sender-id",
appId: "your-app-id"
};
// Create the FirestoreSync augmentation with one-way sync configuration
const oneWaySyncConfig: FirestoreSyncConfig = {
firebaseConfig,
nodesCollection: 'brainy_nodes',
edgesCollection: 'brainy_edges',
metadataCollection: 'brainy_metadata',
syncMode: 'one-way'
};
// Create and register the augmentation
const firestoreSync = createFirestoreSyncAugmentation(
'brainy-firestore-sync',
oneWaySyncConfig
);
registerAugmentation(firestoreSync);
// Initialize the augmentation pipeline
initializeAugmentationPipeline();
// Initialize the augmentation
await firestoreSync.initialize();
// Now you can use the augmentation to sync data
// For example, to sync a node to Firestore:
await firestoreSync.syncNodeToFirestore(node);
// Or to sync an edge to Firestore:
await firestoreSync.syncEdgeToFirestore(edge);
// Or to sync metadata to Firestore:
await firestoreSync.syncMetadataToFirestore('metadata-id', { key: 'value' });
// You can also use the standard conduit methods:
// Read data from Firestore
const response = await firestoreSync.readData({
collection: 'brainy_nodes',
id: 'node-id'
});
// Write data to Firestore
await firestoreSync.writeData({
collection: 'custom_collection',
id: 'custom-doc-1',
document: {
name: 'Custom Document',
timestamp: new Date()
}
});
// Monitor changes in Firestore
await firestoreSync.monitorStream('brainy_nodes', (data) => {
console.log('Node change detected:', data);
});
// When done, shut down the augmentation
await firestoreSync.shutDown();
```
**Two-way Sync Configuration:**
For two-way synchronization between Brainy and Firestore:
```typescript
const twoWaySyncConfig: FirestoreSyncConfig = {
firebaseConfig,
nodesCollection: 'brainy_nodes',
edgesCollection: 'brainy_edges',
metadataCollection: 'brainy_metadata',
syncMode: 'two-way',
syncInterval: 30000 // Sync every 30 seconds
};
const twoWaySync = createFirestoreSyncAugmentation(
'brainy-firestore-two-way-sync',
twoWaySyncConfig
);
```

- Better performance as augmentations are available immediately at startup
- Improved tree-shaking and bundle optimization
- Type safety and better IDE support
- No need for dynamic imports or async loading
