# Brainy Augmentations
</div>
This directory contains the augmentation implementations for Brainy. Augmentations are pluggable components that extend
Brainy's functionality in various ways.
## Available Augmentations
### Conduit Augmentations
Conduit augmentations provide data synchronization between Brainy instances.
#### WebSocketConduitAugmentation
A conduit augmentation that syncs Brainy instances using WebSockets. This is used for syncing between browsers and
servers, or between servers.
```javascript
import { createConduitAugmentation, augmentationPipeline } from '@soulcraft/brainy'
// 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
const connectionResult = await wsConduit.establishConnection(
'wss://your-websocket-server.com/brainy-sync',
{ protocols: 'brainy-sync' }
)
```
#### WebRTCConduitAugmentation
A conduit augmentation that syncs Brainy instances using WebRTC. This is used for direct peer-to-peer syncing between
browsers.
```javascript
import { createConduitAugmentation, augmentationPipeline } from '@soulcraft/brainy'
// 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
const connectionResult = await webrtcConduit.establishConnection(
'peer-id-to-connect-to',
{
signalServerUrl: 'wss://your-signal-server.com',
localPeerId: 'my-peer-id',
iceServers: [{ urls: 'stun:stun.l.google.com:19302' }]
}
)
```
#### ServerSearchConduitAugmentation
A specialized conduit augmentation that provides functionality for searching a server-hosted Brainy instance and storing
results locally. This allows you to:
- Search a server-hosted Brainy instance from a browser
- Store the search results in a local Brainy instance
- Perform further searches against the local instance without needing to query the server again
- Add data to both local and server instances
```javascript
import {
ServerSearchConduitAugmentation,
createServerSearchAugmentations,
augmentationPipeline
} from '@soulcraft/brainy'
// Using the factory function (recommended)
const { conduit, activation, connection } = await createServerSearchAugmentations(
'wss://your-brainy-server.com/ws',
{ protocols: 'brainy-sync' }
)
// Register the augmentations with the pipeline
augmentationPipeline.register(conduit)
augmentationPipeline.register(activation)
// Search the server and store results locally
const serverSearchResult = await conduit.searchServer(
connection.connectionId,
'your search query',
5 // limit
)
// Search the local instance
const localSearchResult = await conduit.searchLocal('your search query', 5)
// Perform a combined search (local first, then server if needed)
const combinedSearchResult = await conduit.searchCombined(
connection.connectionId,
'your search query',
5
)
// Add data to both local and server
const addResult = await conduit.addToBoth(
connection.connectionId,
'Text to add',
{ /* metadata */ }
)
```
### Activation Augmentations
Activation augmentations dictate how Brainy initiates actions, responses, or data manipulations.
#### ServerSearchActivationAugmentation
An activation augmentation that provides actions for server search functionality. This works in conjunction with the
ServerSearchConduitAugmentation to provide a complete solution for browser-server search.
```javascript
import {
ServerSearchActivationAugmentation,
createServerSearchAugmentations,
augmentationPipeline
} from '@soulcraft/brainy'
// Using the factory function (recommended)
const { conduit, activation, connection } = await createServerSearchAugmentations(
'wss://your-brainy-server.com/ws',
{ protocols: 'brainy-sync' }
)
// Register the augmentations with the pipeline
augmentationPipeline.register(conduit)
augmentationPipeline.register(activation)
// Use the activation augmentation to search the server
const serverSearchAction = activation.triggerAction('searchServer', {
connectionId: connection.connectionId,
query: 'your search query',
limit: 5
})
if (serverSearchAction.success) {
// The data property contains a promise that will resolve to the search results
const serverSearchResult = await serverSearchAction.data
console.log('Server search results:', serverSearchResult)
}
// Other available actions:
// - 'connectToServer': Connect to a server
// - 'searchLocal': Search the local instance
// - 'searchCombined': Search both local and server
// - 'addToBoth': Add data to both local and server
```
## Using the Augmentation Pipeline
The augmentation pipeline provides a way to execute augmentations based on their type.
```javascript
import { augmentationPipeline } from '@soulcraft/brainy'
// Execute a conduit augmentation
const conduitResults = await augmentationPipeline.executeConduitPipeline(
'methodName',
[arg1, arg2, ...],
{ /* options */ }
)
// Execute an activation augmentation
const activationResults = await augmentationPipeline.executeActivationPipeline(
'methodName',
[arg1, arg2, ...],
{ /* options */ }
)
```
## Creating Custom Augmentations
To create a custom augmentation, implement one of the augmentation interfaces:
- `ISenseAugmentation`: For processing raw data
- `IConduitAugmentation`: For data synchronization
- `ICognitionAugmentation`: For reasoning and inference
- `IMemoryAugmentation`: For data storage
- `IPerceptionAugmentation`: For data interpretation and visualization
- `IDialogAugmentation`: For natural language processing
- `IActivationAugmentation`: For triggering actions
Example:
```javascript
import { AugmentationType, IActivationAugmentation } from '@soulcraft/brainy'
class MyCustomActivation implements IActivationAugmentation {
readonly
name = 'my-custom-activation'
readonly
description = 'My custom activation augmentation'
enabled = true
getType(): AugmentationType {
return AugmentationType.ACTIVATION
}
async initialize(): Promise<void> {
// Initialization code
}
async shutDown(): Promise<void> {
// Cleanup code
}
async getStatus(): Promise<'active' | 'inactive' | 'error'> {
return 'active'
}
triggerAction(actionName: string, parameters
?:
Record<string, unknown>
):
AugmentationResponse<unknown> {
// Implementation
}
generateOutput(knowledgeId: string, format: string): AugmentationResponse<string | Record<string, unknown
>> {
// Implementation
}
interactExternal(systemId
:
string, payload
:
Record < string, unknown >
):
AugmentationResponse < unknown > {
// Implementation
}
}
```
