ai.matey.backend.browser

Browser-compatible backend adapters for AI Matey - Universal AI Adapter System.

Part of the ai.matey monorepo.

Installation

npm install ai.matey.backend.browser

Overview

This package contains backend adapters that can run natively in browser environments without Node.js dependencies:

• Chrome AI - Chrome's built-in AI APIs (window.ai)
• Function - Custom function-based backends for testing and integration
• Mock - Mock responses for testing and development

For server-side provider adapters (OpenAI, Anthropic, etc.), see ai.matey.backend.

Usage

Chrome AI Adapter

import { ChromeAIBackendAdapter } from 'ai.matey.backend.browser';

// Chrome AI is available in Chrome 129+ with AI features enabled
const chromeAI = new ChromeAIBackendAdapter();

// Check availability
const isAvailable = await chromeAI.healthCheck();

Function Backend

import { FunctionBackendAdapter, createFunctionBackend } from 'ai.matey.backend.browser';

// Create a custom backend from a function
const customBackend = createFunctionBackend(async (request) => ({
  message: { role: 'assistant', content: 'Hello from custom backend!' },
  finishReason: 'stop',
  metadata: { requestId: request.metadata.requestId, provenance: {} },
}));

Mock Backend

import { MockBackendAdapter, createEchoBackend } from 'ai.matey.backend.browser';

// Create a mock backend for testing
const mockBackend = new MockBackendAdapter({
  defaultResponse: 'This is a test response',
});

// Or use the echo helper
const echoBackend = createEchoBackend();
