with-browser-extension

A Chrome extension that hosts an assistant-ui chat interface in a browser side panel.

Uses useExternalStoreRuntime with mock messages to demonstrate the UI without a backend. Swap in your own runtime (Cloud, AI SDK, etc.) for real AI responses.

Getting Started

  1. Install dependencies from the monorepo root:

    pnpm install
    
  2. Build the extension:

    cd examples/with-browser-extension
    pnpm build
    
  3. Load into Chrome:

    • Open chrome://extensions
    • Enable Developer mode (top right)
    • Click Load unpacked
    • Select the dist/ folder
  4. Click the extension icon in the toolbar. The side panel opens with the chat UI.

Development

pnpm dev

This watches for TypeScript and CSS changes. After each rebuild, reload the extension in chrome://extensions (click the refresh icon on the extension card).

Connecting a Real Backend

Replace useMockStore() in sidepanel.tsx with a real runtime. Since the extension runs client-side, you'll need to point to an external API endpoint rather than a local route handler.
