# Forever Bridge — Google Chat via Pub/Sub
|
|
|
|
Zero-dependency Node.js service that runs Gemini CLI in forever mode on a GCE
|
|
VM, receiving Google Chat messages via Cloud Pub/Sub and responding via Chat
|
|
REST API.
|
|
|
|
**No `npm install` needed.** Auth uses the GCE metadata server; Pub/Sub and Chat
|
|
use raw REST APIs. Just `node main.mjs`.
|
|
|
|
## Architecture
|
|
|
|
```
|
|
Google Chat Space
|
|
↓ Pub/Sub topic
|
|
Cloud Pub/Sub (pull)
|
|
↓
|
|
main.mjs (poll loop)
|
|
├── process-manager.mjs → npx gemini-cli --forever -r -y -m gemini-3-flash-preview
|
|
│ └── A2A JSON-RPC on localhost:3100
|
|
└── Chat REST API → Google Chat Space (response)
|
|
```
