nanobot-channel-web

A WebChannel plugin for nanobot that exposes chat APIs and validates tokens via an external auth service.

Features

POST /message to send user text into nanobot
GET /events/{chat_id} Server-Sent Events stream for assistant replies
GET /history/{chat_id} quick history for page refresh
GET /health health check
Optional external auth (authEnabled=true + authServiceUrl)
Optional apiToken fallback (Bearer header; SSE also supports ?token=)

Install

Install in the same Python environment as nanobot:

cd nanobot-channel-web
pip install -e .

Confirm plugin discovery:

nanobot plugins list

You should see web from plugin source.

Config

Run nanobot onboard once after plugin installation to inject defaults, then edit ~/.nanobot/config.json:

{
  "channels": {
    "web": {
      "enabled": true,
      "host": "127.0.0.1",
      "port": 9000,
      "allowFrom": ["*"],
      "apiToken": "change-this-token",
      "authEnabled": true,
      "authServiceUrl": "http://127.0.0.1:9100",
      "authServiceTimeoutS": 8,
      "corsOrigin": "*",
      "historySize": 200,
      "pingIntervalS": 15
    }
  }
}

If authEnabled is true, WebChannel validates bearer tokens by calling:

GET {authServiceUrl}/auth/me

Expected response shape:

{
  "ok": true,
  "user": {"id": 1, "phone": "13800000000"}
}

apiToken is used only when authEnabled is false.

Protected chat endpoints:

POST /message
GET /history/{chat_id}
GET /events/{chat_id}

Use header for normal requests:

Authorization: Bearer change-this-token

For native browser EventSource, use query param:

/events/web-user?token=change-this-token

Run

nanobot gateway

Then point your frontend to http://127.0.0.1:9000.
