# pico-echo-server Minimal Pico Protocol WebSocket server for testing the `pico_client` channel. ## Usage ```bash go run ./examples/pico-echo-server -addr :9090 -token secret ``` ### Flags | Flag | Default | Description | |----------|---------|------------------------------------| | `-addr` | `:9090` | Listen address | | `-token` | (none) | Auth token; empty disables auth | ## How it works - Listens for WebSocket connections at `/ws` - Authenticates via `Authorization: Bearer ` header or `?token=` query param - Prints received `message.send` content to stdout - Responds to `ping` with `pong` - Lines typed into stdin are broadcast as `message.create` to all connected clients ## Testing with pico_client 1. Start the server: ```bash go run ./examples/pico-echo-server -token mytoken ``` 2. Configure `pico_client` in your `config.json`: ```json { "channel_list": { "pico_client": { "enabled": true, "url": "ws://localhost:9090/ws", "token": "mytoken", "session_id": "test-session" } } } ``` 3. Start picoclaw — the client connects and you can exchange messages interactively via stdin/stdout.
