| # WebChat (Gateway WebSocket UI) |
|
|
| Status: the macOS/iOS SwiftUI chat UI talks directly to the Gateway WebSocket. |
|
|
| ## What it is |
|
|
| - A native chat UI for the gateway (no embedded browser and no local static server). |
| - Uses the same sessions and routing rules as other channels. |
| - Deterministic routing: replies always go back to WebChat. |
|
|
| ## Quick start |
|
|
| 1. Start the gateway. |
| 2. Open the WebChat UI (macOS/iOS app) or the Control UI chat tab. |
| 3. Ensure gateway auth is configured (required by default, even on loopback). |
|
|
| ## How it works (behavior) |
|
|
| - The UI connects to the Gateway WebSocket and uses `chat.history`, `chat.send`, and `chat.inject`. |
| - `chat.inject` appends an assistant note directly to the transcript and broadcasts it to the UI (no agent run). |
| - History is always fetched from the gateway (no local file watching). |
| - If the gateway is unreachable, WebChat is read-only. |
|
|
| ## Remote use |
|
|
| - Remote mode tunnels the gateway WebSocket over SSH/Tailscale. |
| - You do not need to run a separate WebChat server. |
|
|
| ## Configuration reference (WebChat) |
|
|
| Full configuration: [Configuration](/gateway/configuration) |
|
|
| Channel options: |
|
|
| - No dedicated `webchat.*` block. WebChat uses the gateway endpoint + auth settings below. |
|
|
| Related global options: |
|
|
| - `gateway.port`, `gateway.bind`: WebSocket host/port. |
| - `gateway.auth.mode`, `gateway.auth.token`, `gateway.auth.password`: WebSocket auth. |
| - `gateway.remote.url`, `gateway.remote.token`, `gateway.remote.password`: remote gateway target. |
| - `session.*`: session storage and main key defaults. |
