# Chat Contributions
Extensions can add a chat interface to Superset by registering a trigger and a panel. The host owns the layout, open/close state, and display mode — the extension only needs to provide the UI components.
## Overview
A chat registration consists of two React components:
| Component | Role |
| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Trigger** | Always-visible entry point (e.g., a floating button). Rendered in the bottom-right corner in floating mode, or as a fixed overlay in panel mode. |
| **Panel** | The chat UI itself (message list, input, etc.). Mounted by the host in the active display mode. |
## Display Modes
The host supports two display modes, switchable by the user or the extension at runtime:
| Mode | Behavior |
| ---------- | ------------------------------------------------------------------------------------------------------------- |
| `floating` | Panel floats above page content, anchored to the bottom-right corner. |
| `panel` | Panel is docked to the right side of the application as a resizable sidebar, sitting beside the page content. |
The user's last selected mode and open/closed state are persisted across page reloads.
## Registering a Chat
Call `chat.registerChat` from your extension's entry point with a descriptor, a trigger factory, and a panel factory:
```tsx
import { chat } from '@apache-superset/core';
import ChatTrigger from './ChatTrigger';
import ChatPanel from './ChatPanel';
chat.registerChat(
{ id: 'my-org.my-chat', name: 'My Chat' },
ChatTrigger,
ChatPanel,
);
```
Only one chat registration is active at a time. If a second extension calls `registerChat`, it replaces the first and a warning is logged.
## Opening and Closing the Chat
The trigger component is responsible for toggling the panel. Use `chat.isOpen()`, `chat.open()`, and `chat.close()` to control visibility:
```tsx
import { chat } from '@apache-superset/core';
export default function ChatTrigger() {
return (
<button onClick={() => (chat.isOpen() ? chat.close() : chat.open())}>
💬
</button>
);
}
```
You can also subscribe to open/close events from any component:
```tsx
useEffect(() => {
const { dispose } = chat.onDidOpen(() => console.log('chat opened'));
return dispose;
}, []);
```
## Changing the Display Mode
Call `chat.setDisplayMode` to switch between `'floating'` and `'panel'` modes. In your panel component, subscribe to `onDidChangeDisplayMode` to react to changes (including those triggered by the user):
```tsx
import { useState, useEffect } from 'react';
import { chat } from '@apache-superset/core';
export default function ChatPanel() {
const [mode, setMode] = useState(chat.getDisplayMode());
useEffect(() => {
const { dispose } = chat.onDidChangeDisplayMode(m => setMode(m));
return dispose;
}, []);
return (
<div style={{ height: mode === 'panel' ? '100%' : '80vh' }}>
<button
onClick={() =>
chat.setDisplayMode(mode === 'panel' ? 'floating' : 'panel')
}
>
{mode === 'panel' ? 'Float' : 'Dock'}
</button>
{/* message list and input */}
</div>
);
}
```
## Chat API Reference
All methods are available on the `chat` namespace from `@apache-superset/core`:
| Method / Event | Description |
| ------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------- |
| `registerChat(descriptor, trigger, panel)` | Register a chat extension. Returns a `Disposable` to unregister. |
| `open()` | Open the chat panel. No-op if already open or no registration. |
| `close()` | Close the chat panel. |
| `isOpen()` | Returns `true` if the panel is currently open. |
| `getDisplayMode()` | Returns the current display mode (`'floating'` or `'panel'`). |
| `setDisplayMode(mode)` | Switch between `'floating'` and `'panel'` mode. |
| `onDidOpen(listener)` | Subscribe to panel open events. Returns a `Disposable`. |
| `onDidClose(listener)` | Subscribe to panel close events. Returns a `Disposable`. |
| `onDidChangeDisplayMode(listener)` | Subscribe to display mode changes. Returns a `Disposable`. |
| `onDidRegisterChat(listener)` | Subscribe to registration events. |
| `onDidUnregisterChat(listener)` | Subscribe to unregistration events. |
| `onDidResizePanel(listener)` | Subscribe to panel resize events (panel mode only). Not all hosts provide a resizer — do not rely on this firing. Returns a `Disposable`. |
