# Chat SDK

Unified TypeScript SDK for building chat bots across Slack, Teams, Google Chat, Discord, GitHub, and Linear. Write bot logic once, deploy everywhere.

## Critical: Read the bundled docs

The `chat` package ships with full documentation in `node_modules/chat/docs/` and TypeScript source types. **Always read these before writing code:**

```
node_modules/chat/docs/           # Full documentation (MDX files)
node_modules/chat/dist/           # Built types (.d.ts files)
```

Key docs to read based on task:
- `docs/getting-started.mdx` — setup guides
- `docs/usage.mdx` — event handlers, threads, messages, channels
- `docs/streaming.mdx` — AI streaming with AI SDK
- `docs/cards.mdx` — JSX interactive cards
- `docs/actions.mdx` — button/dropdown handlers
- `docs/modals.mdx` — form dialogs (Slack only)
- `docs/adapters/*.mdx` — platform-specific adapter setup
- `docs/state/*.mdx` — state adapter config (Redis, ioredis, memory)

Also read the TypeScript types from `node_modules/chat/dist/` to understand the full API surface.

## Quick start

```typescript
import { Chat } from "chat";
import { createSlackAdapter } from "@chat-adapter/slack";
import { createRedisState } from "@chat-adapter/state-redis";

const bot = new Chat({
  userName: "mybot",
  adapters: {
    slack: createSlackAdapter({
      botToken: process.env.SLACK_BOT_TOKEN!,
      signingSecret: process.env.SLACK_SIGNING_SECRET!,
    }),
  },
  state: createRedisState({ url: process.env.REDIS_URL! }),
});

bot.onNewMention(async (thread) => {
  await thread.subscribe();
  await thread.post("Hello! I'm listening to this thread.");
});

bot.onSubscribedMessage(async (thread, message) => {
  await thread.post(`You said: ${message.text}`);
});
```

## Core concepts

- **Chat** — main entry point, coordinates adapters and routes events
- **Adapters** — platform-specific (Slack, Teams, GChat, Discord, GitHub, Linear)
- **State** — pluggable persistence (Redis for prod, memory for dev)
- **Thread** — conversation thread with `post()`, `subscribe()`, `startTyping()`
- **Message** — normalized format with `text`, `formatted` (mdast AST), `raw`
- **Channel** — container for threads, supports listing and posting

## Event handlers

| Handler | Trigger |
|---------|---------|
| `onNewMention` | Bot @-mentioned in unsubscribed thread |
| `onSubscribedMessage` | Any message in subscribed thread |
| `onNewMessage(regex)` | Messages matching pattern in unsubscribed threads |
| `onSlashCommand("/cmd")` | Slash command invocations |
| `onReaction(emojis)` | Emoji reactions added/removed |
| `onAction(actionId)` | Button clicks and dropdown selections |
| `onAssistantThreadStarted` | Slack Assistants API thread opened |
| `onAppHomeOpened` | Slack App Home tab opened |

## Streaming

Pass any `AsyncIterable<string>` to `thread.post()`. Works with AI SDK's `textStream`:

```typescript
import { ToolLoopAgent } from "ai";
const agent = new ToolLoopAgent({ model: "anthropic/claude-4.5-sonnet" });

bot.onNewMention(async (thread, message) => {
  const result = await agent.stream({ prompt: message.text });
  await thread.post(result.textStream);
});
```

## Cards (JSX)

Set `jsxImportSource: "chat"` in tsconfig. Components: `Card`, `CardText`, `Button`, `Actions`, `Fields`, `Field`, `Select`, `SelectOption`, `Image`, `Divider`, `LinkButton`, `Section`, `RadioSelect`.

```tsx
await thread.post(
  <Card title="Order #1234">
    <CardText>Your order has been received!</CardText>
    <Actions>
      <Button id="approve" style="primary">Approve</Button>
      <Button id="reject" style="danger">Reject</Button>
    </Actions>
  </Card>
);
```

## Packages

| Package | Purpose |
|---------|---------|
| `chat` | Core SDK |
| `@chat-adapter/slack` | Slack |
| `@chat-adapter/teams` | Microsoft Teams |
| `@chat-adapter/gchat` | Google Chat |
| `@chat-adapter/discord` | Discord |
| `@chat-adapter/github` | GitHub Issues |
| `@chat-adapter/linear` | Linear Issues |
| `@chat-adapter/state-redis` | Redis state (production) |
| `@chat-adapter/state-ioredis` | ioredis state (alternative) |
| `@chat-adapter/state-memory` | In-memory state (development) |

## Changesets (Release Flow)

This monorepo uses [Changesets](https://github.com/changesets/changesets) for versioning and changelogs. Every PR that changes a package's behavior must include a changeset.

```bash
pnpm changeset
# → select affected package(s) (e.g. @chat-adapter/slack, chat)
# → choose bump type: patch (fixes), minor (features), major (breaking)
# → write a short summary for the CHANGELOG
```

This creates a file in `.changeset/` — commit it with the PR. When merged to `main`, the Changesets GitHub Action opens a "Version Packages" PR to bump versions and update CHANGELOGs. Merging that PR publishes to npm.

## Webhook setup

Each adapter exposes a webhook handler via `bot.webhooks.{platform}`. Wire these to your HTTP framework's routes (e.g. Next.js API routes, Hono, Express).
