I'm listening to this thread.\");\n});\n\nbot.onSubscribedMessage(async (thread, message) => {\n  await thread.post(`You said: ${message.text}`);\n});\n```\n\n## Core concepts\n\n- **Chat** — main entry point; coordinates adapters, routing, locks, and state\n- **Adapters** — platform-specific integrations for Slack, Teams, Google Chat, Discord, Telegram, GitHub, Linear, and WhatsApp\n- **State adapters** — persistence for subscriptions, locks, dedupe, and thread state\n- **Thread** — conversation context with `post()`, `stream()`, `subscribe()`, `setState()`, `startTyping()`\n- **Message** — normalized content with `text`, `formatted`, attachments, author info, and platform `raw`\n- **Channel** — container for threads and top-level posts\n\n## Event handlers\n\n| Handler | Trigger |\n|---------|---------|\n| `onNewMention` | Bot @-mentioned in an unsubscribed thread |\n| `onDirectMessage` | New DM in an unsubscribed DM thread |\n| `onSubscribedMessage` | Any message in a subscribed thread |\n| `onNewMessage(regex)` | Regex match in an unsubscribed thread |\n| `onReaction(emojis?)` | Emoji added or removed |\n| `onAction(actionIds?)` | Button clicks and select/radio interactions |\n| `onModalSubmit(callbackId?)` | Modal form submitted |\n| `onModalClose(callbackId?)` | Modal dismissed/cancelled |\n| `onSlashCommand(commands?)` | Slash command invocation |\n| `onAssistantThreadStarted` | Slack assistant thread opened |\n| `onAssistantContextChanged` | Slack assistant context changed |\n| `onAppHomeOpened` | Slack App Home opened |\n| `onMemberJoinedChannel` | Slack member joined channel event |\n\nRead `node_modules/chat/docs/handling-events.mdx`, `node_modules/chat/docs/actions.mdx`, `node_modules/chat/docs/modals.mdx`, and `node_modules/chat/docs/slash-commands.mdx` before wiring handlers. `onDirectMessage` behavior is documented in `node_modules/chat/docs/direct-messages.mdx`.\n\n## Streaming\n\nPass any `AsyncIterable<string>` to `thread.post()` or `thread.stream()`. For AI SDK, prefer `result.fullStream` over `result.textStream` when available so step boundaries are preserved.\n\n```typescript\nimport { ToolLoopAgent } from \"ai\";\n\nconst agent = new ToolLoopAgent({ model: \"anthropic/claude-4.5-sonnet\" });\n\nbot.onNewMention(async (thread, message) => {\n  const result = await agent.stream({ prompt: message.text });\n  await thread.post(result.fullStream);\n});\n```\n\nKey details:\n- `streamingUpdateIntervalMs` controls post+edit fallback cadence\n- `fallbackStreamingPlaceholderText` defaults to `\"...\"`; set `null` to disable\n- Structured `StreamChunk` support is Slack-only; other adapters ignore non-text chunks\n\n## Cards and modals (JSX)\n\nSet `jsxImportSource: \"chat\"` in `tsconfig.json`.\n\nCard components:\n- `Card`, `CardText`, `Section`, `Fields`, `Field`, `Button`, `CardLink`, `LinkButton`, `Actions`, `Select`, `SelectOption`, `RadioSelect`, `Table`, `Image`, `Divider`\n\nModal components:\n- `Modal`, `TextInput`, `Select`, `SelectOption`, `RadioSelect`\n\n```tsx\nawait thread.post(\n  <Card title=\"Order #1234\">\n    <CardText>Your order has been received.</CardText>\n    <Actions>\n      <Button id=\"approve\" style=\"primary\">Approve</Button>\n      <Button id=\"reject\" style=\"danger\">Reject</Button>\n    </Actions>\n  </Card>\n);\n```\n\n## Adapter inventory\n\n### Official platform adapters\n\n| Platform | Package | Factory |\n|---------|---------|---------|\n| Slack | `@chat-adapter/slack` | `createSlackAdapter` |\n| Microsoft Teams | `@chat-adapter/teams` | `createTeamsAdapter` |\n| Google Chat | `@chat-adapter/gchat` | `createGoogleChatAdapter` |\n| Discord | `@chat-adapter/discord` | `createDiscordAdapter` |\n| GitHub | `@chat-adapter/github` | `createGitHubAdapter` |\n| Linear | `@chat-adapter/linear` | `createLinearAdapter` |\n| Telegram | `@chat-adapter/telegram` | `createTelegramAdapter` |\n| WhatsApp Business Cloud | `@chat-adapter/whatsapp` | `createWhatsAppAdapter` |\n\n### Official state adapters\n\n| State backend | Package | Factory |\n|--------------|---------|---------|\n| Redis | `@chat-adapter/state-redis` | `createRedisState` |\n| ioredis | `@chat-adapter/state-ioredis` | `createIoRedisState` |\n| PostgreSQL | `@chat-adapter/state-pg` | `createPostgresState` |\n| Memory | `@chat-adapter/state-memory` | `createMemoryState` |\n\n### Community adapters\n\n- `chat-state-cloudflare-do`\n- `@beeper/chat-adapter-matrix`\n- `chat-adapter-imessage`\n- `@bitbasti/chat-adapter-webex`\n- `@resend/chat-sdk-adapter`\n- `chat-adapter-baileys`\n\n### Coming-soon platform entries\n\n- Instagram\n- Signal\n- X\n- Messenger\n\n## Building a custom adapter\n\nRead these published docs first:\n- `node_modules/chat/docs/contributing/building.mdx`\n- `node_modules/chat/docs/contributing/testing.mdx`\n- `node_modules/chat/docs/contributing/publishing.mdx`\n\nAlso inspect:\n- `node_modules/chat/dist/index.d.ts` — `Adapter` and related interfaces\n- `node_modules/@chat-adapter/shared/dist/index.d.ts` — shared errors and utilities\n- Installed official adapter `dist/index.d.ts` files — reference implementations for config and APIs\n\nA custom adapter needs request verification, webhook parsing, message/thread/channel operations, ID encoding/decoding, and a format converter. Use `BaseFormatConverter` from `chat` and shared utilities from `@chat-adapter/shared`.\n\n## Webhook setup\n\nEach registered adapter exposes `bot.webhooks.<name>`. Wire those directly to your HTTP framework routes. See `node_modules/chat/docs/guides/slack-nextjs.mdx` and `node_modules/chat/docs/guides/discord-nuxt.mdx` for framework-specific route patterns.\n"
