chat-sdk

Create a Chat instance with createSlackAdapter from @chat-adapter/slack, register handlers like onNewMention, and route HTTP requests to bot.webhooks.slack in your framework. The same bot logic can later add Teams or Discord adapters without changes.

Pass any AsyncIterable of strings to thread.post or thread.stream. With the AI SDK, prefer result.fullStream over result.textStream so step boundaries are preserved, and configure streamingUpdateIntervalMs for post-and-edit fallback cadence.

Official adapters cover Slack, Microsoft Teams, Google Chat, Discord, GitHub, Linear, Telegram, and WhatsApp Business Cloud. Community adapters add Matrix, iMessage, Webex, and others, with Instagram, Signal, X, and Messenger listed as coming soon.

Official state adapters include Redis, ioredis, PostgreSQL, and in-memory implementations. They handle persistence for subscriptions, locks, deduplication, and thread state, with dedupeTtlMs configurable on the Chat instance.

No. Structured StreamChunk support is Slack-only; other adapters ignore non-text chunks and fall back to plain text streaming. Text streaming via post-and-edit works across platforms, controlled by streamingUpdateIntervalMs.

Set jsxImportSource to chat in tsconfig.json, then compose Card, Button, Actions, Select, and Modal components in JSX. Handle interactions with onAction, onModalSubmit, and onModalClose handlers filtered by action or callback IDs.
