Chat SDK

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

Start with published sources

When Chat SDK is installed in a user project, inspect the published files that ship in `node_modules`:

node_modules/chat/docs/                    # bundled docs
node_modules/chat/dist/index.d.ts          # core API types
node_modules/chat/dist/jsx-runtime.d.ts    # JSX runtime types
node_modules/chat/docs/contributing/       # adapter-authoring docs
node_modules/chat/docs/guides/             # framework/platform guides

If one of the paths below does not exist, that package is not installed in the project yet.

Read these before writing code:

• `node_modules/chat/docs/getting-started.mdx` — install and setup
• `node_modules/chat/docs/usage.mdx` — `Chat` config and lifecycle
• `node_modules/chat/docs/handling-events.mdx` — event routing and handlers
• `node_modules/chat/docs/threads-messages-channels.mdx` — thread/channel/message model
• `node_modules/chat/docs/posting-messages.mdx` — post, edit, delet
