Introducing npm i chat – One codebase, every chat platform
By Steven Van ·
The open-source TypeScript library, in public beta, lets teams write bot logic once for Slack, Teams, Google Chat, Discord, GitHub, and Linear.
Vercel has open sourced Chat SDK, a TypeScript library now in public beta that lets teams write bot logic once and deploy it to Slack, Microsoft Teams, Google Chat, Discord, GitHub, and Linear.
- Event-driven handlers for mentions, messages, reactions, button clicks, and slash commands
- JSX cards and modals that render natively on each platform
- Distributed state via pluggable adapters for Redis, ioredis, and in-memory storage
- Messages can be posted as strings, objects, ASTs, or JSX, and post() functions accept an AI SDK text stream for streaming AI responses in real time
The SDK starts with a core chat package and adds platform support through modular adapters, with guides for building a Slack bot with Next.js and Redis, a Discord support bot with Nuxt, a GitHub bot with Hono, and automated code review bots. Full details are in the Chat SDK documentation.
