Event-driven by design

See how your handlers respond to real-time chat events across any platform.

bot.onNewMention(async (thread) => {  await thread.subscribe();  await thread.post("Sure! Here's a quick summary...");});
bot.onReaction(async (thread, reaction) => {  await thread.post(`Thanks for the ${reaction.emoji}!`);});
bot.onSubscribedMessage(async (thread, msg) => {  await thread.post("Checking now...");});

Multi-platform

Deploy to Slack, Teams, Google Chat, Discord, GitHub, and Linear from a single codebase.

Type-safe

Full TypeScript support with type-safe adapters, event handlers, and JSX cards.

AI streaming

First-class support for streaming LLM responses with native platform rendering.

Usage

Install the SDK and pair it with your favorite adapters and state management solutions.

import { Chat } from "chat";import { createSlackAdapter } from "@chat-adapter/slack";import { createRedisState } from "@chat-adapter/state-redis";
export const bot = new Chat({  userName: "mybot",  adapters: {    slack: createSlackAdapter(),  },  state: createRedisState(),});
// Respond when someone @mentions the botbot.onNewMention(async (thread) => {  await thread.subscribe();  await thread.post("Hello! I'm listening to this thread now.");});
// Respond to follow-up messages in subscribed threadsbot.onSubscribedMessage(async (thread, message) => {  await thread.post(`You said: ${ message.text }`);});
