Overview

Chat SDK now supports Messenger as a chat adapter.

Build agents that support messages, reactions, multimedia downloads, postback buttons, and direct conversations, with display names fetched automatically from user profiles.

Example

import { Chat } from "chat";
import { createMessengerAdapter } from "@chat-adapter/messenger";

const bot = new Chat({
  userName: "mybot",
  adapters: {
    messenger: createMessengerAdapter(),
  },
});

bot.onDirectMessage(async (thread, message) => {
  await thread.post(`You said: ${message.text}`);
});

Echo each new mention back to the sender.
