Telegram Adapter Support

Chat SDK now supports Telegram, extending its single‑codebase approach to Slack, Discord, GitHub, and Teams with the new Telegram adapter.

Key Features

• Mentions, reactions, direct messages, and typing indicators are supported.
• Handles single file uploads and renders basic text cards.
• Buttons and link buttons appear as inline keyboard elements, enabling interactive workflows directly within Telegram chats.

Getting Started

import { Chat } from "chat";
import { createTelegramAdapter } from "@chat-adapter/telegram";

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

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

Limitations

• Telegram does not expose full historical message APIs to bots, so message history relies on adapter‑level caching.
• Callback data is limited to 64 bytes.
• The platform currently does not support modals or ephemeral messages.
