The example of a bot that responds with a file containing a user message inside.

import { TelegramBot, UpdateType } from "https://deno.land/x/telegram_bot_api/mod.ts"

const TOKEN = Deno.env.get("TOKEN");
if (!TOKEN) throw new Error("Bot token is not provided");
const bot = new TelegramBot(TOKEN);

bot.on(UpdateType.Message, async ({ message }) => {
  const text = message.text || "I can't hear you";
  await bot.sendDocument({
    chat_id: message.chat.id,
    document: new File([text], "echo.txt"),
  });
});

bot.run({
  polling: true,
});

Let’s run the example above right from the terminal:
