Node.js module to interact with the official Telegram Bot API.

📦 Install

npm i node-telegram-bot-api

🚀 Usage

import TelegramBot from 'node-telegram-bot-api';
// For CommonJS use:
// const { TelegramBot } = require('node-telegram-bot-api');

// replace the value below with the Telegram token you receive from @BotFather
const token = 'YOUR_TELEGRAM_BOT_TOKEN';

// Create a bot that uses 'polling' to fetch new updates
const bot = new TelegramBot(token, { polling: true });

// Matches "/echo [whatever]" - the leading ^ anchors the command to the start of
// the message, so it won't match "/echo" embedded in a URL or mid-sentence.
bot.onText(/^\/echo (.+)/, (msg, match) => {
  // 'msg' is the received Message from Telegram
  // 'match' is the result of executing the regexp above on the text content
  // of the message

  const chatId = msg.chat.id;
  const resp = match?.[1] ?? ''; // the captured "whatever"

  // send back the matched "whatever" to the chat
  bot.sendMessage(chatId, resp);
});

// Listen for any kind of message. There are different kinds of messages.
bot.on('message', (msg) => {
  const chatId = msg.chat.id;

  // send a message to the chat acknowledging receipt of their message
  bot.sendMessage(chatId, 'Received your message');
});

🌐 Proxy / custom transport

Requests use the built-in fetch. To route a single bot instance through a proxy (without affecting the rest of the process), pass an undici dispatcher via request.fetchOptions:

import TelegramBot from 'node-telegram-bot-api';
import { ProxyAgent } from 'undici';

const bot = new TelegramBot(token, {
  polling: true,
  request: { fetchOptions: { dispatcher: new ProxyAgent('http://127.0.0.1:8080') } },
});

For full control you can supply your own fetch implementation instead via request.fetch (useful for custom proxying, instrumentation, or tests). Both are scoped to that bot instance, so different bots can use different proxies.
