A fuss-free, thin wrapper around Telegram Bot API for Node.js. No frills.

Updated for Bot API 4.1.


Getting started

npm i slimbot
const Slimbot = require('slimbot');
const slimbot = new Slimbot(process.env['TELEGRAM_BOT_TOKEN']);

// Register listeners

slimbot.on('message', message => {
  slimbot.sendMessage(, 'Message received');

// Call API


Now go ahead and type a message to your bot in Telegram. It should reply you with 'Message received' in the chat.

How it works

All methods return a promise. This means you can inspect the returned objects if you want to:

slimbot.sendMessage('123456789', 'Message received')
  .then(message => {

In this case, the sendMessage method returns a Message object as stated in the documentation.

You can also use callbacks instead of promises:

const Slimbot = require('./src/slimbot');
const slimbot = new Slimbot(process.env['TELEGRAM_BOT_TOKEN']);

function callback(err, obj) {
  if (err) {
    // handle error
  // handle returned object

slimbot.on('message', message => {
  slimbot.sendMessage(, 'Message received', callback);

The guiding principle for this library is to be as simple as possible. I put serious thought into adding features to guard against bloat. Nonetheless, I am very open to dialogue and contributions are most welcome.

If you have built a public bot using this library, send me a PM and I'll feature it here.
