Slimbot

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

Updated for Telegram Bot API 4.6. Works with Node 13.11.0. Tested on 10.16.0 and 12.10.0 as well.

Note: Slimbot patch versions (e.g. x.y.Z) do not track or reflect Telegram Bot API changes.

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.chat.id, 'Message received');
});
 
// Call API
 
slimbot.startPolling();

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 => {
    console.log(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
    console.log(obj);
  }
  // handle returned object
  console.log(obj);
};
 
slimbot.on('message', message => {
  slimbot.sendMessage(message.chat.id, 'Message received', callback);
});
 
slimbot.startPolling(callback);

Contributing

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.
