Slimbot

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

Updated for Telegram Bot API 5.1. Works with Node 15.12.0. Runs on latest Node version 15.12.0. 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.

Resources

Getting started

npm i slimbot

const Slimbot = require('slimbot');
const slimbot = new Slimbot('123456789:AA...');

// 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. Check out all other events you can listen to in the wiki.

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(err);
  }
  // handle returned object
  console.log(obj);
};

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

slimbot.startPolling(callback);

Heartfelt thanks to the following folks for making Slimbot better: @lgg @ago @rpaskin @matteocontrini @jakimenko @nahanil

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.
