Installation

Download and install via npm package manager (stable):

npm install telebot

Or clone fresh code directly from git:

git clone https://github.com/kosmodrey/telebot.git
cd telebot
npm install

Usage

Import telebot module and create a new bot object:

const TeleBot = require('telebot');

const bot = new TeleBot({
  token: '-PASTEYOURTELEGRAMBOTAPITOKENHERE-', // Required. Telegram Bot API token.
  polling: { // Optional. Use polling.
    interval: 1000, // Optional. How often check updates (in ms).
    timeout: 0, // Optional. Update polling timeout (0 - short polling).
    limit: 100, // Optional. Limits the number of updates to be retrieved.
    retryTimeout: 5000 // Optional. Reconnecting timeout (in ms).
  },
  webhook: { // Optional. Use webhook instead of polling.
    key: '__YOUR_KEY__.pem', // Optional. Private key for server.
    cert: '__YOUR_CERT__.pem', // Optional. Public key.
    url: 'https://....', // HTTPS url to send updates to.
    host: '0.0.0.0', // Webhook server host.
    port: 443 // Server port.
  },
  modules: {
    // Optional. Module configuration.
    //
    // Example:
    //
    // myModuleName: {
    //   data: 'my module data'
    // }
    }
  }
});

Or just:

const TeleBot = require('telebot');
const bot = new TeleBot('-PASTEYOURTELEGRAMBOTAPITOKENHERE-');

Replace token value to your Telegram Bot API token key.

To start getting updates, use bot.connect().

bot.on('text', msg => {
  let fromId = msg.from.id;
  let firstName = msg.from.first_name;
  let reply = msg.message_id;
  return bot.sendMessage(fromId, `Welcome, ${ firstName }!`, { reply });
});

bot.connect();

This code will send a "welcome" to every users text type message as a reply.

Events

Use bot.on(<event>, <function>) to handle all possible TeleBot events.

To catch a command with arguments, just add a slash:

bot.on('/hello', msg => {
  let [cmdName, firstName, lastName] = msg.text.split(' ');
  return bot.sendMessage(msg.from.id, `Hello, ${ firstName } ${ lastName }!`);
});

Also, you can catch multiple events:

bot.on(['/start', '/help', 'sticker'], msg => {
  return bot.sendMessage(msg.from.id, 'Bam!');
});

• /* – any user command
• /<cmd> – on specific command

• tick – on bot tick
• error – an error occurred
• inlineQuery - inline query data
• inlineChoice - inline query chosen result
• callbackQuery - button callback data

Action events:

keyboard, button, inlineKeyboard, inlineQueryKeyboard, inlineButton, answerList, getMe, sendMessage, forwardMessage, sendPhoto, sendAudio, sendDocument, sendSticker, sendVideo, sendVoice, sendLocation, sendVenue, sendContact, sendChatAction, getUserProfilePhotos, getFile, kickChatMember, unbanChatMember, answerInlineQuery, answerCallbackQuery, editMessageText, editMessageCaption, editMessageReplyMarkup, setWebhook

Modifiers

You can add modifier to process data before passing it to event.

bot.mod('text', data => {
  let msg = data.msg;
  msg.text = `📢 ${ msg.text }`;
  return data;
});

This code adds emoji to every text message.

• message - process any type of message
• <type> - specific type of message (text, voice, document, photo, sticker, video, contact, location or venue)
