GitHub - tionsys/node-telegram-bot-api: Telegram Bot API for NodeJS

![https://telegram.me/node_telegram_bot_api](https://img.shields.io/badge/💬 Telegram-node__telegram__bot__api-blue.svg) ![https://telegram.me/Yago_Perez](https://img.shields.io/badge/💬 Telegram-Yago__Perez-blue.svg)

Node.js module to interact with official Telegram Bot API. A bot token is needed, to obtain one, talk to @botfather and create a new bot.

npm install node-telegram-bot-api

var TelegramBot = require('node-telegram-bot-api');

var token = 'YOUR_TELEGRAM_BOT_TOKEN';
// Setup polling way
var bot = new TelegramBot(token, {polling: true});

// Matches /echo [whatever]
bot.onText(/\/echo (.+)/, function (msg, match) {
  var fromId = msg.from.id;
  var resp = match[1];
  bot.sendMessage(fromId, resp);
});

// Any kind of message
bot.on('message', function (msg) {
  var chatId = msg.chat.id;
  // photo can be: a file path, a stream or a Telegram file_id
  var photo = 'cats.png';
  bot.sendPhoto(chatId, photo, {caption: 'Lovely kittens'});
});

There are some other examples on examples.

Events

Every time TelegramBot receives a message, it emits a message. Depending on which message was received, emits an event from this ones: text, audio, document, photo, sticker, video, voice, contact, location, new_chat_participant, left_chat_participant, new_chat_title, new_chat_photo, delete_chat_photo, group_chat_created. Its much better to listen a specific event rather than a message in order to stay safe from the content. TelegramBot emits inline_query when receives an Inline Query and chosen_inline_result when receives a ChosenInlineResult. Bot must be enabled on inline mode

WebHooks

Telegram only supports HTTPS connections to WebHooks, in order to set a WebHook a private key file and public certificate must be used. Since August 29, 2015 Telegram supports self signed ones, to generate them:

# Our private cert will be key.pem, keep in private this file.
openssl genrsa -out key.pem 2048
# Our public certificate will be crt.pem
openssl req -new -sha256 -key key.pem -out crt.pem

Once they are generated, the crt.pem can be provided to telegramBot.setWebHook(url, crt) as crt.
