Node.js module to interact with official [Telegram Bot API](https://core.telegram.org/bots/api). A bot token is needed, to obtain one, talk to [@botfather](telegram.me/BotFather) and create a new bot.
```sh
npm install node-telegram-bot-api
```
```js
var TelegramBot = require('node-telegram-bot-api');
var token = 'YOUR_TELEGRAM_BOT_TOKEN';
// Setup polling way
var bot = new TelegramBot(token, {polling: true});
bot.on('text', 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](https://github.com/yagop/node-telegram-bot-api/tree/master/examples).
### Events
Every time TelegramBot receives a message, it emits a `message`. Depending on which [message](https://core.telegram.org/bots/api#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.
