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](https://telegram.me/BotFather) and create a new bot.

```sh
npm install node-telegram-bot-api
```

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

// replace the value below with the Telegram token you receive from @BotFather
var token = 'YOUR_TELEGRAM_BOT_TOKEN';

// Create a bot that uses 'polling' to fetch new updates
var bot = new TelegramBot(token, { polling: true });

// Matches "/echo [whatever]"
bot.onText(/\/echo (.+)/, function (msg, match) {
  // 'msg' is the received Message from Telegram
  // 'match' is the result of executing the regexp above on the text content
  // of the message

  var chatId = msg.chat.id;
  var resp = match[1]; // the captured "whatever"

  // send back the matched "whatever" to the chat
  bot.sendMessage(chatId, resp);
});

// Listen for any kind of message. There are different kinds of
// messages.
bot.on('message', function (msg) {
  var chatId = msg.chat.id;

  // send a message to the chat acknowledging receipt of their message
  bot.sendMessage(chatId, "Received your message");
});
```

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.
TelegramBot emits `callback_query` when receives a [Callback Query](https://core.telegram.org/bots/api#callbackquery).
TelegramBot emits `inline_query` when receives an [Inline Query](https://core.telegram.org/bots/api#inlinequery) and `chosen_inline_result` when receives a [ChosenInlineResult](https://core.telegram.org/bots/api#choseninlineresult). Bot must be enabled on [inline mode](https://core.telegram.org/bots/api#inline-mode).
TelegramBot emits `channel_post` on a new incoming channel post of any kind.
TelegramBot emits `edited_message` when a message is edited, and also `edited_message_text` or `edited_message_caption` depending on which type of message was edited.
TelegramBot emits `edited_channel_post` when a channel post is edited, and also `edited_channel_post_text` or `edited_channel_post_caption` depending on which type of channel post was edited.

### 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:
```bash
# 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`.
