๐Ÿ”จ Installation

Download and install via npm package manager (stable):

npm install telebot --save

Or clone fresh code directly from git:

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

๐Ÿ•น Usage

Import telebot module and create a new bot object:

const TeleBot = require('telebot');

const bot = new TeleBot({
    token: 'TELEGRAM_BOT_TOKEN', // 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).
        proxy: 'http://username:password@yourproxy.com:8080' // Optional. An HTTP proxy to be used.
    },
    webhook: { // Optional. Use webhook instead of polling.
        key: 'key.pem', // Optional. Private key for server.
        cert: '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.
        maxConnections: 40 // Optional. Maximum allowed number of simultaneous HTTPS connections to the webhook for update delivery
    },
    allowedUpdates: [], // Optional. List the types of updates you want your bot to receive. Specify an empty list to receive all updates.
    usePlugins: ['askUser'], // Optional. Use user plugins from pluginFolder.
    pluginFolder: '../plugins/', // Optional. Plugin folder location.
    pluginConfig: { // Optional. Plugin configuration.
        // myPluginName: {
        //   data: 'my custom value'
        // }
    }
});

Or just:

const TeleBot = require('telebot');
const bot = new TeleBot('TELEGRAM_BOT_TOKEN');

Don't forget to insert your Telegram Bot API token key.

To start polling updates, use bot.start().

bot.on('text', (msg) => msg.reply.text(msg.text));

bot.start();

We just created echo bot!

๐ŸŒฑ Quick examples

Send text on /start or /hello command:

bot.on(['/start', '/hello'], (msg) => msg.reply.text('Welcome!'));

When sticker received, reply back:

bot.on('sticker', (msg) => {
    return msg.reply.sticker('http://i.imgur.com/VRYdhuD.png', { asReply: true });
});

Sends photo on "show kitty" or "kitty" text message (using RegExp):

bot.on(/(show\s)?kitty*/, (msg) => {
    return msg.reply.photo('http://thecatapi.com/api/images/get');
});

Command with arguments /say <your message>:

bot.on(/^\/say (.+)$/, (msg, props) => {
    const text = props.match[1];
    return bot.sendMessage(msg.from.id, text, { replyToMessage: msg.message_id });
});

When message was edited:

bot.on('edit', (msg) => {
    return msg.reply.text('I saw it! You edited message!', { asReply: true });
});

Note: msg.reply is a bot method shortcut, part of shortReply build-in plugin.

See more examples!

โฐ Events

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

For example, to catch a command, just add a slash:

bot.on('/hello', (msg) => {
  return bot.sendMessage(msg.from.id, `Hello, ${ msg.from.first_name }!`);
});

Also, you can catch multiple events:

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

TeleBot events:

  • /* โ€“ any user command
  • /<cmd> โ€“ on specific command

  • tick โ€“ on bot tick
  • error โ€“ an error occurred
  • inlineQuery - inline query data

๐Ÿšœ Modifiers

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

bot.mod('text', (data) => {
  let msg = data.message;
  msg.text = `๐Ÿ“ข ${ msg.text }`;
  return data;
});

This code adds emoji to every text message.

TeleBot modifiers:

  • property - mod form properties
  • updateList - list of updates in one tick
  • update - every update
  • message - process any type of message
  • <type> - specific type of message

๐Ÿ”Œ Plugins

Use usePlugins config option to load plugins from pluginFolder directory:

const bot = new TeleBot({
    token: 'TELEGRAM_BOT_TOKEN',
    usePlugins: ['askUser', 'commandButtons'],
    pluginFolder: '../plugins/',
    pluginConfig: {
        // Plugin configs
    }
});

Or use plug(require(<plugin_path>)) to plug an external plugin.

Check out build-in plugin folder!

Plugin structure

module.exports = {
    id: 'myPlugin', // Unique plugin name
    defaultConfig: {
        // Default plugin config
        key: 'value'
    },
    plugin(bot, pluginConfig) {
        // Plugin code
    }
};
