Build Status

The aim of this gem is to provide a useful wrapper of Telegram's Bot API that makes use of Webhooks functionality.

Installation

Add this line to your application's Gemfile:

gem 'fantastic_robot'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fantastic_robot

Configuration

Gem configuration can be initialized by running a custom generator:

$ rails g fantastic_robot:install

Then, you can change the configuration by editing the file located at config/initializers/fantastic_robot.rb

At least, you should include:

  • Your bot's token
  • Your web hook callback URL (in which you'll receive the updates sent to your bot).

Important: your webhook we'll be registered only if the delivery_method is set to :delivery_method.

Usage

This gem provides models to access easily to API updates, and to create responses and requests to send messages and attachments to Telegram.

Models

Used to parse received data from Telegram.

Available models are:

  • FantasticRobot::Model::Chat
  • FantasticRobot::Model::Message
  • FantasticRobot::Model::Update
  • FantasticRobot::Model::User
  • FantasticRobot::Model::Attachment::Audio
  • FantasticRobot::Model::Attachment::Contact
  • FantasticRobot::Model::Attachment::Document
  • FantasticRobot::Model::Attachment::Location
  • FantasticRobot::Model::Attachment::PhotoSize
  • FantasticRobot::Model::Attachment::Sticker
  • FantasticRobot::Model::Attachment::Video
  • FantasticRobot::Model::Attachment::Voice

If you want to know the variables available in each one, you can check the official docs.

And they can be instantiated like any other model. You will commonly receive an Update object:

received_hash = JSON.parse(request.body.read)
received_update = FantasticRobot::Model::Update.new(received_hash)

Associated models (like the Message included inside the Update) will be automatically converted when instantiating the Update object.

Requests

Request are objects that can receive (and validate) the parameters that can be sent in a request to the API.

The available requests are:

  • FantasticRobot::Request::ForwardMessage
  • FantasticRobot::Request::GetMe
  • FantasticRobot::Request::SendAudio
  • FantasticRobot::Request::SendChatAction
  • FantasticRobot::Request::SendDocument
  • FantasticRobot::Request::SendLocation
  • FantasticRobot::Request::SendMessage
  • FantasticRobot::Request::SendPhoto
  • FantasticRobot::Request::SendSticker
  • FantasticRobot::Request::SendVideo
  • FantasticRobot::Request::SendVoice
  • FantasticRobot::Request::SetWebhook

If you want to know the variables available in each one, you can check the official docs.

Sending a request

There are two ways of sending a request:

  • All of them can be send asynchronously to the API using the #send_request method available in all request classes:
req = FantasticRobot::Request::GetMe.new()
response = req.send_request

Note: if the API returns an error, a Faraday::Error exception will be raised

  • Synchronously as the response to the updates reception in the webhook callback URL. For example:
def receive
  received = FantasticRobot::Model::Update.new(JSON.parse(request.body.read))

  response = FantasticRobot::Request::SendMessage.new({
    chat_id: received.message.chat.id,
    text: "Okay! I've got it!",
    reply_to_message_id: received.message.message_id
  })

  render json: response
end

Unit testing

Several tests have been implemented to verify that model an requests behave as expected.

So please, if you want to contribute to this gem, check that tests are maintained and all of them pass.

To-Do

There are several thing to do on this project:

  • Receiving updates by polling.
  • Getting user profile photos from the API.
  • Create models of custom keyboard responses (actually they can be hardcoded as a Hash object, check the documentation).
  • Inline queries.

If you want to check out the gem's source code and want to contribute, you are welcome!
