Telegram::Bot::ResponseBuilder

This gem extends telegram-bot-ruby by enabling responding to Telegram webhook requests directly in the response body. It introduces a Telegram::Bot::Api subclass which builds response hash from parameters and the method name instead of performing an HTTP request.

Add this line to your application's Gemfile:

gem 'telegram-bot-response_builder'

And then execute:

$ bundle

Or install it yourself as:

$ gem install telegram-bot-response_builder

Create new instance of Telegram::Bot::ResponseBuilder and invoke any API method on it:

# ...
response_builder = Telegram::Bot::ResponseBuilder.new
response_builder.deleteMessage(chat_id: chat_id, message_id: message_id)
# {:method=>"deleteMessage", :chat_id=>chat_id, :message_id=>message_id}

Example — webhook-based "echo" bot, built on top of Sinatra:

require 'sinatra'
require 'sinatra/json'

class TelegramWebhookBot < Sinatra::Base
  use Rack::PostBodyContentTypeParser
  register Sinatra::JSON

  post '/webhooks/tg' do
    message = Telegram::Bot::Types::Update.new(params).message
    response_builder = Telegram::Bot::ResponseBuilder.new
    json response_builder.send_message(chat_id: message.chat.id, text: message.text)
    # response: {"chat_id":9001,"text":"Hello, World!","method":"sendMessage"}
  end
end

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
