A Ruby gem. It connects to Slack Real Time Messaging API to receive events. Runs on EventMachine.

Requirements

• eventmachine 1.0 <=
• em-http-request 1.1 <=
• faye-websocket 0.8 <=

Getting Started

Install

$ gem install slack-rtm-receiver

Use

require 'slack-rtm-receiver'

Create an object to respond to received events. You can subclass EventHandler.

class MyHandler < SlackRTMReceiver::EventHandler
  def process_event(event, session)
    if event[:text] == 'hi'
      res_event = {
        type: 'message',
        channel: event[:channel],
        text: 'Hi!'
      }
      session.send_event(res_event)
    end
  end
end
SlackRTMReceiver.add_event_handler(MyHandler.new)

Or, you can pass a block. The following works the same as above.

SlackRTMReceiver::EventHandler.add_type('message') do |event, session|
  if event[:text] == 'hi'
    res_event = {
      type: 'message',
      channel: event[:channel],
      text: 'Hi!'
    }
    session.send_event(res_event)
  end
end

Start the reactor to connect to Slack.

opts = {token: 'xoxb-1234abcd5678efgh'}
SlackRTMReceiver::Reactor.run(opts)
