WebhookHandler Build Status

Combines Rack and Sidekiq into a neat package that makes creating simple apps that respond to webhooks a pleasure.

Installation

Add this line to your application's Gemfile:

gem 'webhook_handler'

And then execute:

$ bundle

Or install it yourself as:

$ gem install webhook_handler

Usage

Define a class and include the WebhookHandler module. This class then acts as a Sidekiq worker and a Rack app.

app.rb

require 'webhook_handler'

class MyApp
  include WebhookHandler

  def perform
    puts "Working hard!"
    sleep 5
  end
end

config.ru

require_relative './app'
run MyApp

If you want to pass some arguments from the request into the background job you can define a handle_webhook method.

class MyApp
  include WebhookHandler

  def handle_webhook
    request.body.rewind
    payload = JSON.parse(request.body.read)
    self.class.perform_async(payload['message'])
  end

  def perform(message)
    puts "Got a message: #{message}"
    # Do some long running task...
    sleep 2
  end
end

CLI

You can also generate a new app with the command line tool:

$ webhook_handler new acme_widget_receiver

This will generate a new app in the acme_widget_receiver directory with the class AcmeWidgetReceiver in the app.rb file.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test 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.
