Munster

Munster is a Rails engine that provides a webhook endpoint for receiving and processing webhooks from various services. Engine stores received webhook first and later processes webhook in a separete async process.

Install the gem and add to the application's Gemfile by executing:

$ bundle add munster

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install munster

Generate migrations and initializer file.

bin/rails g munster:install

Mount munster engine in your routes.

mount Munster::Engine, at: "/webhooks"

Define a class for your first handler (let's call it ExampleHandler) and inherit it from Munster::BaseHandler. Place it somewhere where Rails autoloading can find it, and add it to your munster.rb config file:

config.active_handlers = {
  "example" => "ExampleHandler"
}

We provide a number of webhook handlers which demonstrate certain features of Munster. You will find them in handler-examples.

This project depends on two dependencies:

• Ruby >= 3.0
• Rails >= 7.0

This gem uses Rails common error reporter to report any possible error to services like Honeybadger, Appsignal, Sentry and etc. Most of those services already support this common interface, if not - it's not that hard to add this support on your own.

It's possible to provide additional context for every error. e.g.

Munster.configure do |config|
  config.error_context = { appsignal: { namespace: "webhooks" } }
end

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 the created tag, and push the .gem file to rubygems.org.
