Eztek MediatR

Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/eztek/mediat_r. To experiment with that code, run bin/console for an interactive prompt.

Installation

Add this line to your application's Gemfile:

gem 'eztek-mediat_r'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install eztek-mediat_r

Usage

Initialize mediatR

Add new file config/initializers/mediat_r.rb to initializer mediatR

require 'ez/mediat_r'

mediator = EZ::MediatR.new
Rails.configuration.to_prepare do
    Rails.configuration.bus = Bus.new
    Rails.configuration.bus.tap do |bus|
        # Register command - handler
        bus.register(Auth::Commands::LoginCommand, Auth::Commands::Handlers::LoginCommandHandler.new)
    end
end

Declare mediatR in controller

def initialize
    @mediator = Rails.configuration.bus
end

or dependency with dry-container, dry-auto_inject:

Register mediaR in container

Use file dependency.rb to register mediatR

require 'ez/mediat_r'

dependency_container = Dry::Container.new
dependency_container.register('mediator', -> { EZ::MediatR.new })
AutoInject = Dry::AutoInject(dependency_container)

Define mediatR in controller

include AutoInject['mediator']

Run mediator

command = Auth::Commands::LoginCommand.new(username, password)
mediator.execute(command) 

Generator structure with rails

    $ rails generate command feature command_name

Example:

    $ rails generate command auth login

This will create: app/cqrs/auth/commands/login_command.rb app/cqrs/auth/commands/validators/login_command_validator.rb app/cqrs/auth/commands/handlers/login_command_handler.rb

Development

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