Usage

Delivery methods

A delivery method handles the process of sending your notifications to various services for you.

Defining a delivery method

You register delivery methods in your NotificationPusher configuration (config/initializers/notification-pusher.rb). Using:

NotificationPusher.configure do |config|
  config.register_delivery_method name, class_name, options
end

More details about defining a specific delivery method (name and available options) are available in the respective documentation of the gem.

Using a delivery method

It is super simple to initialize a delivery:

notification = Notification.create(target: User.first, object: Recipe.first)
notification.deliver(name, custom_options)

Where name is the name of the defined delivery method and custom_options are the options that will override the default options the delivery method has been defined with.

You are also able to do the exact same in just one line of code:

notification = Notification.create(target: User.first, object: Recipe.first, delivery_method: name, delivery_options: custom_options)

Note: In this case, pass custom_options as a Hash.

It is possible to use mutliple delivery methods at a time:

notification.deliver([name_one, name_two], name_one: custom_options, name_two: custom_options)

Writing a custom delivery method

Writing custom delivery methods is fairly simple. Just add a new class to the NotificationPusher::DeliveryMethod namespace:

module NotificationPusher
  module DeliveryMethod
    class CustomPusher < NotificationPusher::DeliveryMethod::Base
      def call
        # `notification` and `options` are accessible here
      end
    end
  end
end

This is how to register and use your delivery method:

NotificationPusher.configure do |config|
  config.register_delivery_method :custom, :CustomPusher, option_one: 'value_one'
end

notification = Notification.create(target: User.first, object: Recipe.first)
notification.deliver(:custom, option_one: 'value_two')
