Devise Async provides an easy way to configure Devise to send its emails asynchronously using ActiveJob.

Add this line to your application's Gemfile:

gem 'devise-async'

And then execute:

$ bundle

Or install it yourself as:

$ gem install devise-async

1. Setup ActiveJob,
2. Add :async to the devise call in your model:

class User < ActiveRecord::Base
  devise :database_authenticatable, :async, :confirmable # etc ...
end

The gem can be enabled/disabled easily via config, for example based on environment.

# config/initializers/devise_async.rb
Devise::Async.enabled = true # | false

To avoid repeating Devise::Async in the initializer file you can use the block syntax similar to what Devise offers.

# config/initializers/devise_async.rb
Devise::Async.setup do |config|
  config.enabled = true
end

Customize Devise.mailer at will and devise-async will honor it.

If you want to use this gem with Rails < 5 and/or devise < 4 check out older releases, please.

RSpec is used for testing. The following should be enough for running the test:

$ bundle exec rspec

3. Commit your changes (git commit -am 'Added some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request
