Dry Up Your Initializers with #tap

assets.rb

# Before
Rails.application.config.assets.version = '1.0'
Rails.application.config.assets.paths << Emoji.images_path
Rails.application.config.assets.precompile += %w( search.js )

# After
Rails.application.config.assets.tap do |assets|
  assets.version = '1.0'
  assets.paths << Emoji.images_path
  assets.precompile += %w( search.js )
end

It's worth noting that #tap is very similar to #map, which might cause confusion.

As a guide, it is better to be clearer.
But as a developer you can just use whatever you want :P

Great 👍

As alternative you can use instance_eval here:

Rails.application.config.assets.instance_eval do
  # 'self' here is your assets config
  self.version = '1.0'
  self.paths << Emoji.images_path
end
