🎨 Deep-dive into Rails ViewComponent Patterns​

Extract complex UI logic into reusable, testable ViewComponents to keep your views thin and maintainable. Implement composition by nesting components and passing child components via slots instead of partials.

# app/components/comment_list_component.rb
class CommentListComponent < ViewComponent::Base
  renders_many :comments, CommentComponent
end

# app/components/comment_component.rb
class CommentComponent < ViewComponent::Base
  def initialize(author:, content:)
    @author = author
    @content = content
  end
end

Use slots to define optional regions:

# app/components/card_component.rb
class CardComponent < ViewComponent::Base
  renders_one :header
  renders_one :footer
end

This pattern scales for highly dynamic UI compositions without polluting view templates.
