ViewComponent::FragmentCaching

With fragment caching in Rails, updates to a partial's source code will automatically bust appropriate caches in which the partial is detectable as a dependency.

This gem augments ActionView's fragment caching strategy to detect and parse view components. In addition to digesting a component's view file (if present), it will also digest the component's ruby file and those of any superclasses descended from ViewComponent::Base.

Add this line to your application's Gemfile:

gem "view_component-fragment_caching"

And then execute:

$ bundle

Or install it yourself as:

$ gem install view_component-fragment_caching

By default, view components will be detected in ViewComponent::Base.view_component_path (app/components typically). This can be configured in an initializer:

ViewComponent::FragmentCaching.configure do |c|
  c.view_component_paths = %w(
    app/components
    app/additional_components
  )
end

It is important that naming conventions are followed. The tracker will ignore components whose class names do not end with "Component".

<%= render Users::AuthorComponent.new(...) %>
<%= render Users::AuthorComponent.with_collection(...) %>

<%# View Component Dependency: Users::AuthorComponent %>
<%= render @author %>  

Please follow conventions and write tests.

$ bundle exec rspec
$ bundle exec rubocop
