Getting started with Phlex on Rails

While Phlex can be used in any Ruby project, it’s especially great with Rails. But before we get into the details, it’s important to understand that Phlex is very different from ActionView and ViewComponent.


To use Phlex with Rails, you’ll need to install the phlex-rails gem. Add the following to your Gemfile and run bundle install.

gem "phlex-rails"

Note, you do not need to install phlex separately because phlex is a dependency of phlex-rails.

Once the gem is installed, run the install generator.

bin/rails generate phlex:install

This script will:

  1. update config/application.rb to include app/views, app/views/components, and app/views/layouts in your auto-load paths;
  2. generate views/application_view.rb
  3. generate views/layouts/application_layout.rb
  4. generate views/components/application_component.rb

ApplicationComponent is your base component which all your other components inherit from. By default, ApplicationView inherits from ApplicationComponent.
