Ruby on Rails Phlex step by step setup and configuration

Integrating Phlex into a Ruby on Rails project is a straightforward process. The first step is to add the Phlex gem to your Gemfile and run the bundle install command to install the gem and its dependencies. Here's an example of how to add the Phlex gem to your Gemfile:

gem 'phlex'

Once you have added the Phlex gem to your Gemfile, you can create a new Phlex template by creating a new file with the .phlx extension in the app/views directory. Here's an example of a simple Phlex template:

<%# app/views/welcome/index.phlx %>
<!DOCTYPE html>
<html>
  <head>
    <title>Welcome to my app</title>
  </head>
  <body>
    <h1>Hello, <%= @name %>!</h1>
  </body>
</html>

In this example, we have created a new Phlex template called index.phlx in the app/views/welcome directory. The template contains a simple HTML document with a dynamic greeting that uses the @name instance variable.

To render the Phlex template in our Rails application, we need to update the corresponding controller action to use the render_phlx method instead of the render method. Here's an example of how to update the welcome controller to use the index.phlx template:

class WelcomeController < ApplicationController
  def index
    @name = 'John'
    render_phlx 'welcome/index'
  end
end

In this example, we have updated the index action of the WelcomeController to set the @name instance variable to 'John' and render the index.phlx template using the render_phlx method.

Overall, integrating Phlex into a Ruby on Rails project is a simple process that involves adding the Phlex gem to your Gemfile, creating Phlex templates in the app/views directory, and updating your controller actions to use the render_phlx method to render the templates.

Phlex configuration options in Ruby on Rails

Here are the Phlex configuration options for Ruby on Rails integration with their short explanation:

1. Phlex.config.template_extension: This option sets the file extension for Phlex templates. The default value is .phlx.

2. Phlex.config.template_handler: This option sets the template handler for Phlex templates. The default value is :phlx.

3. Phlex.config.template_paths: This option sets the paths where Phlex will look for templates. The default value is ["app/views"].

4. Phlex.config.default_layout: This option sets the default layout for Phlex templates. The default value is nil.

5. Phlex.config.default_format: This option sets the default format for Phlex templates. The default value is :html.

6. Phlex.config.raise_exceptions: This option sets whether Phlex should raise exceptions when encountering errors. The default value is false.

7. Phlex.config.logger: This option sets the logger for Phlex. The default value is Rails.logger.

8. Phlex.config.cache: This option sets whether Phlex should cache templates. The default value is Rails.env.production?.

9. Phlex.config.cache_dir: This option sets the directory where Phlex should store cached templates. The default value is tmp/cache/phlex.

10. Phlex.config.cache_key_generator: This option sets the cache key generator for Phlex. The default value is Phlex::CacheKeyGenerator.new.

Overall, these configuration options allow developers to customize the behavior of Phlex in their Ruby on Rails applications, from setting the file extension and template handler to configuring caching and error handling.
