In the second part of the tutorial, we will dive deeper into the Propshaft pipeline and learn how to use it to optimize our assets for even better performance. We will cover topics such as asset compression, caching, and preloading, and provide practical examples of how to implement these optimizations in a Ruby on Rails application. By the end of this tutorial, you will have a solid understanding of the Propshaft pipeline and how to use it to manage and optimize assets in your Ruby on Rails applications.

What is Propshaft?

The Propshaft Assets Pipeline is a powerful tool for managing and optimizing assets in Ruby on Rails applications. It allows developers to easily manage their JavaScript, CSS, and other assets, and optimize them for faster loading times and better performance. The pipeline works by processing and compressing assets, and then serving them to the browser in a way that minimizes the number of requests and reduces the overall size of the page. This results in faster loading times and improved performance for the end user.

The Propshaft pipeline also provides a number of other features, such as asset caching, preloading, and fingerprinting, which further improve performance and make it easier to manage assets in a Ruby on Rails application. With the Propshaft pipeline, developers can easily manage and optimize their assets, without having to worry about the complexities of asset management and optimization. Overall, the Propshaft Assets Pipeline is an essential tool for any Ruby on Rails developer who wants to improve the performance and user experience of their applications.

Why use Propshaft for Assets Pipeline in Ruby on Rails application?

There are several reasons why one should use the Propshaft Assets Pipeline in Ruby on Rails applications. Firstly, the pipeline provides a simple and efficient way to manage and optimize assets, such as JavaScript, CSS, and images. By processing and compressing these assets, the pipeline reduces their size and improves their loading times, resulting in a better user experience. Additionally, the pipeline provides features such as caching, preloading, and fingerprinting, which further improve performance and make it easier to manage assets in a Ruby on Rails application.

Secondly, the Propshaft pipeline is highly customizable and flexible, allowing developers to tailor it to their specific needs. For example, developers can choose which assets to include in the pipeline, how to compress and process them, and how to serve them to the browser. This level of customization ensures that the pipeline can be optimized for each individual application, resulting in the best possible performance.

Finally, the Propshaft pipeline is well-supported and widely used in the Ruby on Rails community. This means that there is a wealth of documentation, tutorials, and resources available to help developers get started with the pipeline and troubleshoot any issues that may arise. Overall, the Propshaft Assets Pipeline is an essential tool for any Ruby on Rails developer who wants to improve the performance and user experience of their applications.

Prerequisites

To complete the "Propshaft Assets Pipeline in Ruby on Rails" tutorial, you will need the following prerequisites:

  1. Basic knowledge of Ruby on Rails: You should have a basic understanding of Ruby on Rails, including how to create a new Rails application, how to create controllers and views, and how to work with the Rails asset pipeline.

  2. Familiarity with JavaScript and CSS: You should have a basic understanding of JavaScript and CSS, including how to write and include these assets in a Rails application.

  3. A text editor or integrated development environment (IDE): You will need a text editor or IDE to write and edit code for your Rails application.

  4. Ruby and Rails installed on your computer: You should have Ruby and Rails installed on your computer, along with any necessary dependencies and libraries.

  5. A web browser: You will need a web browser to test and view your Rails application.

  6. Basic knowledge of the command line: You should have a basic understanding of how to use the command line to navigate your file system, run Rails commands, and start a local server.

Ruby on Rails Propshaft step by step setup and configuration

Integrating the Propshaft Assets Pipeline into a Ruby on Rails project is a straightforward process. The first step is to add the Propshaft gem to your Gemfile and run the bundle install command to install it. Once the gem is installed, you can configure the pipeline in your Rails application by adding the following code to your config/application.rb file:

config.assets.configure do |env|
  env.register_transformer 'text/css', 'text/less', LessTransformer
  env.register_transformer 'text/css', 'text/scss', ScssTransformer
  env.register_transformer 'application/javascript', 'application/ecmascript-6', BabelTransformer
end

This code registers the necessary transformers for the pipeline, including LessTransformer for processing Less files, ScssTransformer for processing SCSS files, and BabelTransformer for processing ECMAScript 6 files.

Next, you will need to configure the pipeline to compress and optimize your assets. To do this, add the following code to your config/environments/production.rb file:

config.assets.js_compressor = Uglifier.new(harmony: true)
config.assets.css_compressor = :sass
config.assets.compile = false
config.assets.digest = true

This code configures the pipeline to use Uglifier for JavaScript compression, Sass for CSS compression, and to enable asset fingerprinting and compilation.

Finally, you will need to include your assets in your Rails application using the asset pipeline. To do this, add the following code to your application layout file:

<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>

This code includes the application.css and application.js files in your layout, which are the main entry points for your CSS and JavaScript assets.

With these steps completed, you should now have the Propshaft Assets Pipeline integrated into your Ruby on Rails project, and your assets should be optimized and ready for production use.

Propshaft configuration options in Ruby on Rails

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

  1. config.assets.configure: This option allows you to configure the asset pipeline by registering transformers and processors for different types of assets.

  2. config.assets.js_compressor: This option specifies the JavaScript compressor to use for compressing JavaScript assets.

  3. config.assets.css_compressor: This option specifies the CSS compressor to use for compressing CSS assets.

  4. config.assets.compile: This option specifies whether assets should be compiled on the fly or precompiled before deployment.

  5. config.assets.digest: This option specifies whether asset fingerprinting should be enabled, which adds a unique hash to the filename of each asset to improve caching.

  6. config.assets.enabled: This option specifies whether the asset pipeline should be enabled or disabled.

  7. config.assets.paths: This option specifies additional paths to search for assets, such as vendor assets or assets in other directories.

  8. config.assets.precompile: This option specifies a list of assets to precompile before deployment, which can improve performance and reduce server load.

  9. config.assets.version: This option specifies the version number of the asset pipeline, which can be used to invalidate cached assets and force clients to download new versions.

Overall, these configuration options provide a high degree of flexibility and customization for the Propshaft Assets Pipeline in Ruby on Rails applications, allowing developers to optimize their assets for performance and improve the user experience.

Conclusion

In conclusion, the Propshaft Assets Pipeline is a powerful tool for managing and optimizing assets in Ruby on Rails applications.
