Manifest Files and Directives in Ruby on Rails
In the assets initalizer (config/initializers/assets.rb) are a few files explicitly defined to be precompiled
# Precompile additional assets.
# application.coffee, application.scss, and all non-JS/CSS in app/assets folder are already added.
# Rails.application.config.assets.precompile += %w( search.js )Clicking "Copy Code" button will copy the code into the clipboard - memory. Please paste(Ctrl+V) it in your destination.

Example
Tthe application.coffee and application.scss are so called 'Manifest Files'. This files should be used to include other JavaScript or CSS assets. The following command are available:
- require <path>: The require directive functions similar to Ruby's own require. It provides a way to declare a dependency on a file in your path and ensures it's only loaded once before the source file.
- require_directory <path>: requires all the files inside a single directory. It's similar to path/* since it does not follow nested directories.
- require_tree <path>: requires all the nested files in a directory. Its glob equivalent is path/**/*.
- require_self causes the body of the current file to be inserted before any subsequent require directives. Useful in CSS files, where it's common for the index file to contain global styles that need to be defined before other dependencies are loaded.
- stub <path>: remove a file from being included
- depend_on <path>' Allows you to state a dependency on a file without including it. This is used for caching purposes. Any changes made to the dependency file will invalidate the cache of the source file
An application.scss file could look like:
/*
*= require bootstrap
*= require_directory .
*= require_self

Example
The application.coffee file. Here with including jquery and Turbolinks:
#= require jquery2
#= require jquery_ujs
#= require turbolinks
#= require_tree .Clicking "Copy Code" button will copy the code into the clipboard - memory. Please paste(Ctrl+V) it in your destination. The code will get pasted. Happy coding from Wikitechy - ruby on rails tutorial - rails guides - ruby rails - rubyonrails - learn ruby on rails - team
If you don't use CoffeeScript, but plain JavaScript, the syntax would be:
//= require jquery2
//= require jquery_ujs
//= require turbolinks
//= require_tree .
