This is a Hello World example application for Chaplin.js packed in a Rails application.

• Using HAML, Sass and CoffeeScript
• Using jQuery, Underscore, Backbone, Chaplin
• Using a local copy of requirejs-rails 0.9.0 with r.js 2.1.1
• Using HAML Coffee as templating engine (see also Haml Coffee Assets)
• The application name is ChaplinExample. You might want to change this and several configuration files before using it.
• Asset precompilation for the production environment works fine – the whole JavaScript will be compiled into one JavaScript file.

This example has a standard Chaplin MVC directory structure:

• assets/javascripts/models
• assets/javascripts/views
• assets/javascripts/controllers
• assets/javascripts/libs

All vendor libraries like jQuery and Backbone are located js/vendor/.

There are two special files which are responsible for the application bootstrap:

• assets/javascripts/hello_world_application.js.coffee
• assets/javascripts/routes.js.coffee

hello_world_application.coffee is the application root class which inherits from Chaplin.Application. It starts up all Chaplin core modules and starts the routing. It is loaded and instantiated in assets/javascripts/application.js.coffee.

routes.coffee contains all application routes which map URLs to controller actions.

Since Chaplin is template-engine agnostic, you have to decide which templating solution you want to use and how you want to load the templates. This example uses HAML Coffee templates. They are automatically compiled and included in assets/javascripts/application.js.coffee.

Chaplin expects that views implement the getTemplateFunction method which needs to return the actual templating function. Since all views in this example use the same templating solution, getTemplateFunction is provided once by two base classes all other views inherit from:

• assets/javascripts/views/base/view.js.coffee
• assets/javascripts/views/base/collection_view.js.coffee

The actual .hamlc template files are located in the assets/templates directory.

To ease the development, this repository also provides application-specific base classes for models, collections and controllers. They inherit from the Chaplin base classes:

• assets/javascripts/models/base/model.js.coffee
• assets/javascripts/models/base/collection.js.coffee
• assets/javascripts/controllers/base/controller.js.coffee

Furthermore, assets/javascripts/lib/support.js.coffee and assets/javascripts/lib/utils.js.coffee demonstrate how to extend the feature testing and utility files of Chaplin.

Last but not least, this example uses a specific Layout class which can be found in assets/javascripts/views/layout.js.coffee.
