This library adds CommonJS support to Sprockets.
This is a fork, since the original was not published for ages.
Also this includes the changes from wazeHQ/sprockets-commonjs to allow you transparent requires without the .module
-part in filename.
in Gemfile
gem 'sprockets-commonjs-mindreframer'
install
$ bundle install
What is CommonJS?
The CommonJS module format is a way of encapsulating JavaScript libraries, ensuring they have to explicitly require and export properties they use. In a nutshell:
-
You require in files using require()
:
var Asset = require('models/asset');
-
You export properties using module.exports
:
var Asset = function(){ /* ... */ };
module.exports = Asset;
This library
This library adds CommonJS support to Sprockets, so it can wrap up JavaScript files as modules, and serve them appropriately.
This is done transparently by checking for require('...')
or module.exports = ...
-statements in the source-code.
Sprockets will then wrap up the JS library when it's requested, with the following:
require.define({'library/name': function(exports, require, module){ /* Your library */ }});
require.define()
is defined inside commonjs.js
, which will be included, if any CommonJS modules were found.
One caveat to the approach this library takes, is that dependencies loaded through require()
will not be added to the dependency graph. This library will not parse the AST tree for require calls. This decision has been made for a variety of reasons, but it does mean you need to require files through both CommonJS and Sprockets.
Usage
-
Add gem 'sprockets-commonjs-mindreframer'
to your Gemfile
-
Configure Sprockets::CommonJS.module_paths, e.g.:
Sprockets::CommonJS.module_paths += [Rails.root.to_s]
-
Require all the modules, e.g.: //= require_tree ./models
-
Or, require individual modules, e.g.: //= require users
