SprocketsChain is a small node.js utility that parses Sprockets require directives and returns the dependency chain
for a JavaScript bundle, which is a list of the file paths that make the bundle, ordered so that each file is preceded
by all its dependencies.
Sprockets is very nice for managing assets and their dependencies in a Ruby project. When testing JavaScript though,
precompiling and bundling assets is slow and not really needed. It is more efficient to just require the separate
JavaScript/CoffeeScript source files in the correct order. SprocketsChain parses the require directives and provides
you with the correct ordered list of absolute file paths. This helps setting up a JavaScript test suite that is fast and
completely independent from the Ruby application environment.
var SprocketsChain = require("sprockets-chain");
var sc = new SprocketsChain();
// Append paths to the list of load paths
sc.appendPath("app/assets/javascript");
sc.appendPath("lib/assets/javascript");
sc.appendPath("vendor/assets/javascript");
// If necessary, append extensions (defaults are ".js", ".coffee")
sc.appendExtensions(".ejs", ".eco");
// Get ordered array of individual absolute file paths that compose the
// `application.js` bundle
var chain = sc.depChain("application.js");The following Sprockets directive are supported: require, require_self, require_directory, require_tree
and include
