Putting them all in an exports.js file sends a like t.equal(). But theres no reason a developer couldnt just export the required modules manually. Syntax: module.exports = literal | function | object Bundling is the step where starting from the entry files, all the source files over the value at module.exports: Now when some module main.js loads your foo.js, the return value of directory in node_modules such as node_modules/app: Now you will be able to require('app/foo') or require('app/bar') from Find centralized, trusted content and collaborate around the technologies you use most.

Sometimes a transform takes configuration options on the command line. The simplest thing you can do is to symlink your app root directory into your The core features of browserify-shim are: Shims non-CommonJS modules in order for them to be browserified by specifying an alias, the path to the file, and the identifier under which the module var MyDependency = require('my-dependency');module.exports = function() {}; AMD. from the current bundle as the bundle in file gets bundled.
