browserify-async-define

2.1.4 • Public • Published

Note: This is working and battle tested, but I suggest to use either webpack or rollup instead (I explain the reason at the bottom)

browserify-async-define

This browserify plugin can be used to wrap some dependencies using async-define and thus, factor out those in common bundles.

Options:

  • -d --dependsOn "name:label[:filename]" the dependency "name" will come from a different bundle with the label "label". If you add "filename" (optional) this dependency will be bundled in that file.
  • -e --exports "file:label" the module.exports of this file will be exposed with the label "label"
  • --verbose it will output which modules was removed and which stays. Useful to detect if a module is in because of a dependency of a dependency
  • --collapse the requires ids are transformed in numbers instead of strings (more compact bundles)

With the main.js:

var $ = require('jquery');
var $node = $('<div>Hello</div>').appendTo(document.body);

You can build bundle and main like this:

browserify main.js -o dist/main.js -p [browserify-async-define -d jquery:jquery2.2:dist/common.js]

or using the api:

var browserifyAsyncDefine = require('browserify-async-define');
var b = browserify('main.js')
  .plugin(browserifyAsyncDefine, {
    dependsOn: ['jquery:jquery2.2:dist/common.js]
  });

and then load them like this:

<script async src="dist/common.js"></script>
<script async src="dist/main.js"></script>

You can factor out multiple dependencies and use the "label" to express different versions:

browserify main.js -o dist/main.js -p [browserify-async-define -d jquery:jquery20:dist/jquery.js -d react:react014:dist/react.js -d react-dom:reactDom014:dist/react.js]

and then load them like this:

<script async src="dist/jquery.js"></script>
<script async src="dist/react.js"></script>
<script async src="dist/main.js"></script>

async-define will isolate the namespace and allow to use different versions of a package.

peerDependencies

To use this plugin you should also install this package:

"async-define": "latest",

Why avoiding this

async-define has the same interface used by AMD modules. So it was very easy to create a rollup or webpack plugin because they are already able to produce an AMD output of the bundle. This plugin instead is pretty complicated and heavy to maintain. I consider this to be deprecated and only apply the least possible maintenance.
