babel-plugin-compact-reexports

Allows ES modules which just re-export contents of other modules to be more compact; saving you bytes over the wire.

This plugin is designed to work with loader.js, but could work with any AMD loader that supports a similar alias API.

What It Does

Given a re-export module:

// my-module.js
export { default } from 'their-module';

When using AMD, this would normally compile to something like:

define('my-module', ['exports', 'their-module'], function (exports, _theirModule) {
  'use strict';

  Object.defineProperty(exports, 'default', {
    enumerable: true,
    get: function get() {
      return _theirModule['default'];
    }
  });
});

Which is pretty verbose for a simple re-export. This plugin will rewrite the above to the following:

define.alias('their-module', 'my-module');
