A customized Copy of react-loadable/babel plugin

This is a replica of react-loadable's babel plugin.

Notable Differences:

1. Removed flow based personal preference.
2. Added an option source to specify the name of the imported library, defaults to "react-loadable".
3. Split into a seprate repository as this is a development dependency, while the main library is not.

install

if you are using react-loadable/babel this is not needed because sadly the plugin is baked inside the library.

``
yarn add --dev react-make-async-babel-plugin
`

Babel Plugin

Included in the react-loadable package is a Babel plugin that can add
serverSideRequirePath and webpackRequireWeakId for you.

Input:

`js
import Loadable from 'react-loadable';

Loadable({
loader: () => import('./MyComponent'),
LoadingComponent: () => null,
});
`

Output:

`js
import _path from 'path';
import Loadable from 'react-loadable';

Loadable({
loader: () => import('./MyComponent'),
LoadingComponent: () => null,
serverSideRequirePath: _path.join(__dirname, './MyComponent'),
webpackRequireWeakId: () => require.resolveWeak('./MyComponent'),
});
`

#### Plugin Setup

If you have react-loadable installed already, all you need to do is add this
plugin to your Babel config:

`js
{
plugins: [
["react-make-async-babel-plugin", {
server: true,
webpack: true
}]
]
}
`

Options:

- server (default: true) - When true adds serverSideRequirePath config.
- webpack (default: false) - When true adds webpackRequireWeakId config.
- source (default: react-loadable`) - match against the library name to add the properties to its configs object.
