System.js async loader plugin

README.md

Usage

To asynchronously load Google maps:

config.js:

System.config({
	"paths": {
		"maps": "google-maps-url"
	}
});

bootstrap.js:

import 'maps!async';

Note: The google global won't be available until it calls a callback included in the URL.

async.js

var inject = (src) => {
	var script, target;

	// Create script> linking to async source
	script = document.createElement('script');
	script.type = 'text/javascript';
	script.async = true;
	script.src = src;

	// Injects as first <script>
	target = document.getElementsByTagName('script')[0];
	target.parentNode.insertBefore(script, target);
};

export var fetch = (load) => {
	inject(load.address);

	// Required to return a string, we're faking that we fetched a file and now we're returning it to SystemJS
	return '';
};
