Localscript.js is asynchronous JavaScript loader inspired by Cloudflare Rocket Loader

• Ensures that all the scripts on your page will not block the content of your page from loading
• Loads all the scripts on your page asynchronously
• Uses browser's localStorage to store scripts so they aren't refetched unless necessary

All script tags must have type attribute set to text/localscript

<script type="text/localscript">
console.log('hello from localscript');
</script>

External JavaScript files must have data-src attribute instead of src attribute

<script type="text/localscript" data-src="your.js.min.js"></script>
