HTML5 has an async attribute for script files, to enable async loading.
<script type="text/javascript" src="myScript.js" async></script> I can take advantage of this with my MVC4 bundling by referencing the bundle like so.
<script type="text/javascript" src='@Scripts.Url("~/bundles/jquery")' async></script> But what this does mean is my scripts are bundled even when in debug mode.
So how can I take advantage of bundling and the async attribute without loosing non-minification when in debug.

Bundling and minification are two techniques you can use in ASP.NET 4.5 to improve request load time. Bundling and minification improves load time by reducing the number of requests to the server and reducing the size of requested assets (such as CSS and JavaScript.)
Both bundling and minification are the two separate techniques to reduce the load time. The bundling reduces the number of requests to the Server, while the minification reduces the size of the requested assets.
Bundling and Minification are two performance improvement techniques that improves the request load time of the application. Most of the current major browsers limit the number of simultaneous connections per hostname to six.
BundleConfig.cs Shown below is the BundleConfig. cs file present in a default MVC5 application. This file contains RegisterBundles() method which is being called at Application_Start() event by global. asax.
If you upgrade to the 1.1-alpha1 release, you can just add the async attribute to the tag format either via:
Scripts.DefaultTagFormat = @"<script src=""{0}"" async></script>" or passing it where you want the async tag
Use following instead of Scripts.Render("~/bundles/jquery")
Scripts.RenderFormat(@"<script src=""{0}"" async></script>", "~/bundles/jquery") If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
