JS und CSS Packer mal anders
Eher auf der obskuren Seite der Packer, aber trotzdem spannend was so möglich ist.
if you want to compress JavaScript and CSS you could reverse engineer a packing algorithm in JavaScript or you could use a lossless packing system that is already in use and supported in browsers. In this case the packed format is PNG and the way to unpack it is by using the canvas API’s getImageData() method
What we need to test now is when and if it is worth while to have the unpacking done on the client. Imagine adding your JS and CSS to the end of an image and cropping it in CSS to have all the info you need in an app in a single HTTP request.
