// loads and caches the zip file var loader = new ZipLoader('files.zip'); // creates a style node in the document header and appends the style loader.LoadCSS('files.zip://style.css'); // creates a script node in the document header and appends the script loader.loadScript('files.zip://jquery.js'); // returns the file content var someFileYouNeed = loader.load("files.zip://myFile.txt"); // returns the base64 encoded image usable as img source $("#logo").attr('src', loader.loadImage('files.zip://images/logo.png'));
The level of compression using zip surpasses the js and css minification in all the ways possible. For example, My current application has 79 files (js, and few css) and they all sum up to 924KB in size. Zipping all those 96 files using Ultra compression level gives me 1 file of 126 KB => 1 server request. That's something.
The best performance is made Opera (strangely), then Firefox, Crome, Safari and last IE (no surprise here, I was expecting it before I even started).
It's a V 1.0 that still needs some work and it doesn't work in IE because that stupid browser overrides the mime type and at first null character in the reading of the zip, the content ends. I will fix this eventually 🙂 I will also include this as a jClass library soon.
Update: Fixed it so it works in IE as well. There is a performance issue still. Will fix that too.
Till then, HERE are the sources and a demo.
The zip in the demo is made using 7Zip with Ultra Compression level.
