JavaScript today is capable of generating a lot of data. The easiest way to deliver multiple files to your users is in a zip file. Instead of wasting server resources and bandwidth you can get the client to do it for you.

Is it simple and easy, you ask? Yes, definitely. Look at the example code below:

zip = new JSZip();
zip.add("Hello.", "hello.txt");
Downloadify.create('downloadify',{
...
  data: function(){
    return zip.generate();
  },
...
  dataType: 'base64'
});
