Packer – Javascript compressor

Oct

I tried ‘packing’ an already minimized version of JQuery (which was about 55KB) and this compressed it to about 30KB (almost 50% less). My advice – don’t publish any javascript without pumping it through this first!

Some tips:

  • Packer obfuscates code, so it makes things very difficult to debug. If you end up having problems with compressing the code, try compressing sections at a time to find out what’s causing the problem.
  • Write code so that it doesn’t rely on whitespace or line-breaks. Use braces instead.
  • Don’t forget your semi-colons. (Especially when declaring anonymous functions for example)
