vBulletin JS Min

August 8th, 2007 Leave a comment Go to comments

I realized today that vBulletin’s Javascript was just too bulky and didn’t really need to be, especially when you have no plans to customize it yourself. So I grabbed all the packages of 3.6.x and minimized all the Javascript. In most cases the Javascript files are 50% of the original, which saves bandwidth and speeds up the loading of your forum.


  • Backup all the .js files from the clientscript directory under your forum root.
  • Copy the files from zip file that matches your version of vBulletin into the clientscript directory.
  • Done!

    So you removed whitespace, which is what gzip and mod_deflate do? You rock, clearly.

    RandomCoder: Thanks for your sarcastic comment. That’s not what gzip and mod_deflate do, they compress it further. The problem with using gzip or mod_deflate on JS is a lot of the older browsers have problems uncompressing it at the other end. IE6 is a prime example and a lot of people still use it.

    Installed the modified js files and on my poor 56 k connection, I do feel the difference. Using FF on a Macintel for the records. Guess the slower your connection to the net, the more you’ll feel it. And for the website owner less bandwidth usage. Beneficial to all

    Hey Noodles, just curious what tool are you using to clean the JS? I have tried a few to optimize varoius JS and it breaks the code.

    I’m using a program called jsmin


    I’ve tried a few different programs as well and this one is the only one that didn’t break things.

    EXCELLENT thanks Noodles your a legend. I just tried it on a (non-vB) JS file that everything else breaks, and it worked!

    Also thanks for your vB 3.6.8 JS pack, it definately decreases load times.. Good job!
