Install

note: You need PHP5 (because of class.JavaScriptPacker.php)

1. get archive with jscsscomp

2. extract archive somethere on your disc

3. copy jscsscomp folder to the document root of your site

5. jscsscomp/cache/ dir should be writable for your scripts (or caching will not work)

6. add this code to the .htaccess file in doc root

RewriteEngine on
	
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.*\.)(js|css)$ jscsscomp/jscsscomp.php?q=$1$2 [L,NC]

or simply copy one from the distribution

From this point all your JS and CSS files should be served compressed by gzip (if browser accepts gzip compression) or by packer (only for JS files)

One file trick

(this part is copied from here)

If you use a lot of JS (or CSS) files

<!-- Namespace source file -->  
<script src = "yahoo.js" ></script> 
 
<!-- Dependency source files -->  
<script src = "dom.js" ></script> 
<script src = "event.js" ></script> 
<script src = "effects/dragdrop.js" ></script> 
 
<!-- Slider source file -->  
<script src = "slider.js" ></script>    

you can get all this files (compressed!) in one request:

<script src = "/jscsscomp/yahoo.js, dom.js, event.js, effects/dragdrop.js, slider.js"></script>

note: i guess you understand what mixing .css and .js files in one request is not a good idea... (;

Doing without ModRewrite

If mod-rewrite is not installed, or you can't use it, write URLs in this way:

<script src = "/jscsscomp/jscsscomp.php?q=dom.js" ></script> 

<script src = "/jscsscomp/jscsscomp.php?q=yahoo.js, event.js, effects/dragdrop.js, slider.js"></script>
