CSS-JS-Booster

Description

CSS-JS-Booster is a PHP-script that tries to automate as many performance
optimizing steps related to CSS and JS embedding as possible.
Depending on the amount of CSS, CSS-images and JS, this can significantly
increase loading speed of your site.

Note: Check by hand the htaccess-part! (see “Installation”)

For CSS optimization steps are:

  • combine multiple CSS-files resulting in less HTTP-requests
  • Optimize and minify CSS with CSSTidy
  • Embed any CSS-images smaller 24KB as data-URI or MHTML (for IE <= 7)
  • GZIP-compress the resulting CSS
  • Have browsers cache the result as long as it remains unchanged
  • If IE6: Issue a JS-command to fix background image caching behaviour

For JS optimization steps are:

  • Fetch JS from external servers and cache it locally
  • Combine multiple JS-files resulting in HTTP-requests going down
  • GZIP-compress the resulting JS
  • Have browsers cache the result as long as it remains unchanged

Support

Please send bug reports this way: http://github.com/Schepp/CSS-JS-Booster/issues

When creating a new issue:

  • Make sure that you mention in the title that you are talking about the WordPress plugin (as there is a standalone version, too), e.g.: “[WP] Booster killed my site”
  • Make sure that you send me a link to your page
  • Tell me what exactly is broken
  • It helps if you put the HTML source code of your page resulting from activated Booster on http://pastebin.com/ and include a link to it
  • It helps if you put the HTML source code of your page resulting from deactivated Booster on http://pastebin.com/ and include a link to it
  • It helps if you tell me which plugins are active

Installation

CSS-JS-Booster absolutely requires PHP 5. No PHP 4, sorry…
Version-wise it is tested up until PHP 5.3.

  • Copy the whole booster-folder into wp-content/plugins/
  • If not already there: create a subfolder named booster_cache inside wp-content/ and CHMOD it to 0777 (give it write-permissions)
  • Go into the admin-panel to the plugins and activate CSS-JS-Booster
  • Check if the contents of the file wp-content/plugins/booster/htaccess/.htaccess were put into/appended to the .htaccess-file in the root of your WordPress-site. If not append them by hand.

Compatibility with other plugins

CSS-JS-Booster may in rare cases break some other plugins.
I noticed for example that plugins trying to calculate file-paths based on the src-attribute of the script-tag break.
So you need to check yourself.

If your site has many visitors, we suggest that you combine CSS-JS-Booster with WP-Super-Cache.
