Extract the files to the corresponding directories, components/* into compontents/ and extensions/* into extensions/ then configure the config file as described below, now MinifyClientScript will do the rest. :) Please comment if you have comments/suggestions/questions.

Example main.php:

Generate in each request

The extension seems to regenerate css and js in every request.

Is there way to improve it ?

issue homeUrl - baseUrl


In my case the extension does not work (I use Yii ver 1.1.15)

I replace Yii::app()->homeUrl with Yii::app()->baseUrl in MinifyClientScript.php and it works!

Parameter Question

I have simply followed that setup description here and the minification works but the most of the JS code is missing so my app doesn't run well anymore. Beside the embedded coded that has been minified and rendered I have several files in header like

$cs ->registerScriptFile($baseUrl.'/js/json2.js')

Those are all missing and may have been replaced by 2 new generated JS file like this:

But definately is is just a little piece of my JS code inside...

Are there any parameters I could play around and try to fix it?

Maybe you have an idea what goes wrong..?

Btw, the minification could be improved by shortening also variables inside functions e.g. function(response){if(response!='') minified: function(e){if(e!='')

check for file isn't empty

on lines 146,198 and 202 also need ckeck on file size if equal zero byte,ignore publish those files

if(filesize($this->minifyPath . "/$filenames[$media]") > 0){
  $this->registerLinkTag("stylesheet", "text/css", Yii::app()->assetManager->getPublishedUrl($this->minifyPath) . "/$filenames[$media]", $media == "default" ? null : $media);
if ($position===self::POS_HEAD){
if(filesize($this->minifyPath . DIRECTORY_SEPARATOR . "$filenameCore.js") > 0)
  $this->registerScriptFile($publishedMinifyPath . "/$filenameCore.js", $position);
if(filesize($this->minifyPath . DIRECTORY_SEPARATOR . "$filename.js") > 0) {
  $this->registerScriptFile($publishedMinifyPath . "/$filename.js", $position);

I noticed that whenever the content of the compiled JavaScript is empty, there is still a script tag generated, causing an unnecessary http request.

RE: Very slow

Koduc, did you make sure to run this test in production mode? and did you also build the cache beforehand?

Very slow

This extension is VERY slow with twitter bootstrap. Page loaded without extension:

ab -c10 -n500 http://localhost/index.php

Requests per second: 15.56 [#/sec] (mean)

Page loaded with extension:

Requests per second: 0.76 [#/sec] (mean)
