Yii 1.1: dynamicres

Compresses several CSS or JS in a single file (compressed) to minimize number of requests and maximize performance

Dynamic Res

Compress CSS or JS files in only one file to increase performance and decrease request of many files. This extension (version > 1.3) use CssMin and JavaScriptPacker to compress.


assetManager (native)


  • Dowload the extension and put correctly in the extension folder
  • Add the following lines in your configuration file:

main.php 'components'=>array(

            'class' => 'application.extensions.DynamicRes.DynamicRes',
            'urlConfig' => array( // Its fix Css, and convert Url to RealName 
                'baseUrl'  => '/', // Url of your Site (ending with /), modify it if you use subdomain
                'basePath' => dirname(__FILE__).'/../../', // path of your site (ending with /) (No Change This)

In your layouts puts

    <?php Yii::app()->dynamicRes->registerCssFile(Yii::app()->request->baseUrl . '/css/style.css'); ?>
    <?php Yii::app()->dynamicRes->registerCssFile(Yii::app()->request->baseUrl . '/css/reset.css'); ?>
    <?php Yii::app()->dynamicRes->registerCssFile(Yii::app()->request->baseUrl . '/css/common.css'); ?>
<?php Yii::app()->dynamicRes->saveScheme(); // use This function on end of layout or use on afterRender of your Controller Class (Auto SaveScheme) ?>

Remember, Do not save scheme again in your views or other files

Auto SaveScheme

to facilitate, you can call the function saveScheme on function "afterRender" of controller. Example:

class Controller extends CController {    
    protected function afterRender($view, &$output) {

Cache and Compress with GZIP

All files are placed in your asset folder, to cache use htaccess. (do not worry about the name of the files, they are switched when the original file is modified). Example of cache:

<FilesMatch "\.(js|css)$">
    Header set Expires "Sun, 15 Feb 2020 20:00:00 GMT"


<ifModule mod_gzip.c>
  mod_gzip_on Yes
  mod_gzip_dechunk Yes
  mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$
  mod_gzip_item_include handler ^cgi-script$
  mod_gzip_item_include mime ^text/.*
  mod_gzip_item_include mime ^application/x-javascript.*
  mod_gzip_item_exclude mime ^image/.*
  mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*


<ifModule mod_expires.c>
  ExpiresActive On
  ExpiresDefault "access plus 1 seconds"
  ExpiresByType text/html "access plus 1 seconds"
  ExpiresByType image/gif "access plus 2592000 seconds"
  ExpiresByType image/jpeg "access plus 2592000 seconds"
  ExpiresByType image/png "access plus 2592000 seconds"
  ExpiresByType text/css "access plus 604800 seconds"
  ExpiresByType text/javascript "access plus 216000 seconds"
  ExpiresByType application/x-javascript "access plus 216000 seconds"

not working

I tried to combine several js files but it's not working. Moreover, the html position of the generated js file is in the HEAD tag, and I would like to be just before de end of the BODY tag. Furthermore, Yii::app()->dynamicRes->registerCoreScript('jquery') is not supported

Ingwie Phoenix at 2014/09/18 06:17am

This extension turned 5-6 script and link tags into one! However, I am still facing a few problems...

For one, when I minify socket.io.js, I get a JS error int he console about an unexpected token. Also with pick-a-color-1.2.3.min.js.

Is there a way to add configuration options to DynamicRes to:

  • Determine which files are idneed minified before added to the "big file"?
  • Change the JS packer individually or generally?

You could look at http://www.yiiframework.com/extension/escriptboost/ for some good JS packers. This extension does not provide a register{...}File set of functions, which is why i am using DynamicRes and EScriptBoost side-by-side.

I also have another problem about CSS. I am using WingStyle ( https://github.com/IngwiePhoenix/WingStyle ) to generate my main CSS. I didn't figure out a good way to "automatically generate and update" a static CSS from it, yet. So is there an option to append a CSS file to the array verbatim, without it getting either minified or even added to the big file?

You can see my current code for this here: http://git.ingwie.me/ingwie/bird3/blob/master/protected/components/Controller.php

Would be great if you could help me out here ^_^ Kind regards, Ingwie.

Compress JS files Used by YII and Extensions

Wow, this extension has sped up my site (+1). Thanks for sharing it.

Can I also use this extension to compress these JavaScript files used by Yii and extensions?

For example: jquery.min.js, jquery.yii.js, query.yiigridview.js, etc.

Thanks, Jay.

Wrong Config

You need to config Url Base of Your Site, your baseUrl is "/yii/escorifa/"

'urlConfig' => array( // Its fix Css, and convert Url to RealName 
                'baseUrl'  => '/yii/escorifa/', // Url of your Site (ending with /), modify it if you use subdomain
                'basePath' => dirname(__FILE__).'/../../', // path of your site (ending with /) (No Change This)

Upgrade to "DynamicRes 1.5" and use function debug();

<?php Yii::app()->dynamicRes->debug(); ?>

use this after include yours files (in your view)

One more thing...

I found bug in registerScriptFile(), but it's already fixed. Nice. :) But there is something wrong with CssMin - maybe because my example was for CssMin 2.0.1 and you are using CssMin 3.0 (didn't know it is out), so entire script breakes. You have to change line 106 to this:

return CssMin::minify($content, array(), array('CompressUnitValues' => true));

BTW have you ever tested JavaScriptPacker for large files? I've tried a lot of libraries and some of them (JsMin+) caused memory leak while processing big files. Don't have time to try this now, maybe someone else will test.

Bug Fixed (Version 1.3)

Fixed bug in "registerScriptFile"

compress of css is using "CssMin" compress of js is using "JavaScriptPacker"

#4815 report it
Pomstiborius at 2011/08/18 04:54pm

I will test it tomorrow and see if there are any other bugs. :)

About CssMin - it is really simple.

function minify($code) {
    return CssMin::minify($code, array('compress-unit-values' => true));

As you see you only need to include CssMin file and call CssMin::minify($code, $options) function. You may want to check out $options, but that's all.

Thanks, bug in parserCss is fixed now

I will study this CssMin to replace compress
