AssetsBundle, v3.3.0

NOTE : If you want to contribute don't hesitate, I'll review any PR.

Introduction

AssetsBundle is a module for ZF2 allowing asset management (bundling & caching) like Css, Js and Less, dependent on modules, controllers and actions . This module manages the concept of the "development/production" environment.

In development :

Files are not bundled for easier debugging.
Less files are compiled when updated or if an "@import" inside is updated

In production :

All files are bundled and cached once only if needed.
Assets path are encrypted to mask file tree (with the exception of files in the "assets" directory)

Requirements

Zend Framework 2 (latest master)
lessphp (latest master).
Minify (latest master).

Installation

Main Setup

By cloning project

Install the lessphp fork, Minify by cloning them into ./vendor/.
Clone this project into your ./vendor/ directory.

With composer

Add this project in your composer.json:

"require": {
    "neilime/zf2-assets-bundle": "dev-master"
}

Now tell composer to download AssetsBundle by running the command:
```
$ php composer.phar update
```

Post installation

Enabling it in your application.config.phpfile.

<?php
return array(
    'modules' => array(
        // ...
        'AssetsBundle',
        // ...
    ),
    // ...
);

You should note that as the ordering of modules matters, you should declare the 'AssetsBundle' module before your application modules to ensure the default settings don't take priority.

Insert css & js files into your layout page

Into the <head> part :
```
echo $this->headScript();
```
At the bottom of the <body> part :
```
echo $this->inlineScript();
```

How to use AssetsBundle

Simple configuration example

This example shows how to convert ZF2 Skeleton Application to manage assets via AssetsBundle.

After installing skeleton application, install AssetsBundle as explained above.
Then just create cache directory into "public/".

cd to/your/project/public/dir/
mkdir cache

Edit the application module configuration file module/Application/config/module.config.php, adding the configuration fragment below:

<?php
return array(
    //...
    'assets_bundle' => array(
    	'assets' => array(
			'css' => array('css'),
			'js' => array(
				'js/jquery.min.js',
				'js/bootstrap.min.js'
			),
			'media' => array('img','fonts')
    	)
    ),
    //...
);

Edit layout file module/Application/view/layout/layout.phtml, removing prepend function for assets:

 <?php
//Remove these lines

->prependStylesheet($this->basePath() . '/css/bootstrap-responsive.min.css')
->prependStylesheet($this->basePath() . '/css/style.css')
->prependStylesheet($this->basePath() . '/css/bootstrap.min.css')

 ->prependFile($this->basePath() . '/js/bootstrap.min.js')
 ->prependFile($this->basePath() . '/js/jquery.min.js')

Save & Refresh.

Configuration

The default configuration is setup to run with "Application ZF2 Skeleton"

1. AssetsBundle

boolean production: Define the application environment (development => false). Default true.
mixed lastModifiedTime: (optionnal) Allows you to define an arbitrary asset's last modified time in production. Default null : last modified time is calculated for each asset.
string basePath : (optionnal) only needed if cacheUrl use @zfBaseUrl. If undefined, \Zend\Http\PhpEnvironment\Request::getBasePath() is used.
string cachePath : cache directory absolute path, you can use the @zfRootPath constant corresponding to current working directory. Default @zfRootPath/public/cache.
string configCachePath : configuration cache directory absolute path, you can use the @zfRootPath constant corresponding to current working directory. Default @zfRootPath/data/cache.
string assetsPath : (optionnal) assets directory absolute path, allows you to define relative path for assets config. You can use the constant @zfRootPath corresponding to current working directory. Default @zfRootPath/public.
string cacheUrl : cache directory base url, you can use the constant @zfBaseUrl corresponding to application base url . Default @zfBaseUrl/assets/cache/.
array mediaExt : Put here all medias extensions to be cached. Default array('jpg','png','gif','cur','ttf','eot','svg','woff').
boolean recursiveSearch: If you define a folder as required asset, it will search for matching assets in that folder and its subfolders. Default false.

2. Assets

You can define assets for modules / controllers / action

Exemple :

   <?php
   return array(
           //...
           'assets_bundle' => array(
               //...
   	        'assets' => array(
   			//Common assets included in every pages
   			'css' => array(), //Define css files to include
   			'js' => array(), //Define js files to include
   			'less' => array(), //Define less files to include
   			'media' => array(), //Define images to manage

   			//Modules specific assets
   			'Test' =>  => array( // "Test" is the name of the module

   				'css' => array(),
       			'js' => array(),
       			'less' => array(),
       			'media' => array(),

       			//Controller specific assets
       			'Test\Controller\Name' => array(
       				'css' => array(),
   	    			'js' => array(),
   	    			'less' => array(),
   	    			'media' => array(),

   	    			//Action specific assets
   	    			'ActionName'=> array(
   	    				'css' => array(),
   		    			'js' => array(),
   		    			'less' => array(),
   		    			'media' => array()
       				),
       				//...
       			),
       			//...
       		),
       		//...
   		    )
           ),
           //...
       ),
       //...
   );

For each asset, you can specify files or directories. All these elements are related to the asset path by default, but you can specify an absolute path or use the constants "@zfAssetsPath" and "@zfRootPath". If you specify a directory, all files matching the asset type (css, less, js, media) will be included.
You can use .php files as assets, there will be interpret.

You can use url for js and css assets :

<?php
    return array(
        //...
        'assets_bundle' => array(
            //...
            'assets' => array(
                'js' => array('http://ajax.googleapis.com/ajax/libs/mootools/1.4.5/mootools.js'),
                //...
            )
            //...
        )
        //...
    );

This example includes Mootools from Google Hosted Libraries

You can define an inclusion order like this :

<?php
    return array(
        //...
        'assets_bundle' => array(
            //...
            'assets' => array(
                'js' => array('js/firstFile.js','js'),
                //...
            )
        )
        //...
    );

This example includes the file "firstFile.js" first, and all other javascript files in the folder "js"

3. Custom Js

This function allows you to dynamically include javascript files. For exemple, files specific to user settings. In this case, your controller that need these file have to extend AssetsBundle\Mvc\Controller\AbstractActionController.

Attention ! Jscustom process does not cache javascript, due to performance reasons

Then create a jscustomAction function into your controller :

public function jscustomAction($sAction = null){
	//Check params, it's not mandatory
	if(empty($sAction)){
		$sAction = $this->params('js_action');
		if(empty($sAction))throw new \InvalidArgumentException('Action param is empty');
	}

	$aJsFiles = array();
	switch(strtolower($sAction)){
		case 'myActionName':
			//Put here all js files needed for "myActionName" action
			$aJsFiles[] = 'js/test.js';
			$aJsFiles[] = 'js/test.php';
			break;
	}
	return $aJsFiles;
}

Edit layout file:

//Into head

//Production case
if(!empty($this->jsCustomUrl))$this->plugin('InlineScript')->appendFile($this->jsCustomUrl.'?'.time()); //Set time() force browser not to cache file, it's not mandatory
//Development case
elseif(is_array($this->jsCustomFiles))foreach($this->jsCustomFiles as $sJsCustomFile){
	$this->plugin('InlineScript')->appendFile($sJsCustomFile);
}
