• zendframework/zend-view

Features / Goals

• Simple by adding ?timestamp marker to the end of file e.q. /css/test.css?1234567
• Release idenitify new static files version by given REVISION number e.q. /css/1234/test.css
• Hash build unique marker based on file md5 hash e.q. /css/af34c42/test.css. It allows users to load only changed files.
• Multiple hostnames supports e.q. host1.com, host2.com
• Hash generator

Installation

Main Setup

With composer

1. Add this project and Cdn in your composer.json:

   "require": {
       "necromant2005/cdn": "*",
   }

2. Now tell composer to download TweeCdn by running the command:

    'modules' => array(
        // ...
        'TweeCdn',
    ),
    // ...
);
```

Advanced configuration

• type - cdn type
• public_dir - path to public dir
• hostnames - list available hostnames
• hashes - hash list (file_path => hash)
• mapping - map specific to filepath to global CDNs: Google/NetDNA/MaxCDN

Options hostnames - support ALL cdn helpers.

1. Simple (default mode) Simple adds ?timestamp marker to the end of file Original

       /css/simple.css

   tranfromed to

       /css/simple.css?1353231966

   Configuration with mapping jquery to google CDN (https://developers.google.com/speed/libraries/devguide)

   <?php
   return array(
       'di' => array(
           'instance' => array(
               'TweeCdn\View\Helper\Cdn' => array(
                   'parameters' => array(
                       // simple configuration
                       'type'    => 'simple',
                       'options' => array(
                           'public_dir' => __DIR__ . '/../../../../public',
                           'mappings' => array(
                               '/js/jquery.js' => '//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js'
                           ),
                       ),
                   ),
               ),
           ),
       ),
   );

2. Release Release based helper puts release number stored in file "/RELEASE" right after first folder name. As result you have unique path every release. (RELEASE file by default created by Remote multi-server automation tool - Capistrano) Original

       /css/simple.css

   tranfromed to

       /css/1353231966/simple.css

   Configuration

   <?php
   return array(
       'di' => array(
           'instance' => array(
               'TweeCdn\View\Helper\Cdn' => array(
                   'parameters' => array(
                       // simple configuration
                       'release'    => 'release',
                       'options' => array(
                           'public_dir' => __DIR__ . '/../../../../public',
                           'release' => trim(file_get_contents(__DIR__ . '/../../../../REVISION')),
                       ),
                   ),
               ),
           ),
       ),
   );

3. Hash Hash provides almost the same to "release" but uses unique file content hash. It can works in 2 mode:

   • dynamic - when hashed generates in fly
   • pre-compiled - by using existed hash map For "pre-compiled" mode you can generate hash map files by using script. it creates tmp/hashes.php files list. Eventully it makes application faster because you make less IO disk by skiping files md5 calculation every request.

   Original

       /css/simple.css

   tranfromed to

       /css/72e7d8fb348a326251c37821d1b6bfe16ea69d6e/simple.css

   Configuration sample with fail-back protection of missed tmp/hashes.php file and hostnames. The files will be spreaded by cdn-0 and cdn-1 by random depends on filename.

   <?php
   return array(
       'di' => array(
           'instance' => array(
               'TweeCdn\View\Helper\Cdn' => array(
                   'parameters' => array(
                       // simple configuration
                       'release'    => 'hash',
                       'options' => array(
                           'public_dir' => __DIR__ . '/../../../../public',
                           'hostnames' => array('http://cdn-0.coockieless.domain.com', 'http://cdn-1.coockieless.domain.com'),
                           'hashes' => (file_exists(__DIR__ . '/../tmp/hashes.php')) ? include __DIR__ . '/../tmp/hashes.php' : array(),
                       ),
                   ),
               ),
           ),
       ),
   );
