Improved caching for [Assetic](https://github.com/kriswallsmith/assetic).

Installation
------------

[](#installation)

Jasny's Twig Extensions can be easily installed using [composer](http://getcomposer.org/)

```
composer require jasny/assetic-extensions

```

Internal caching when using a factory
-------------------------------------

[](#internal-caching-when-using-a-factory)

The `AssetCacheWorker` wraps each asset in a asset in an `AssetCache` object. This enables the use of asset caching when using a factory.

```
use Assetic\Factory\AssetFactory;
use Jasny\Assetic\AssetCacheWorker;

$factory = new AssetFactory('/path/to/asset/directory/');
$factory->setAssetManager($am);
$factory->setFilterManager($fm);

$factory->addWorker(new AssetCacheWorker(
    new FilesystemCache('/path/to/cache')
));
```

Versioning assets
-----------------

[](#versioning-assets)

The `AssetVersionWorker` add a version number to each generated assets. This works well on a production environment, preventing the need of removing, checking or overwriting the asset files.

If the output file is set to `all.css` and version is set to `1.3.7`, the output file will be named `all-1.3.7.css`.

```
use Assetic\Factory\AssetFactory;
use Jasny\Assetic\AssetVersionWorker;

$factory = new AssetFactory('/path/to/asset/directory/');
$factory->setAssetManager($am);
$factory->setFilterManager($fm);

$factory->addWorker(new AssetVersionWorker($version));
```

Caching when using Twig
-----------------------

[](#caching-when-using-twig)

With the example code from the Assetic readme, each template is parsed on each request. This considerably slows down your application. The `TwigCachingFormulaLoader` using Twig cache to store the assetic formulae is finds in each template. The formula loader uses the [`cache` and `auto_reload` options](https://twig.sensiolabs.org/doc/2.x/api.html#environment-options)of the Twig environment.

The `PersistentAssetWriter` is an asset writer with an `overwrite` option. When overwrite is disabled, existing assets are not overwritten. This can speed up your production environment. It's recommended to add a version number in the output files, either manually or by using the `AssetVersionWorker`.

```
use Jasny\Assetic\PersistentAssetWriter;
use Jasny\Assetic\TwigCachingFormulaLoader;
use Assetic\Extension\Twig\TwigResource;
use Assetic\Factory\LazyAssetManager;

$twigLoader = new Twig_Loader_Filesystem('/path/to/views');
$twig = new Twig_Environment($twigLoader, ['cache' => '/path/to/cache', 'auto_reload' => true]);

$am = new LazyAssetManager($factory);

// enable loading assets from twig templates, caching the formulae
$am->setLoader('twig', new TwigCachingFormulaLoader($twig));

// loop through all your templates
foreach ($templates as $template) {
    $resource = new TwigResource($twigLoader, $template);
    $am->addResource($resource, 'twig');
}

$writer = new PersistentAssetWriter('/path/to/web');
$writer->writeManagerAssets($am);
```
