Informations about the package twig-asset-version-extension
Asset Version Twig Extension
Render versioned asset filenames in twig.
Install
Use composer:
require ivoba/twig-asset-version-extensionUsage
In your twig files:
<script src="{{ asset_versioned('/dist/js/script.js') }}"></script>This will render : /dist/js/script.12345.js
Where 12345 is by default the md5 content digest of the file.
The trick is to leave the file with the original filename: /dist/js/script.js
and let the webserver rewrite the url by pattern.
F.e, for the above pattern and apache mod_rewrite you could use:
RewriteRule ^dist/(.+)\.(.+)\.(js|css|png|jpg|gif)$ /dist/$1.$3 [L]For nginx:
location ~* ^.+\.(dist)$ {
rewrite ^(.+)\.(\d+)\.(dist)$ $1.$3 last;

Silex:
Register the Twig Extension:
$app['twig'] = $app->share($app->extend('twig', function ($twig, $app) {
$twig->addExtension(new \Ivoba\AssetVersion\Twig\AssetVersionExtension(new \Ivoba\AssetVersion\Version\Md5ContentAssetVersion(),
new \Ivoba\AssetVersion\Namer\DefaultNamer(),
__DIR__. '/../web'));
return $twig;
}));Symfony:
Add this in your services.xml:
<service id="ivoba_asset_version.version.md5_content"
class="Ivoba\AssetVersion\Version\Md5ContentAssetVersion">
</service>
<service id="ivoba_asset_version.namer.default"
class="Ivoba\AssetVersion\Namer\DefaultNamer">
</service>
<service id="ivoba_asset_version.twig.asset_version_extension"
class="Ivoba\AssetVersion\Twig\AssetVersionExtension">
<argument type="service" id="ivoba_asset_version.version.md5_content"/>
<argument type="service" id="ivoba_asset_version.namer.default"/>
<argument>%asset_dir%</argument>
<tag name="twig.extension"/>
</service>Extend
You can create your own Version or Namer class by implementing their resp. interfaces and pass them to the extension.
F.e if you prefer timestamp as version or a different pattern in the filename.
In the Extension you can add options as 4th parameter, as for now it only offers options['asset.directory'], as standard directory for assets.
