## Quick Reference

### Installation

### Basic Package with Versioning

```php
use Symfony\Component\Asset\Package;
use Symfony\Component\Asset\VersionStrategy\StaticVersionStrategy;

$package = new Package(new StaticVersionStrategy('v1'));

echo $package->getUrl('/image.png');  // /image.png?v1
```

### JSON Manifest (Webpack / Vite)

```php
use Symfony\Component\Asset\Package;
use Symfony\Component\Asset\VersionStrategy\JsonManifestVersionStrategy;

$package = new Package(new JsonManifestVersionStrategy(__DIR__.'/rev-manifest.json'));

echo $package->getUrl('css/app.css');
// build/css/app.b916426ea1d10021f3f17ce8031f93c2.css
```

### Path-Based Package

```php
use Symfony\Component\Asset\PathPackage;
use Symfony\Component\Asset\VersionStrategy\StaticVersionStrategy;

$package = new PathPackage('/static/images', new StaticVersionStrategy('v1'));

echo $package->getUrl('logo.png');  // /static/images/logo.png?v1
```

### CDN / URL Package

```php
use Symfony\Component\Asset\UrlPackage;
use Symfony\Component\Asset\VersionStrategy\StaticVersionStrategy;

$package = new UrlPackage(
    'https://cdn.example.com/assets/',
    new StaticVersionStrategy('v1')
);

echo $package->getUrl('/logo.png');  // https://cdn.example.com/assets/logo.png?v1
```

### Multiple CDNs

```php
$urls = [
    'https://static1.example.com/',
    'https://static2.example.com/',
];
$package = new UrlPackage($urls, new StaticVersionStrategy('v1'));
```

### Named Packages

```php
use Symfony\Component\Asset\Packages;

$packages = new Packages(
    new Package(new StaticVersionStrategy('v1')),
    [
        'img' => new UrlPackage('https://img.example.com/', new StaticVersionStrategy('v1')),
        'doc' => new PathPackage('/documents', new StaticVersionStrategy('v1')),
    ]
);

echo $packages->getUrl('/main.css');             // /main.css?v1
echo $packages->getUrl('/logo.png', 'img');      // https://img.example.com/logo.png?v1
```
