CDN PHP Symfony Bundle

A Symfony Bundle for CDN PHP.

Installation

Make sure Composer is installed globally, as explained in the installation chapter of the Composer documentation.

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

composer require babeuloula/cdn-php-bundle

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

// config/bundles.php

return [
    // ...
    BaBeuloula\CdnPhpBundle\CdnPhpBundle::class => ['all' => true],
];

Step 3: Configure the Bundle

# config/packages/cdn_php.yaml

cdn_php:
    proxy:
        assets_path: 'mandatory'
        url: 'mandatory'
        check_assets: true # if the bundle needs to check if you have the file on the server before fetch from CDN PHP
        encrypted_parameters: false # if you need to hide the query parameters on your application
    encrypter:
        secret_key: null # Signs URLs generated by cdn_php() / cdn() Twig functions (app → browser).
                         # Used to prevent tampering with query parameters on the public-facing proxy route.
                         # Algorithm: SHA1(query_string + secret_key). Validated by Signer::isValid().
                         # Required when proxy.encrypted_parameters is true.
        cdn_secret_key: null # Signs requests sent by Proxy to the CDN PHP service (app → CDN).
                             # Must match the SIGNATURE_SECRET environment variable set on the CDN PHP instance.
                             # Algorithm: HMAC-SHA256(imageUrl:expires, cdn_secret_key).
                             # Leave null if CDN PHP runs without SIGNATURE_SECRET.
        cdn_expires_ttl: 3600 # Validity duration (in seconds) of CDN request signatures.
                              # Only used when cdn_secret_key is set. Default: 3600 (1 hour).
    twig:
        route_name: 'mandatory' # the route to the controller that displays the assets
        route_parameter: 'mandatory' # the route parameter name

Using a fallback handler

If you don't have access to CDN PHP or if you want to use it on local development, you can set up a fallback handler.

Actually, I only support Intervention Image v3.

Intervention\Image\Drivers\Imagick\Driver: ~

BaBeuloula\CdnPhpBundle\FallbackHandler\InterventionImageFallbackHandler:
    arguments:
        $assetsPath: '_your_path_'
        $driver: '@Intervention\Image\Drivers\Imagick\Driver'
        $cache: '_your_cache_instance_'

BaBeuloula\CdnPhpBundle\FallbackHandler\FallbackHandlerInterface: '@BaBeuloula\CdnPhpBundle\FallbackHandler\InterventionImageFallbackHandler'
