Add Your Own Dependencies and Packages

Pimcore manages itself all dependencies using composer and therefore you can add your own dependencies by using standard composer functionalities.

Basic Example

Use composer in your project root directory, eg.

composer require mtdowling/cron-expression

Third party bundles

You can install third party bundles via composer as shown above (as Pimcore is a standard Symfony application, you should be able to use any third-party Symfony bundle).

To load a bundle with the application, it must first be enabled in config/bundles.php (see bundles documentation). As Pimcore defines a registerBundles method base Kernel class, which is returns a list of default bundles and priority can be important for config auto loading, the Pimcore Kernel exposes a registerBundlesToCollection method which allows to add bundles to a BundleCollection with an optional priority (higher priority is loaded first) and a list of environments to handle (e.g. load only in dev environment).

Bundles without a priority are registered with a default priority of 0. You can set a negative value if you need to set a priority lower than default.

As an example, register a third party bundle on the collection:

<?php

namespace App;

use Pimcore\HttpKernel\BundleCollection\BundleCollection;
use Pimcore\Kernel as PimcoreKernel;

class Kernel extends PimcoreKernel
{
    /**
     * Adds bundles to register to the bundle collection. The collection is able
     * to handle priorities and environment specific bundles.
     */
    public function registerBundlesToCollection(BundleCollection $collection): void
    {
        if (class_exists('\\XYZBundle\\XYZBundle')) {
            $collection->addBundle(new \XYZBundle\XYZBundle);
        }

        // add a custom third-party bundle here with a high priority and only for dev environment
        $collection->addBundle(new Third\Party\PartyBundle, 10, ['dev']);
    }
}

You can read more about the bundle collection and handling of dependencies in Bundle Collection.

Pimcore Bundles

For more information see Pimcore Bundles.

Just like third party bundles, Pimcore bundles can be registered on the kernel by enabling them in the config/bundles.php or manually by adding them via code as shown above. You can use pimcore:bundle:* commands to list or interact with the bundle installer (install/uninstall/update).
