Doctrine ORM GraphQL

Metadata¶

This library uses metadata that can be modified with the BuildMetadata event. Modifying the metadata is an advanced feature.

The metadata is an array with a key for each enabled entity class name. See this unit test https://github.com/API-Skeletons/doctrine-orm-graphql/blob/10.2.x/test/Feature/Metadata/CachingTest.php

Caching Metadata¶

The process of attributing your entities results in an array of metadata that is used internal to this library. If you have a very large number of attributed entities it may be faster to cache your metadata instead of rebuilding it with each request.

use ApiSkeletons\Doctrine\ORM\GraphQL\Driver;
use ApiSkeletons\Doctrine\ORM\GraphQL\Metadata;

$metadata = $cache->get('GraphQLMetadata');

if (! $metadata) {
    $driver = new Driver($entityManager);

    $metadata = $driver->get('metadata');
    $cache->set('GraphQLMetadata', $metadata->getArrayCopy());
} else {
    // The second parameter is the Config object
    $driver = new Driver($entityManager, null, $metadata);
}
