The AbstractTransformer class is the base for all Fractal transformers used to serialize resources into JSON:API-compliant responses.

Responsibilities

• Defines how entities are transformed into API responses.
• Implements core serialization logic and extension points for custom fields and relationships.

Key Methods

• create(...$args): Static factory for transformer instances.
• getAvailableMetas(): Returns available metadata fields.
• item($resource): Serializes a single resource.
• collection($resources): Serializes a collection of resources.

Example Usage

class UserTransformer extends AbstractTransformer {
    public function transform(User $user) {
        return [
            'id' => $user->getId(),
            'name' => $user->getName(),
        ];
    }
}

Extension Points

• Extend this class to define custom serialization logic for your entities.
