Usage

Query

• #[Query(name: 'name')]

{
    public function __construct(private readonly ArticleProvider $articleProvider) {}

    /**
     * @return Article[]
     */
    #[Query(name: 'articles')]
    public function __invoke(int $limit, int $offset): array
    {
        return $this->articleProvider->list($limit, $offset);
