Description: A type directive is a special instruction that modifies the behavior of a type in GraphQL. These directives allow developers to customize how data types are handled, providing a way to add metadata or alter the execution of queries. Type directives are defined in the GraphQL schema and can be applied to object types, interfaces, unions, and inputs. Their use is fundamental for extending GraphQL functionality, enabling the creation of more flexible APIs tailored to the specific needs of applications. For example, they can be used to indicate that a field is optional or to apply specific validation rules. Type directives are a powerful tool that helps developers manage the complexity of GraphQL schemas, facilitating the implementation of advanced features without compromising code clarity and maintainability.
