Description: An enum type is a special type that defines a set of possible values in GraphQL. These values are constants and are used to represent a limited set of options that a property can have. Enums are particularly useful for ensuring that the data sent and received through an API adheres to a specific set of predefined values, helping to maintain data integrity and avoid errors. By defining an enum type, a clear and concise way to specify which values are valid is provided, making it easier for both developers and consumers to understand the API schema. Additionally, enums can enhance automatically generated documentation, as the possible values are presented explicitly. In summary, enum types in GraphQL are a powerful tool for defining and restricting the values that can be used in APIs, thereby improving the robustness and clarity of API design.
