How to Use Enumeration Types
Thus, we can create an enumeration type in GraphQL by enumerating all the possibilities we wish to permit for a given field. For instance, we may see choices like To Do, In Progress, or Done for a task’s state. Once the “enum” keyword has been used, we place these options inside curly braces.
Here’s how we set up an enumeration type in GraphQL:
enum TaskStatus {
TODO
IN_PROGRESS
DONE
}
Explanation: We can list out all the options we want to allow for a field, like the status of a task, inside curly braces after using the “enum” keyword.
Enumeration Types in GraphQL Schema
In the area of GraphQL schema design, enumeration types play an important role in defining a structured set of values for specific fields. Enumerations serve as a means to restrict the possible options for a field, ensuring data consistency and clarity throughout an API. In this article, we will explore the concept of enumeration types in GraphQL with their importance through practical examples and use cases.
