Type Union

Description: A union type in GraphQL allows a field to return multiple types, providing greater flexibility in the structure of queries. Unlike standard object types, which return a single data type, unions enable a field to resolve to different object types, facilitating the representation of heterogeneous data. This is particularly useful in situations where a field may contain different types of data, such as in an API that handles multiple related resources. Unions are defined in the GraphQL schema and are used alongside queries to specify which types can be returned. By implementing a union type, developers can create more dynamic and adaptable APIs, enhancing the user experience by allowing applications to efficiently handle varying types of responses.
