Here’s a live example in TS Playground GraphQL Union and TypeScript Union Type GraphQL is a query language that is used to define the API of a server. Like TypeScript GraphQL queries can traverse related objects and their fields, letting clients fetch lots of related data in one request, instead of making several roundtrips as one would need in a classic Additionally, you can access the fields on any implementing type using GraphQL fragments, as long as you specify the type. These types let a single field return values of different object types, while keeping your schema type-safe. In this article, we will go through the use cases for abstract types and how we can implement them in Here, the searchMedia field returns [MediaItem!], a list where each member is part of the MediaItem union. Mutations make modifications to data and return a result. The Result union enables Query. With GraphQL, we can maintain a Schema that defines what data we can query from the server, and we can define a proper Additionally, you can access the fields on any implementing type using GraphQL fragments, as long as you specify the type. Product Build APIs Public API Hub API Hub for Enterprise Rapid API Client VSCode Doing More With GraphQL: Interfaces and Unions Learn how to use GraphQL's interface and union types GraphQL’s type system is the distinguishing feature in comparison to other protocols like REST, Falcor, and JSON Schema. NETMutations To perform a mutation you need to have a root Mutation object that is an ObjectGraphType.

Let’s examine an example of a GraphQL query that uses the In the GraphQL specification, we are able to use two abstract types - interfaces and unions. So, for each member, we want to select different fields depending on which This guide provided an overview of using interfaces and unions in GraphQL schemas. GraphQL introspection serves as a powerful platform for GraphQL includes two kinds of abstract types: interfaces and unions. As a result, when we query a field that returns a union type, we have to be more specific about the fields we want and which of the object types they can be found on.
