Understanding GraphQL Interfaces
An interface in GraphQL acts as a blueprint for a collection of fields and types, that can be reused by some other field or types in a GraphQL query. With its help, we can define some common set of interfaces, and use those in our actual schema to abstract out our business logic, and give our schema greater flexibility.
Interfaces in GraphQL Schema
GraphQL is a powerful open-source query language for APIs. It is known for its flexibility and efficiency in fetching data from server endpoints. Unlike traditional REST APIs, which often have multiple endpoints for different resources, GraphQL typically exposes a single endpoint that allows clients to request exactly the data they need.
Interfaces in GraphQL help create a common set of fields and types that can be reused by other types or Queries. In this article, we will learn about the interfaces in GraphQL Schema.
