Understanding the GraphQL Type System
GraphQL is a modern solution for facilitating the communication between a front end and a data source. In order to write a functioning GraphQL schema, you must understand the GraphQL Type System. In this article, you will learn about the five built-in scalar types, Enums, Object types (and the abstract types that work alongside them), and the List and Non-Null wrapping types. You will see examples for each type and learn how to use them to build a complete GraphQL schema.
