Getting Started with GraphQL
In Chapter 11, we explored how to create a gRPC service in ASP.NET Core. gRPC is a high-performance RPC framework that facilitates communication between services. We discussed the field types used in protobuf messages, and how to define four types of gRPC services: unary, server streaming, client streaming, and bidirectional streaming. Additionally, we learned how to configure gRPC services in ASP.NET Core and how to call gRPC services from a client application.
Next, we will explore another shape of web APIs: GraphQL. GraphQL is a query-based API that allows clients to specify the data they need, which solves the problem of over-fetching and under-fetching data. Besides, GraphQL supports mutations, which allow clients to modify data. In this chapter, we will learn about some basic concepts of GraphQL and how to create a GraphQL API in ASP.NET Core. We will cover the following topics in this chapter:
- Recap of GraphQL
- Setting up a GraphQL...
