GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API.

In this course, we will learn about GraphQL and how we can use it to create truly decoupled client and server. Writing backend with GraphQL makes our code more declarative wherein the client demands certain data in a particular format and the server responds in a predictable manner. This enables us to evolve our API without versions and iterate on features faster. For front-end and networking, we will use Facebook’s React and Relay respectively. We will learn GraphQL by creating a backend for a blog platform. You will learn about GraphQL schema design, authentication, pagination, testing, query batching and more and how to connect a GraphQL backend to React and Relay client. The course will teach everything to get up and running with GraphQL and React.
