Give your APIs a REST & Make the move to GraphQL

In a world where multiple applications and devices are calling your APIs, you end up having to create custom endpoints for different views of your data. What if you could provide fewer endpoints and let the consumer decide on which data they need? 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, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools. In this session, you will learn the basic concepts of GraphQL. You will then learn how to use GraphQL in your Java applications with Spring for GraphQL. By the end of this presentation, you will be able to write and validate queries, create your own GraphQL API and write automated tests against them.
