Moving Beyond REST - GraphQL and Java & Spring

Explore GraphQL as an alternative or complement to REST-based API development in this conference talk from Spring I/O 2019. Learn the basics of GraphQL and discover how to create a GraphQL server and consume it in a Java client. Understand the advantages of GraphQL, including faster and more flexible development, and see how to easily integrate it into an existing Spring Boot application. Dive into topics such as GraphQL schemas, endpoints, query parameters, and libraries. Witness practical demonstrations and gain insights into best practices, antipatterns, and the benefits of using GraphQL with Spring. Examine real-world examples, including how to handle authentication, authorization, and mutations in GraphQL applications.
