In this video we switch from the server side to the client side. We build a standalone Spring Boot application that calls our GraphQL API using Spring's built-in HttpSyncGraphQlClient. We walk through the whole process from constructing the client with a RestClient, defining your query as a document, passing in variables and deserializing the response directly into your entity classes. If you've ever needed to consume a GraphQL API from Java this is how you do it with Spring.
