  • As developers we understand that simple concepts such as “a REST call that takes a user ID and returns the user’s JSON” is actually a carefully tuned series of filters, service calls, and transformations which make that a reality. With the growing popularity of asynchronous programming, the code to do all of that can get real ugly real fast. Java 8 introduced the CompletableFuture class which provides an elegant way to define large operations as a pipeline of smaller, more focused operations. We’ll review some core “functional programming” ideas to warm up and then build a small REST API that highlights how we can use the new futures to write cleaner, modular, elegant code.
