Bootiful Development with Spring Boot and Angular - RWX 2018

To simplify development and deployment, you want everything in the same artifact, so you put on your Angular app “inside” and your Spring Boot app, right? But what if you could create your Angular app as a standalone app and make cross-origin requests to your API?

This session shows how to develop with Java 11, Spring Boot, Angular 7, and TypeScript. You'll learn how to create REST endpoints with Spring MVC, Spring Data REST, configure Spring Boot to allow CORS, and create an Angular app to display its data.
