Overview of this book

The demand for modern and high performing web enterprise applications is growing rapidly. No more is a basic HTML frontend enough to meet customer demands. This book will be your one-stop guide to build outstanding enterprise web applications with Java EE and Angular. It will teach you how to harness the power of Java EE to build sturdy backends while applying Angular on the frontend. Your journey to building modern web enterprise applications starts here! The book starts with a brief introduction to the fundamentals of Java EE and all the new APIs offered in the latest release. Armed with the knowledge of Java EE 8, you will go over what it's like to build an end-to-end application, configure database connection for JPA, and build scalable microservices using RESTful APIs running in Docker containers. Taking advantage of the Payara Micro capabilities, you will build an Issue Management System, which will have various features exposed as services using the Java EE backend. With a detailed coverage of Angular fundamentals, the book will expand the Issue Management System by building a modern single page application frontend. Moving forward, you will learn to fit both the pieces together, that is, the frontend Angular application with the backend Java EE microservices. As each unit in a microservice promotes high cohesion, you will learn different ways in which independent units can be tested efficiently. Finishing off with concepts on securing your enterprise applications, this book is a handson guide for building modern web applications.

Summary

REST APIs are the standard for building web services that publish business capabilities. The Java EE 8 release has enhanced the underlying JAXRS specification to version 2.1, and has brought in additions that help programmers efficiently work with the APIs. The enhancements are not restricted to server-side, but there are changes such as reactive-style programming for Client APIs. Integration with CDI and Bean Validation APIs have made declarative programming a breeze. The validation of API input and output, along with container-based dependency injection of resources and support for JSON, makes this a powerful model to use for microservices.

While standards aid in building services, external tools such as Swagger fill the gap of documentation support. SSE, as part of JAXRS, along with WebSockets, bring in different capabilities that can be leveraged when building solutions...
