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.

Integration with microservices

The IMS App, with its various components, can now be put to the test by integrating it with the actual backend services. In theory, a single developer could work on the microservice, as well as the application frontend; in practice it is often not the case. In real-world development scenarios, you may either have teams collocated and working together or they could be spread out geographically. Since the system is delivered as a whole, it's often required to run all the different parts or microservices together. For example, there could be different teams managing each of our backend microservices. A team focused on UI development using Angular may need a stable version of all the IMS microservices. A backend team owning the IMS Comments project may require a certain version of IMS Users to be available during their own development. Docker provides...
