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

We have seen the IMS app frontend project and the general features which cover the common cases, which needs to be addressed when building angular applications. The project-introduced feature module has its own set of components. We used reactive and template-driven forms to display and capture user input. We went over the basic use of HttpClient to retrieve our mock JSON data, allowing us to work independently of the backend team.

While this is not an exhaustive application, it does lay the foundations for dealing with CRUD applications with their own complexities. The separation of domains for entities and shared services is just the beginning for structuring the project. As the project evolves, more strategies such as core modules, lazy modules, and shared modules can be employed to allow for scaling the application. In the next chapter, we will explore integrating...
