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.

A better Hello World

With an understanding of Angular basics and the CLI, let us go through an app building experience. We will build a basic project and then see how it gets enhanced as we add more components and some routing to the application. The completed code for this project is available for download under Chapter 9, Angular in a Nutshell. Here's the set of commands that will set up a hello-ng-dashboard project with our components:

ng new hello-ng-dashboard --routing
cd hello-ng-dashboard
ng generate component header
ng generate component footer
ng generate component nav
ng g c dashboard

Here, the g c argument used for dashboard component creation is the same as generate component as used for others. For each component, the CLI will create a folder by the name of the component, containing the TypeScript file along with HTML and CSS files. These components will need to be...
