Overview of this book

Essential Angular is a concise, complete overview of the key aspects of Angular, written by two Angular core contributors. The book covers the framework's mental model, its API, and the design principles behind it. This book is fully up to date with the latest release of Angular. Essential Angular gives you a strong foundation in the core Angular technology. It will help you put all the concepts into the right places so you will have a good understanding of why the framework is the way it is. Read this book after you have toyed around with the framework, but before you embark on writing your first serious Angular application. This book covers concepts such as the differences between Just-In-Time (JIT) and Ahead-Of-Time (AOT) compilation in Angular, alongside NgModules, components and directives. It also goes into detail on Dependency Injection and Change Detection: essential skills for Angular developers to master. The book finishes with a look at testing, and how to integrate different testing methodologies in your Angular code.

Web applications heavily rely on forms. In many ways Angular is so successful because two-way bindings and ng-model made creating dynamic forms easy.

Although very flexible, the AngularJS 1.x approach has some issues: the data flow in complex user interactions is hard to understand and debug.

Angular 2+ builds up on the ideas from AngularJS 1.x: it preserves the ease of creating dynamic forms, but avoids the issues making data flow hard to understand.

In this chapter we will look at how form handling (or input handling) works in Angular.
