Learning Angular - Third Edition

By: Aristeidis Bampakos, Pablo Deeleman

Overview of this book

Angular, loved by millions of web developers around the world, continues to be one of the top JavaScript frameworks thanks to its regular updates and new features that enable fast, cross-platform, and secure frontend web development. With Angular, you can achieve high performance using the latest web techniques and extensive integration with web tools and integrated development environments (IDEs). Updated to Angular 10, this third edition of the Learning Angular book covers new features and modern web development practices to address the current frontend web development landscape. If you are new to Angular, this book will give you a comprehensive introduction to help you get you up and running in no time. You'll learn how to develop apps by harnessing the power of the Angular command-line interface (CLI), write unit tests, style your apps by following the Material Design guidelines, and finally deploy them to a hosting provider. The book is especially useful for beginners to get to grips with the bare bones of the framework needed to start developing Angular apps. By the end of this book, you’ll not only be able to create Angular applications with TypeScript from scratch but also enhance your coding skills with best practices.

Organizing components into modules

As we learned in Chapter 3, Component Interaction and Inter-Communication, Angular 10 applications are represented as a tree of components. The top main component (usually dropped somewhere in the main HTML index file) acts as a global placeholder where child components turn into hosts for other nested child components, and so on. Modern web applications based on web component architectures often conform to this sort of tree hierarchy.

There are distinct advantages to this approach. On the one hand, reusability does not get compromised, and we can reuse components throughout the component tree with little effort. Secondly, the resulting granularity reduces the burden required for envisioning, designing, and maintaining larger applications. We can simply focus on a single piece of UI and then wrap its functionality around new layers of abstraction until we wrap up a full-blown application from the ground up.

Alternatively, we can approach our...
