Overview of this book

As Angular continues to reign as one of the top JavaScript frameworks, more developers are seeking out the best way to get started with this extraordinarily flexible and secure framework. Learning Angular, now in its fourth edition, will show you how you can use it to achieve cross-platform high performance with the latest web techniques, extensive integration with modern web standards, and integrated development environments (IDEs). The book is especially useful for those new to Angular and will help you to get to grips with the bare bones of the framework to start developing Angular apps. 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. Updated for Angular 15, this new edition covers lots of new features and tutorials that address the current frontend web development challenges. You’ll find a new dedicated chapter on observables and RxJS, more on error handling and debugging in Angular, and new real-life examples. 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.

Group features into modules

Each Angular module represents a particular feature of an Angular application. The way these feature modules are added to the application depends on the business needs. In this section, we will investigate three different ways:

  • Adding modules in the main application module
  • Adding modules to another feature module
  • Grouping feature modules by type

In the following sections, we will explore each way in more detail.

Add module in the main module

We have already learned how to create a new Angular module for our application using the Angular CLI. Creating an Angular module does not make it automatically available to the application. It is our responsibility to register the new module with the rest of the application using the main application module:

  1. Open the app.module.ts file and add a new import statement to import ProductsModule:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
