Overview of this book

Packed with practical advice and detailed recipes, this updated second edition of Angular Projects will teach you everything you need to know to build efficient and optimized web applications using Angular. Among the things you’ll learn in this book are the essential features of the framework, which you’ll master by creating ten different real-world web applications. Each application will demonstrate how to integrate Angular with a different library and tool. As you advance, you’ll familiarize yourself with implementing popular technologies, such as Angular Router, Scully, Electron, Angular service worker, Nx monorepo tools, NgRx, and more while building an issue tracking system. You’ll also work on a PWA weather application, a mobile photo geotagging application, a component UI library, and many other exciting projects. In the later chapters, you’ll get to grips with customizing Angular CLI commands using schematics. By the end of this book, you will have the skills you need to be able to build Angular apps using a variety of different technologies according to your or your client’s needs.

Creating an HTTP service

For our schematics library, we will create a schematic that scaffolds an Angular service. It will generate a service that imports the built-in HTTP client. It will also contain one method for each HTTP request that is involved in a CRUD operation.

The generation schematic that we are going to build will not stand on its own. Instead, we will combine it with the existing generation schematic of the Angular CLI for services. Thus, we do not need a separate JSON schema.

Let's get started by creating the schematic:

  1. Execute the following command to add a new schematic to our collection:
    schematics blank crud-service
  2. Open the collection.json file and provide an explanatory description for the schematic:
    "crud-service": {
      "description": "Generate a CRUD HTTP service",
      "factory": "./crud-service/index#crudService"
  3. Create a folder named files inside the crud-service...
