Overview of this book

The Angular framework, powered by Google, is the framework of choice for many web development projects built across varying scales. It’s known to provide much-needed stability and a rich tooling ecosystem for building production-ready web and mobile apps. This recipe-based guide enables you to learn Angular concepts in depth using a step-by-step approach. You’ll explore a wide range of recipes across key tasks in web development that will help you build high-performance apps. The book starts by taking you through core Angular concepts such as Angular components, directives, and services to get you ready for building frontend web apps. You’ll develop web components with Angular and go on to cover advanced concepts such as dynamic components loading and state management with NgRx for achieving real-time performance. Later chapters will focus on recipes for effectively testing your Angular apps to make them fail-safe, before progressing to techniques for optimizing your app’s performance. Finally, you’ll create Progressive Web Apps (PWA) with Angular to provide an intuitive experience for users. By the end of this Angular book, you’ll be able to create full-fledged, professional-looking Angular apps and have the skills you need for frontend development, which are crucial for an enterprise Angular developer.

Converting an existing Angular app into a PWA with the Angular CLI

A PWA involves a few interesting components, two of which are the service worker and the web manifest file. The service worker helps to cache the static resources and caching requests, and the web manifest file contains information about app icons, the theme color of the app, and so on. In this recipe, we'll convert an existing Angular application to a PWA. The principles apply to a fresh Angular app as well if you were to create it from scratch. For the sake of the recipe, we're going to convert an existing Angular app. We'll see what changed in our Angular web app and how the @angular/pwa package converts it into a PWA. Also, how it helps to cache the static resources.
