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.

How does the compiler know which files to collect for the build process? Well, it reads the files property of the tsconfig.app.json file that indicates the main entry point of an Angular 10 app:

"files": [
  "src/main.ts",
  "src/polyfills.ts"
]

From there, it can go through all components, services, and other Angular artifacts that are needed by our application, as we have already learned in Chapter 1, Building Your First Angular App. The Angular compiler outputs the resulting JavaScript files into a folder named according...
