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.

  • Minification: Converts multiline source files into a single line by removing whitespaces and comments. It is a process that enables browsers to parse them faster later on.
  • Uglification: Renames properties and methods to a non-human-readable form so that they are difficult to understand and used for malicious purposes.
  • Bundling: Concatenates all source files of the application into a single file, called the bundle.
  • Tree-shaking: Removes unused files and Angular artifacts such as components and modules, resulting in a smaller bundle.

As we can see, the Angular CLI does a tremendous job for us as far as build optimization is concerned. However...
