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.

Optimizing the application bundle

As we learned in the Building an Angular application section, the Angular CLI performs optimization techniques when we build an Angular application. The optimization process that is performed in the application code includes modern web techniques and tools, including the following:

  • Minification: Converts multiline source files into a single line 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 services, resulting in a smaller bundle.
  • Font optimization: Inlines external font files in the main HTML file of the application...
