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.

Limiting the application bundle size

As developers, we always want to build impressive applications that contain cool features for the end user. As such, we end up adding more and more features to our Angular app – sometimes according to the specifications and at other times to provide additional value to users. However, adding new functionality in an Angular app will cause it to grow in size, which may not be acceptable at some point. To overcome this problem, we can use Angular CLI budgets for our production build.

Budgets are thresholds that we can define in the angular.json configuration file and make sure that the size of our application does not exceed those thresholds. To set budgets, we can use the budgets property of the production configuration in the build environment:

"budgets": [
  {
    "type": "initial",
    "maximumWarning": "2mb",
 &...
