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.

Limiting the application bundle size

As developers, we always want to build impressive applications with cool features for the end user. As such, we end up adding more and more features to our Angular application – sometimes according to the specifications and at other times to provide additional value to users. However, adding new functionality to an Angular application 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.

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 command:

"budgets": [
    "type": "initial",
    "maximumWarning": "500kb",
    "maximumError": "1mb...
