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.

Passing parameters to routes

A common scenario in enterprise web applications is to have a list of items, and when you click on one of them, the page changes the current view and displays details of the selected item. The previous approach resembles a master-detail browsing functionality, where each generated URL on the master page contains the identifiers required to load each item on the detail page.

We can represent the previous scenario with two routes navigating to different components. One component is the list of items, and the other is the details of an item. So, we need to find a way to create and pass dynamic item-specific data from one route to the other.

We are tackling double trouble here: creating URLs with dynamic parameters at runtime and parsing the value of these parameters. No problem: the Angular router has our back, and we will see how with a real example.
