Summary
In summary, web technologies have evolved to a point where it is possible to create rich, fast, and native web applications that can run well on the vast majority of desktop and mobile browsers deployed today. Angular has become a mature and stable platform, applying lessons learned from the past. It enables sophisticated development methodologies that enable developers to create maintainable, interactive, and fast applications using technologies like TypeScript, RxJS, and NgRx-enabled patterns from object-oriented programming, reactive programming, the Flux pattern, and standalone components, along with the NgRx component store.
Angular is meant to be consumed in an evergreen manner, so it is a great idea always to keep your Angular up to date. Visit https://AngularForEnterprise.com for the latest updates and news.
Angular is engineered to be reactive through and through; therefore, you must adjust your programming style to fit this pattern. With signals, Angular even gains fine-grained reactivity. However, presentation layer reactivity is not the same as reactive programming. When signal-based components arrive circa Angular 19, Angular will no longer require reactive programming to achieve a reactive presentation layer. In Chapter 9, Recipes – Master/Detail, Data Tables, and NgRx, I provide an example of a nearly observable and subscription-free application using signals and NgRx SignalStore to show what’s possible with Angular 17. Until then, the official documentation should be your bible, found at https://angular.dev.
In the next chapter, we will review the LocalCast Weather app as a standalone app; you will learn about capturing user input with reactive forms, keeping components decoupled, enabling data exchange between them using BehaviorSubject and how the NgRx component store and Angular signals differ from these concepts. In the following chapters, you will learn about advanced architectural patterns to create scalable applications and how your Angular frontend works within the context of a full-stack TypeScript application using minimal MEAN. The book wraps up by introducing you to DevOps and continuous integration techniques to publish your apps.
