Webinar: Web-Apps mit Angular: State im Griff mit NgRx Entity Adapter & Component Store

Die Konfigurierbarkeit unserer Angular-Module ist für den Aufbau einer wiederverwendbaren Architektur unerlässlich. Aber in der jüngsten Vergangenheit hat uns Angular seine neue modullose Zukunft präsentiert. Wie sieht das Ganze jetzt aus? Wie konfigurieren wir jetzt unsere Lazy-Komponenten? Lasst uns gemeinsam einen Blick darauf werfen.

As someone who enjoys the ComponentStore on an average level, I have written simple reactive CRUD logic several times. While storing a vast number of entities in the component state might not be a frequent use case, I will briefly illustrate the usage of the EntityAdapter with the @ngrx/component-store.

After introducing the @ngrx/entity package, I am often asked how to manage multiple entity types in the same feature state. While I hope that the previous part of this article series has made this more apparent, I will further focus on this question in the following.

This three-part series of blogposts is targeted at developers who have already gained experience with NgRx but still manage their collections themselves. In the first part I introduce the Entity Adapter, in the second part I show you how to connect it to NgRx and in the third part how to do it with the Component Store as well.

In this article, we will explore how to apply the concept of smart and presentational components with Angular. We will choose a complex-enough target to see all aspects in action, yet understandable and within the scope of this article. The goal is to teach you how to use this architecture in your way. For that, we will iterate through different development stages, starting with the target selection and implementing it in a naive way. After the first development, we will refactor that naive solution into smart and presentational components that are reusable, refactor-friendly, and testable.

When optimizing the performance of Angular applications, many developers directly associate Angular's OnPush change detection strategy with it. But, if you don't know exactly how OnPush works under the hood, it will quickly teach you what you are doing wrong the hard way. In this article, we'll look deeper into how the OnPush strategy affects Angular's change detection mechanism and which pitfalls we should avoid at all costs.
