observer-spy VS platform

Observer-Spy is from Shai Reznik and is indispensable when testing observables. It takes so much of the boilerplate and scariness out of testing. auto-spies is another library from Shai. This library will create spies for you from your objects. ng-mocks has become a must-have in my testing toolkit. It allows some amazing things to happen. For example, imports: [MockModule(MyModuleDependency)]. It makes testing so easy and often painless.

NgRx is the standard library for state management in Angular applications. With NgRx v14, many of the complex APIs following the Redux pattern have been greatly simplified. For example, ActionGroups make it easier to define new actions. However, the use of the Redux pattern is by no means easy and discourages many developers.

I ran into this question question on the NgRx GitHub discussion threads which asked:

In an application that I’m working on, before Angular 16 shipped, I was using a custom StoreService to hold global application state. I’ve tried libraries like NgRx and Akita to manage global state, but found them to be way too heavy-handed for what I wanted (not saying ANYTHING negative towards these libraries; not every tool is right for every job, and the authors of these libraries would probably be the first to tell you that). This custom StoreService was created using RxJS, and looked like this:

The store can be implemented using any technology. You can either use a library like NgRx or NGXS. Another solution is to create your own store using a BehaviorSubject.

I'm using @ngrx/router-store in my Angularv5 app and I recently started running into a an error: Navigation ID X is not equal to the current navigation id Y (where X and Y are integers).

Not agree, NgRx and redux pattern helps a lot to keep the code clean, I do agree that maybe NgRx add many files and could become in boilperplate for simple staff, I think with signals this approach will change, there is already an open discussion about this https://github.com/ngrx/platform/discussions/3796

For code sample and how to architect these things : https://ngrx.io

The NgRx team and Marko Stanimirović opened a new RFC (Request for Comments) for a signal-based state management solution, SignalStore. It has a similar approach to @ngrx/component-store. The initial prototype with the API documentation is available in the NgRx SignalStore playground repo.
