A quick guided tour on NgRx Signal Store, and the concept of Deep Signals, timestamps in the description 😊 No music after the intro, a shorter form video. Let me know if you enjoy these more, or prefer a lix of long and short format. Enjoy everyone!👍

Thanks for giving so much to the Angular community Vasco

Wow this is moving at some pace, it was only a few weeks ago we were discussing this requirement. I'm blown away with Angular it's just superb ❤

This is like attaching individual reducers to store in REDUX, but here we are attaching pure objets that are converted to signals automatically. Really mind blowing. So there is no need to do normalization.

I do appreciate the dark theme in IDE, the lesson is more enjoyable to watch in this format

Can you do a video on how to test SignalStores? And how to mock them when testing components that use SignalStores? Or can you provide some resources?

Awesome content, Vasco. Angular developers are in good hands. Greetings from 39.6250° N, 19.9223° E

If you inject a store at a component level, it can be passed down to its children, so you don't need to inject it at the root level. At the same time, when the component is destroyed, the store will also be destroyed. In that way, the store will be bound to a page that is associated with it and will be activated only when we need it making the app faster.

Thanks a lot for the video! One quick question:
Is there a browser extension to see the actual state? For the NGRX store I always used Redux extension to see in the browser the store (and it's very helpful to debug), is there something like that for this signal store?

[JohanVrolix]

Hi Vasco, just a question: if you reach out to a real backend you would use services that use httpclient, thus returning observables which, I assume, would be turned into signals using toSignal from the Angular RxJS interop package. Would you use toSignal in the service class already or inside the SignalStore?

Hola! Excelente video. Y si quiero que el store persista a nivel de memoria? Ejemplo que no quiero que a cada rato se este invocando el get todos del service (imaginando que es un llamado a un API) ya que previamente en otro componente ya lo había cargado? Como sería esto?

[haroldpepete]

i don't like that mixture of the store using services that make request, store just need to listen for changes and modify, i preffer effects

I know the logo is physically centered but idk why it bugs me until they are visually centered 😅

What's the point w/o fine grained reactvity? Is auth.foo.bar() really that different from auth().foo.bar?
