I really like your videos, but please use Dark Mode 😅

You were the first on YouTube to explain this new feature 🎉, thank you!

Played around with signals for a bit, there are 2 issues with them:
1. Storing a signal in a variable and then accessing it in the template will cause a signal to lose its reactivity. In my case I used a signal from one service in a second service. When it was updated in the first service, the second one didnt know about it.
2. Signals dont work with objects, again no reactivity if one of the properties change. So far it's good for primitives only.

Id like to see how you solve an array containing multiple signals.
Where you could append or pop signals in the array, together with a trackBy in the template.

This would mean that we first off have a template that only emits changes to the changed signal due to trackBy, but also only reacts on the signal change of that specific iteration in the array.

Meaning that we only emit one event in a list of array, without computing the rest of the unchanged entries in the array?

please produce a video on how to embed signals inside an HTML template which now fixes the problem of not needing to embed methods which were an anti-pattern.

I'm planning to move away from ngrx (global) state management to signals. One reason is because of the boilerplate needed to setup ngrx(actions, effects and reducers). What are your thoughts on this? Do you think this is ok?

It’s looks like the pattern with service with private behaviorsubject and a public derived observable 👍🏻

Hello, I just want to ask if signals are production ready on angular 17? thanks

I don't understand why I need use signals instead of Subjects?
