feat(signal_effect with explicit deps): introduce a new "watch" func having explicit signal_deps and skipFirstCallback about angular HOT 4 CLOSED

Hi, the subject of explicit effect dependencies was already discussed here: #50916.

from angular.

I know, it's discussed in many places directly or indirectly.

But in #50916, the idea is to modify the current effect function... which I personally don't like as an approach. Let's keep effect as it is.

What I'd ideally like to discuss is the following:

• is it really true that effects can be rarely used?
• what are the official counterarguments for not introducing a watch func?

As I tried to report above, my view is that the usage of effects_untrack is just kind of hidden and highly necessary (and used a lot) for common needs.

It's just that we're still mixing signals / observables... so it's not really clear. But with only signals, I have the feeling the story would be different.

IMO effects would turn (almost) unnecessary with the addition of a watch func.

@mauriziocescon this issue essentially re-iterates what was already described in #55027. We hear you but I don't think an additional issue gets us any closer to the solution - what you are describing is well understood.

Let's centralize the discussion in #55027 which represents a real-life use-case.

Ok, my bad... just started integrating signals and I find myself using the pattern above in many places! 😂

Gonna create a wrapper for now... 😂
