FEATURE: angular effects untracked SkipInitial #56098
Description
Which @angular/* package(s) are relevant/related to the feature request?
core
Description
The effect has to do an Initial run to keep track of the used signal, If we have untracked inside of it it would be nice to skip the Initial run.
Proposed solution
constructor() {
effect(() => {
const someSignalValue = this.signalStuff()
untracked(() => {
this.doSomethingWithValue(someSignalValue)
},{skipInitial: true});
});
}Alternatives considered
constructor() {
let skipInitial = true;
effect(() => {
const someSignalValue = this.signalStuff()
untracked(() => {
if (skipInitial) {
skipInitial = false;
return;
}
this.doSomethingWithValue(someSignalValue)
});
});
}

Could you tell us more about the real-life use-case? Why would the "initial run" be any special?
ScriptType commentedon May 29, 2024
In A Custom Form Component i use signals and effect´s to call onChange. The Problem with the initial run is the component directly becomes pristine === false .

I don't get the idea, but curios to see a real example on StackBlitz.

Agree with @e-oz - it is hard to understand the real-life use-case here. We really need code example in a stackblitz - otherwise it is not actionable for us.

I'm going to close this one since we didn't get more concrete info besides
In this case the effect could skip processing under specific conditions. Again, hard to say more given the available information.
