Hi, this behavior is expected.
You're mutating your array in your add
method with usersSignal.push('simple signal');
.
Signals check the reference by default (if you don't provide a compare function).
from angular.
For information for readers : the solution is to use update like this
// creation of 2 signals
usersSignalStore: WritableSignal<string[]> = signal(['first']);
usersCountCompute = computed(() => {
const users = this.usersSignalStore();
return users.length;
});
...
...
// update of the array
this.usersSignalStore.update((items) => [...items, 'simple signal']);
But this solution is not working for Signals created with toSignal on Observable. No solution for instance.
from angular.
