Here was a first attempt at the code, but it didn't really make sense.
Issue 1: A variable is needed that gets the current context the signal is in. This is probably getActiveConsumer()
. I don't know if this is available in Angular 16.
Issue 2: how are multiple calls distinguished? An anonymous function would be the best, but it would be hard to distinguish from a signal, and what if somebody tries to reuse the same one more than once for some reason?
export function nestedSignal<V extends (...args: never[]) => Signal<unknown>>(fn: V, ...params: Parameters<V>): () => ReturnType<V> {
let isReady = false;
let source: ReturnType<V>;
return () => {
if (isReady) {
return source;
}
source = fn.apply(fn, params) as ReturnType<V>;
isReady = true;
return source;
};
}
