Utility for bundling selectors

[kentkwee]

Current Situation

I often find myself bundling selectors especially for view selectors.
If I don't need to process the data in the selector this could look like the following:

const selectViewModel = createSelector(
  selectA,
  selectB,
  selectC,
  (valueA, valueB, valueC) => ({ valueA, valueB, valueC })
);

Adding and removing selectors would require me to modify 3 places in the code.

Proposal

I created a utility function to simplify this process

type SelectorResult<S> = S extends Selector<never, infer Result>
  ? Result
  : never;

type SelectorMapResult<SelectorMap> = {
  [K in keyof SelectorMap]: SelectorResult<SelectorMap[K]>;
} & unknown;

function createSelectorBundle<
  State,
  SelectorMap extends Record<PropertyKey, Selector<State, unknown>>
>(obj: SelectorMap): MemoizedSelector<State, SelectorMapResult<SelectorMap>> {
  const keys = Object.keys(obj);
  const selectors = Object.values(obj);
  const projector = (...args: unknown[]): any =>
    Object.fromEntries(keys.map((key, i) => [key, args[i]]));
  return createSelector(...selectors, projector);
}

which would allow me to write this instead:

const selectViewModel = createSelectorBundle({
  valueA: selectA,
  valueB: selectB,
  valueC: selectC
});

Do you have any suggestions for improvement?
What do you think? Would it be suitable to be included into the core library?
