Feature request: Selector-like hook for components #2303

Open derolf opened 5 months ago

derolf commented 5 months ago

Imagine we had

const [get, getCallback] = useRecoil();

where get and getCallback have the same semantics as in the getter of selector.

Then I could write:

function Foo() {
  const [get, getCallback] = useRecoil();
  return <>{get(myAtom)} <button onClick={() => getCallback(({i}) => i.set(myAtom, 42))}>42</button></>
}

what was the motivation behind this?

The motivation is to avoid value/state-hooks for every piece the component is using.
