Description
I find myself in a situation often where a component needs to build up some derived state from a series of different atoms/selectors—this may even be looping over an array of atoms/selectors. And to do that I'm forced to create a new selector that represents this components derived state (to have access to get in a context where looping is fine).
Instead, it would be nice if there was a useRecoilMemo which was similar to useMemo except it received ({ get }) as a parameter. So you could do complex aggregations right inline without having to define these one-off atoms/selectors.
Here's a very simplified example:
const Component = ({ users }) => {
const data = useRecoilMemo(({ get }) => {
return users.map(user => get(userProfileSelectorFamily(user.id)))
}, [users])
return <div>{data...}</div>
}
But these aggregations are often much more complex.
