Conditional fetch without atom

[ice-cap0]

hey !

this

const buildPostQuery =
  ({ id }: { id?: string }) =>
  () =>
    createFetcherStore<PostType>(id ? `posts.get?id=${id}` : [])

still fires!

from the docs:

if any atom value is either NoKey, we never call the fetcher—this is the conditional fetching technique we have;

is it really only atoms in key list that can prevent fetch (when NoKey)? can you not have any of the raw NoKey values

type NoKey = null | undefined | void | false;

to prevent fetch?

fwiw an enabled option would be awesome!

I've encountered a need for raw NoKey values on the key list as well! It would be great to have when building local fetcher stores like this:

const createStore = (id: string | null) => () =>
  createFetcherStore<{ avatarUrl: string }>([`/api/user/`, id]);

const UserAvatar: FC<{ id: string | null }> = ({ id }) => {
  const [$user] = useState(createStore(id));

  const { data } = useStore($user);
  if (!data) return null;

  return <img src={data.avatarUrl} />;
};
