Beschreibung
I'm trying to generate a callback that is able to update an atom, I attempted to use getCallback and use the set function it provides, but it does nothing:
const tokenState = atom({
key: 'token',
default: 'no token yet',
});
const auth = selector({
key: 'auth',
get: async ({ get, getCallback }) => {
const login = getCallback(({ set }) => async () => {
console.log('logging in...');
set(tokenState, 'logged in!');
});
return {
token: get(tokenState),
login,
};
},
});
Expected behaviour:
- Either an error is thrown telling the user this is not how it works
- Or the atom is updated as one would expect
Example: https://stackblitz.com/edit/react-ts-4ezf3k?file=App.tsx
Update: Changing the get of the selector to a non async function appears to make it work as expected, any insight ?
