TypeScript type WriteOnlySelectorOptions<T> ?

Hello ! 👋 I would like to know if the implementation of a WriteOnlySelectorOptions<T> is planned. I would like to use a selector to only Write and not Read values.

If this case we should have this i think :

export interface WriteOnlySelectorOptions<T> {
    set: (
        opts: {
            set: SetRecoilState;
            get: GetRecoilValue;
            reset: ResetRecoilState;
        },
        newValue: T | DefaultValue,
    ) => void;
}

---

Currently we have only this :

export interface ReadWriteSelectorOptions<T> extends ReadOnlySelectorOptions<T> {
    set: (
        opts: {
            set: SetRecoilState;
            get: GetRecoilValue;
            reset: ResetRecoilState;
        },
        newValue: T | DefaultValue,
    ) => void;
}

I get errors in the image above because i must use the get inside my selector (but for my case i don’t need it !)

Thank you ! Works like a charm !

Actually, you can also avoid useRecoilCallback() entirely:

const [currentTheme, setTheme] = useSetRecoilState(currentThemeStore);
const toggleCurrentTheme = useCallback(() => {
  const newTheme = currentTheme === 'light' ? 'dark' : 'light';
  if (newTheme === 'dark') {
      document.body.classList.remove('body-light');
      document.body.classList.add('body-dark');
      setTheme('dark');
  } else {
      document.body.classList.remove('body-dark');
      document.body.classList.add('body-light');
      setTheme('light');
    }
    // Set colorsStore according to new theme
    set(colorsStore, setColorsObject(newTheme));
    // Set CSS variables according to new theme
    setColorsVariables(newTheme);
    // Set preference into localStorage
    window.localStorage.setItem('color-mode', newTheme);
});
