atomWithToggleAndStorage

atomWithToggleAndStorage is like atomWithToggle but also persist the state anytime it changes in given storage using atomWithStorage.

Here is the source:

import { WritableAtom, atom } from 'jotai'
import { atomWithStorage } from 'jotai/utils'

export function atomWithToggleAndStorage(
  key: string,
  initialValue?: boolean,
  storage?: any,
): WritableAtom<boolean, [boolean?], void> {
  const anAtom = atomWithStorage(key, initialValue, storage)
  const derivedAtom = atom(
    (get) => get(anAtom),
    (get, set, nextValue?: boolean) => {
      const update = nextValue ?? !get(anAtom)
      void set(anAtom, update)
    },
  )

  return derivedAtom as WritableAtom<boolean, [boolean?], void>
}

And how it’s used:

import { atomWithToggleAndStorage } from 'XXX'

// will have an initial value set to false & get stored in localStorage under the key "isActive"
const isActiveAtom = atomWithToggleAndStorage('isActive')

The usage in a component is also the same as atomWithToggle.
