atomWithReset

Ref: https://github.com/pmndrs/jotai/issues/41

function atomWithReset<Value>(
  initialValue: Value
): WritableAtom<Value, SetStateAction<Value> | typeof RESET>

Creates an atom that could be reset to its initialValue with useResetAtom hook. It works exactly the same way as primitive atom would, but you are also able to set it to a special value RESET. See examples in Resettable atoms.

Example

import { atomWithReset } from 'jotai/utils'


const dollarsAtom = atomWithReset(0)
const todoListAtom = atomWithReset([{ description: 'Add a todo', checked: false }])
