调研方向

Start at the existing useCookie hook and inspect how it reads and updates the cookie value. Compare its current return value and update behavior with the requested refresh operation. Done means an external cookie change can be read through the hook after refresh is called, with deletion still reflected in the hook state.

描述

Is your feature request related to a problem? Please describe.
My cookie is changed by a request done in some API call. I need to react to that change. The new cookie value is not by useCookie() because it assumes that all changes are done through it.

Describe the solution you'd like
A refresh would probably suffice. Something like this:

import { useCallback, useState } from 'react';
import Cookies from 'js-cookie';

const useCookie = (
  cookieName: string
): [string | null, (newValue: string, options?: Cookies.CookieAttributes) => void, () => void, () => void] => {
  const [value, setValue] = useState<string | null>(() => Cookies.get(cookieName) || null);

  const updateCookie = useCallback(
    (newValue: string, options?: Cookies.CookieAttributes) => {
      Cookies.set(cookieName, newValue, options);
      setValue(newValue);
    },
    [cookieName]
  );

  const refreshCookie = useCallback(() => {
    const newValue = Cookies.get(cookieName);
    if (newValue === value) {
      return;
    }
    if (newValue !== undefined) {
      updateCookie(newValue);
    } else {
      deleteCookie();
    }
  }, [cookieName, updateCookie, value]);

  const deleteCookie = useCallback(() => {
    Cookies.remove(cookieName);
    setValue(null);
  }, [cookieName]);

  return [value, updateCookie, deleteCookie, refreshCookie];
};

export default useCookie;

(not tested)

Usage:

const [value, update, delete, refresh] = useCookie("sessionData");
// ...
fetch("/settings/update").then(() => refresh());
