Safe implementations for localStorage and sessionStorage, which fallbacks to in-memory implementation if default browser implementations aren't available. For example, when in private mode in Safari, storages are available, but an attempt to write to them throws an error.
npm i -S safe-storage
safe-storage has the same signature as localStorage and sessionStorage, so you can use it as you would use normal localStorage or sessionStorage. Example:
import { safeLocalStorage } from 'safe-storage';
safeLocalStorage.setItem('token', '<123456789>');
console.log(safeLocalStorage.getItem('token'));
// output: <123456789>
console.log(safeLocalStorage.length);
// output: 1
safeLocalStorage.removeItem('token');
console.log(safeLocalStorage.getItem('token'));
// output: nullFor sessionStorage:
import { safeSessionStorage } from 'safe-storage';
