react-use-localstorage v3.5.3

react-use-localstorage

depends on stable v16.8.1~

Access Local Storage using React hooks.

Fork it on CodeSandbox

How to use it

import React from 'react';
import ReactDOM from 'react-dom';
import useLocalStorage from 'react-use-localstorage';

import './styles.css';

function App() {
  const [item, setItem] = useLocalStorage('name', 'Initial Value');

  return (
    <div className="App">
      <h1>Set Name to store in Local Storage</h1>
      <div>
        <label>
          Name:{' '}
          <input
            type="text"
            placeholder="Enter your name"
            value={item}
            onChange={(e) => setItem(e.target.value)}
          />
        </label>
      </div>
    </div>
  );
}

const rootElement = document.getElementById('root');
ReactDOM.render(<App />, rootElement);

Note for SSR (server-side rendering)

If you are using Gatsby or other SSR frameworks, such as Next.js, refer to this workaround by @hencatsmith.

You need to make sure that window is available.

const useSsrLocalStorage = (
  key: string,
  initial: string
): [string, React.Dispatch<string>] => {
  return typeof window === 'undefined'
    ? [initial, (value: string) => undefined]
    : useLocalStorage(key, initial);
};
