React Hooks was just announced today at React Conf 2018.

You can check the official documentation
& also this dev.to article, Everything you need to know about React Hooks by Carl Vitullo
so I won’t go into it further.

I created a simple hook called react-use-localstorage, which lets you store state in Local Storage.

🚀Prerequisite

You need to use following React versions.

  • react: 16.7.0-alpha.0
  • react-dom: 16.7.0-alpha.0

It’s bleeding edge and not recommended to use in production.

You can follow along on CodeSandbox.

⚒How to use it

First, install the package, react-use-localstorage.

npm i react-use-localstorage

And use it in a “Functional Component”.

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");
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("name", e.target.value)}
/>
</label>
</div>
</div>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

🏃Working Demo

The demo shows that state is saved directly in local storage.
