First you have to install the React project. You should use create-react-app command to create a new React project.

The below code is an example of a React. You have to import "react-cookie" and use hooks like useCookies for an intuitive to use cookies in react js.

App.js

import React from "react";
import { useCookies } from "react-cookie";

const ReactCookieExample = () => {
  const [cookies, setCookie, removeCookie] = useCookies(["username"]);

  // Set a cookie
  const setCookieHandler = () => {
    setCookie("username", "JohnDoe", { path: "/" });
  };

  // Get a cookie
  const getCookieHandler = () => {
    console.log(cookies.username); // Access the cookie
  };

  // Delete a cookie
  const removeCookieHandler = () => {
    removeCookie("username");
  };

  return (
    <div>
      <button onClick={setCookieHandler}>Set Cookie</button>
      <button onClick={getCookieHandler}>Get Cookie</button>
      <button onClick={removeCookieHandler}>Delete Cookie</button>
    </div>
  );
};

export default ReactCookieExample;
