‘browserrouter’ is not defined react/jsx-no-undef

The error message “React/jsx-no-undef: ‘browserrouter’ is not defined” occurs when using the BrowserRouter component from React Router but forgetting to import it from the react-router-dom library.

In order to use BrowserRouter in your React application, you need to follow these steps:

1. Make sure you have installed the react-router-dom package. You can do this by running the following command in your project directory:

   npm install react-router-dom

2. Import the BrowserRouter component at the top of your file:

   import { BrowserRouter } from 'react-router-dom';

3. Use the BrowserRouter component in your JSX code, enclosing your entire application inside it. For example:

   
   import React from 'react';
   import ReactDOM from 'react-dom';
   import { BrowserRouter, Route, Link } from 'react-router-dom';
   
   const App = () => (
     <BrowserRouter>
       <div>
         <nav>
           <ul>
             <li>
               <Link to="/">Home</Link>
             </li>
             <li>
               <Link to="/about">About</Link>
             </li>
             <li>
               <Link to="/contact">Contact</Link>
             </li>
           </ul>
         </nav>
   
         <Route path="/" exact component={Home} />
         <Route path="/about" component={About} />
         <Route path="/contact" component={Contact} />
       </div>
     </BrowserRouter>
   );
   
   const Home = () => <h1>Home</h1>;
   const About = () => <h1>About</h1>;
   const Contact = () => <h1>Contact</h1>;
   
   ReactDOM.render(<App />, document.getElementById('root'));
         

By following these steps, the ‘browserrouter’ is not defined error should be resolved, and you will be able to use the BrowserRouter component in your React application.
