Hot Module replacement is not working ! Chapter 1

[rocktimsaikia]

I'm currently in chapter 1(page 17) of the book where i got introduced to Hot Module Replacement which seems like a very useful tool in development stage but when i tried to apply it in my hackernews app it does not reload the page automatically on changes.What could be the problem here ?

    import React from 'react';
    import ReactDOM from 'react-dom';
    import './index.css';
    import App from './App';
    
    ReactDOM.render(, document.getElementById('root'));
    
    if (module.hot) {
    module.hot.accept();
    };

You aren't rendering your 'App'.

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