What is react-refresh?
The react-refresh package is used to enable fast refresh capabilities in React applications. Fast Refresh is a feature that allows you to get instant feedback for changes in your React components. With Fast Refresh enabled, most edits should be visible within a second, without losing component state. This leads to a more productive development experience by allowing developers to see changes almost instantly.
Hot Reloading
This code enables hot reloading for a React component. When changes are made to the 'App' component, it will be reloaded without refreshing the entire page, preserving the application state.
if (module.hot) {
module.hot.accept('./App', () => {
const NextApp = require('./App').default;
ReactDOM.render(<NextApp />, document.getElementById('root'));
});
}
