react-refresh

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.

What are react-refresh's main functionalities?

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'));
  });
}

Other packages similar to react-refresh

react-hot-loader

React Hot Loader is a plugin that allows React components to be live reloaded without the loss of state. It is similar to react-refresh but was more commonly used before the introduction of Fast Refresh. React Hot Loader is now considered largely obsolete in favor of react-refresh, which is more robust and has better support from the React team.

webpack-hot-middleware

Webpack Hot Middleware is a middleware for webpack that allows hot reloading of modules in development mode. It is similar to react-refresh in that it helps with live reloading of changes. However, it is more generic and not specific to React. It requires more manual setup compared to react-refresh, which is more integrated with React's development environment.
