React Hot Loader is a development tool for React applications that enables hot module replacement (HMR). It allows you to make changes to your React components and see the updates instantly without having to manually refresh the page. This greatly improves the development workflow and speeds up the iteration process.
Compared to the default React development experience, React Hot Loader provides a more seamless and efficient way to update your components in real-time. It preserves the application state during hot updates, which means you don't lose your current state when making changes. React Hot Loader also supports error handling and provides helpful error messages to aid in debugging.
However, it's important to note that React Hot Loader is marked as deprecated and is no longer actively maintained. It is recommended to use other alternatives like React Refresh or Fast Refresh, which are officially supported by the React team and offer similar functionality.
