What is react-hot-loader?

react-hot-loader is a tool that allows React components to be live reloaded without losing their state. This is particularly useful during development as it speeds up the feedback loop by allowing developers to see changes in real-time without refreshing the entire application.

What are react-hot-loader's main functionalities?

Hot Module Replacement

This feature allows you to wrap your root component with the `hot` function from react-hot-loader. This enables Hot Module Replacement (HMR) for the component, meaning that changes to the component will be applied in real-time without a full reload.

import { hot } from 'react-hot-loader/root';
import App from './App';

const HotApp = hot(App);

export default HotApp;

Preserve Component State

By using react-hot-loader, the state of your React components is preserved even when the component code is updated. This is particularly useful for maintaining the current state of your application during development.

import { hot } from 'react-hot-loader/root';
import App from './App';

const HotApp = hot(App);

export default HotApp;

Error Handling

react-hot-loader provides better error handling during development. When an error occurs, it does not break the entire application but instead shows the error in the console, allowing you to fix it without losing the application state.

import { hot } from 'react-hot-loader/root';
import App from './App';

const HotApp = hot(App);

export default HotApp;
