React Hot Loader is a library that lets developers tweak React components in real time, preserving component state during hot module replacement with webpack and Babel. It is now deprecated in favor of React Fast Refresh, which is built into React Native, Next.js, Create React App, and the react-refresh-webpack-plugin.
Use cases
- hot reload react components without losing state
- live edit react components during development
- preserve react state on hot module replacement
- set up hot reloading in a webpack react project
- legacy react project without fast refresh support
When to choose
- your bundler or environment does not yet support React Fast Refresh
- maintaining an older webpack-based React codebase already using it
When to avoid
- starting a new React project - use React Fast Refresh instead
- using React Native 0.61+, Next.js 9.4+, Create React App 4+, or react-refresh-webpack-plugin, all of which support Fast Refresh natively
