## What it is
A Webpack plugin that enables React Fast Refresh (hot reloading) for React components, preserving state during edits. It integrates with webpack 5 and includes an error overlay for runtime errors.

## Use cases
- enable fast refresh for react components in webpack
- hot reload react app without losing state
- add hot module replacement for react to webpack config
- show error overlay during react development
- set up react fast refresh in a custom webpack setup

## When to choose
- you use webpack 5 and want state-preserving hot reloads for React
- you maintain a custom webpack config instead of a framework CLI
- you need an error overlay during React development

## When to avoid
- you use Vite, Next.js, or CRA which bundle fast refresh already
- your project uses webpack 4 or older React versions
- you need production builds only

- function: build-tool, developer-tools
- domain: frontend, web-development, developer-tools
