A Node.js middleware that adds webpack hot module replacement (HMR) to your own HTTP server, working alongside webpack-dev-middleware without needing webpack-dev-server. It handles the browser-client connection and update subscription, while applying changes via webpack's HMR API.

Use cases

• add hot reloading to an existing express server
• use webpack HMR without webpack-dev-server
• custom dev server with live module replacement
• hot reload a node backend serving a webpack bundle
• wire HMR into a framework-agnostic server setup

When to choose

• you already run your own server and want webpack hot reloading attached as middleware
• webpack-dev-server is too opinionated for your setup
• you need fine control over the dev server while keeping HMR

When to avoid

• you are happy with webpack-dev-server's built-in HMR
• your app does not use webpack
• you need the library to make your components themselves hot-reloadable (it only wires the update mechanism)
