Questions tagged [webpack-dev-server]

a Node.js based server that supports live reloading and is used for development of webpack powered applications.

webpack-dev-server is a little Node.js Express server, which uses the webpack-dev-middleware to serve a webpack bundle. It also has a little runtime which is connected to the server via Socket.IO. The server emits information about the compilation state to the client, which reacts to those events by updating the bundle.

The server is used for development purpose only.
