Webpack Dev Server

The 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 Sock.js.

The server emits information about the compilation state to the client, which reacts to those events. You can choose between different modes, depending on your needs.

var path = require("path");
module.exports = {
  entry: {
    app: ["./app/main.js"]

    filename: "bundle.js"
  }
};
