Webpack

We will need Webpack to compile and bundle the server-side code using Babel, and for configuration we can use the same webpack.config.server.js discussed in Chapter 2, Preparing the Development Environment.

From the command line, run the following command to install webpack, webpack-cli, and the webpack-node-externals module:

npm install --save-dev webpack webpack-cli webpack-node-externals

This will install the Webpack modules and update the package.json file.
