Building Enterprise JavaScript Applications

Final steps

Before we finish, let's also document the commands we've run into npm scripts. This will make building and serving our application easier in the future.

In the package.json, define the build step with the following scripts property:

WEB_SERVER_PORT_TEST=8200WEB_SERVER_HOST_TEST=localhost
