We’ll implement the backend that will serve the config for the gold mining game.
Our backend will be built on Express.js, so let’s install it with npm install --save express first.

Take a look at the files you have. We’ll be adding our routes to the server constant in server.js later.
For now, let’s create one more file functions.js and export the function startServer(port, server)
The function startServer(port, server) should call the server.listen(port, callback) to start a server
You can include anything you like in the callback, i.e. console.log('Server is running on port' + port)
