Serving the HTML page in the Express app

We'll serve our HTML page in the Express app using a piece of Express middleware. Middleware lets us configure how our Express application works, and it's something we'll use extensively throughout the book. For now, we can think of it kind of like a third-party add-on.

In order to add some middleware, we'll call app.use. The app.use takes the middleware function we want to use. In our case, we'll use a built-in piece of middleware. So inside server.js, next to the variable app statement, we'll provide the function off of the express object:

const express = require('express');var app = express();app.use();
