Build a full-stack application.
Create a back-end application using express. You should have at least one model and all CRUD routes for that model.
Create a public directory with HTML, CSS, and JavaScript files. Server your front-end files from your express application using:
const express = require('express'); const app = express();
app.use(express.static(${__dirname}/../public
));
app.use(express.json());
// Rest of your express app here
