const path = require(‘path’)
// create the express app
const app = express()
// create middleware to handle the serving the app
app.use("/", serveStatic ( path.join (__dirname, ‘/public’)))
// serve index by default
app.get(’/’, function (req, res) {
res.sendFile(__dirname + ‘/public/index.html’)
})
// Create default port to serve the app on
const port = process.env.PORT || 5000
app.listen(port)
// Log to feedback that this is actually running
console.log('Server started on port ’ + port)
