Question

How start app in express js (nodejs)? TypeError:app.set is not a function. Console.log screen

var express = require('express');
var app = express();

app.get('/', function (req, res) {
res.send('Hello World!');
});

var server = app.listen(3000, function () {
var host = server.address().address;
var port = server.address().port;
});

@skypjack, app.set only in bin/www file (default file). var port = normalizePort(process.env.PORT || '3000'); app.set('port', port); — Designlenta Gogo
