Is it possible to run 2 applications at the same time in the same main file?

Is it possible to run 2 applications at the same time in the same main file? If so, how?

You can just call express twice

const express = require('express')

const app1 = express()
app1.get('/', function (req, res) {
  res.send('foo')
})
app1.listen(3000)

const app2 = express()
app2.get('/', function (req, res) {
  res.send('bar')
})
app2.listen(3001)

You can have multiple apps and call listen on them separately. Alternatively if you want to serve an app using HTTPS and redirect HTTP to HTTPS you can use the following:

const express = require("express");
const https = require("https");
const http = require("http");

const serverOptions = {
	cert: fs.readFileSync("/path/to/cert"),
	key: fs.readFileSync("/path/to/privkey")
};

const app = express();

// add your routes to app

// Main HTTPS server
const server = https.createServer(serverOptions, app).listen(443, () => {
	console.log("HTTPS server running");
});

// Start server on port 80, which will redirect users to HTTPS
http.createServer((req, res) => {
	res.writeHead(301, { "Location": config.url + (req.url || "/") }).end();
}).listen(80, () => {
	console.log("Redirect to HTTPS running on port 80");
});

// with another app
const app2 = express();
// add routes to app2
const server = app.listen(8081, () => {
	console.log("app2 HTTP server running");
});
