How to run multiple express servers on different ports?
You need to create multiple app instances from express. Below is the code snippet to start multiple server on different ports from same file.
var express = require('express');let app1 = express();let app2 = express();app1.listen(3000, () => { console.log("Started server on 3000");});app2.listen(3002, () => { console.log("Started server on 3002"); });
You are using window.setInterval instead of window.setTimeout, that's why is running multiple times.
