In Express you can use   res redirect  http   example com     to redirect user from server    To include a status code 301 or 302 it can be used   res redirect 301   http   example com

If you are using Express  the cleanest complete answer is this  const express   require  express   const app       express    app get       req  res    gt         REDIRECT goes here   res redirect  https   www YOUR URL com        app set  port    process env PORT    3000   const server   app listen app get  port         gt

You can use res render   or res redirect   method to redirect to another page using node js express  Eg   var bodyParser   require  body-parser    var express   require  express    var navigator   require  web-midi-api    var app   express     app use express static   dirname          app use bodyParser urlencoded  extend true     app engine  html   require  ejs   renderFile   app set  view engine    html    app set  views     dirname    app get      function req  res       res render  index           This reponds a post request for the login page app post   login   function  req  res        console log  Got a POST request for the login        var data              email   req body email           password   req body password             console log data          Data insertion code     var MongoClient   require  mongodb   MongoClient      var url    mongodb   localhost 27017         MongoClient connect url  function err  db            if  err  throw err          var dbo   db db  college            var query     email  data email            dbo collection  user   find query  toArray function err  result                if  err  throw err              console log result               if result 0  password    data password     res redirect  dashboard html                else    res redirect  login-error html                db close                                  This responds a POST request for the add user app post   insert   function  req  res        console log  Got a POST request for the add user         var data              first name    req body firstName           second name    req body secondName           organization    req body organization           email   req body email           mobile    req body mobile              console log data          res render  success html   email data email password data password               make sure that Service Workers are supported  if  navigator serviceWorker        navigator serviceWorker register  service-worker js    scope                 then function  registration                console log registration                       catch function  e                console error e                else       console log  Service Worker is not supported in this browser            TODO add service worker code here if   serviceWorker  in navigator        navigator serviceWorker          register  service-worker js            then function     console log  Service Worker Registered           var server   app listen 63342  function           var host   server address   host      var port   server address   port       console log  Example app listening at http   localhost  s   port        Here in the login section  If the email and password matches in the database then the site is directed to dashbaord html otherwise we will show page-error html using res redirect   method  Also you can use res render   to render a page in node js
