Yes, you can discern from user agent of request. Write the regex for that yourself or use a ready-made npm module device

code reference:

var device = require('device')
app.get('/', function(req, res) {
    var ua = req.headers['user-agent'];
    if(device.is('phone')){
       console.log('device is phone');
    }else if(device.is('tablet')){
       console.log('device is tablet');
    }else  if(device.is('desktop')){
       console.log('device is desktop');
    }else {
       console.log('device is something else');
    }
});
