        trim: true,
        minlength: 4

Using express this should be fairly simple:

app.post('/your-route', async ( req, res ) => {
  await YourModel.save({ 
         IP: req.connection.remoteAddress, 
         // other fields
        });
});

If you're behind a proxy or need a more sophisticated approach you can consider using a library like https://www.npmjs.com/package/request-ip to determine the IP-address.

when I run it, I get " IP:"::1" in DB, as far as I understand it means 127.0.0.1, right? Will it work properly ( will I get proper local IP? ) when I run it on other network? – Elvinas Kujelis Nov 29 '20 at 15:49

Yes, since you're using IPv6 you'll see ::1 if you perform the request from your localhost. – eol Nov 29 '20 at 16:01
