cannot get baseboard serial number in nodejs

I am running ubuntu in vmware. I am trying to get the baseboard serial number.

var si = require("systeminformation");
console.log(si.baseboard().serial);

It return undefined. Is the problem in my code? Or the problem is ubuntu is running in vmware?

I find that I can use serial-number to get an unique number even on virtual machine.

var serialNumber = require('serial-number');

serialNumber(function (err, value) {
 console.log(value);
});

To complete AKX answer, si.baseboard() returns a Promise (since v3), so you have to do something like this:

si.baseboard().then(el => console.log(el.serial))

or, if you want to stick with callback syntax

si.baseboard(el => { console.log(el.serial) })

Note for me, it returns an empty string if I launch the script as a regular user. I can display the serial number only if I launch it as root.

You can see here in the systeminformation source that it's reading the file /sys/devices/virtual/dmi/id/board_serial (if running dmidecode -t 2 2>/dev/null fails).

If you cat /sys/devices/virtual/dmi/id/board_serial in your shell (if it even exists), what do you get?

If it's empty or non-existent, then the data isn't provided by your environment.
