A simple Node.js module for accessing the serial number (a.k.a. Dell Service Tag, asset tag) of the local machine. Supports Linux, Mac (OS X), Windows, and FreeBSD. On Amazon EC2 instances, it will return the instance-id.
npm install serial-number
And/or install globally for a serial-number
shell command:
[sudo] npm install -g serial-number
The serial number value is retrieved from the system asynchronously and passed to a callback.
var serialNumber = require('serial-number');
serialNumber(function (err, value) {
console.log(value);
});
