The native module os can give you some memory and cpu usage statistics.

var os = require('os');

console.log(os.cpus());
console.log(os.totalmem());
console.log(os.freemem())

The cpus() function gives you an average, but you can calculate the current usage by using a formula and an interval, as mentioned in this answer.

There is also a package that does this for you, called os-utils.

Taken from the example on github:

var os = require('os-utils');

os.cpuUsage(function(v){
    console.log( 'CPU Usage (%): ' + v );
});

For information about the disk you can use diskspace
