Determine when a user should be considered inactive or away

inactivity.js

const ioHook = require('iohook'); // For checking system input activity
const logUpdate = require('log-update'); // For writing out to the terminal
const moment = require('moment'); // Time related stuff

let idleTime = moment();

// Listen for all the events we consider activity
ioHook.on("keyup", event => {
  resetIdle();
});

ioHook.on("mousemove", event => {
  resetIdle();
});

ioHook.start();

// Every second, check if they should be considered inactive yet
setInterval(() => {
   logUpdate(`Time since activity: ${moment().diff(idleTime, 'seconds')} \nInactive: ${moment().diff(idleTime, 'seconds') >= 15}`)
}, 1000)

// Set the latest activity time to now
function resetIdle() {
    idleTime = moment()
}
