I created this library if you want to check internet connexion in your module.
This library is very simplified and ready for use in your node_helper.js

This library is used in MMM-Assistant2Display

single node routine for checking internet status

Installation

npm install @bugsounet/internet

Sample with pir contructor

const Internet = require("@bugsounet/internet")

this.config = {
  delay: 10 * 1000,
  scan: "google.com",
  command: "pm2 restart 0",
  showAlert: true
}

var debug = true

this.internet = new Internet(this.config, callback, debug)
this.internet.start()
setTimeout(() => { this.internet.stop() } , 60 * 1000)

function callback(status, value) {
  if (status == "INTERNET_PING") console.log ("Ping:", value)
  if (status == "INTERNET_DOWN") console.log ("Conexion lost... Retry:", value)
  if (status == "INTERNET_RESTART") console.log ("Internet is back")
}
