Integration with Google Calendar?

Thanks @Ollie and @DamianMontero for your answers, I appreciate!

Do you think I could use a Google Apps Script function to get the daily calendar (as shown here https://www.youtube.com/watch?v=sm1-l5-z­3ag

) and then call the script from Espruino?

I tried this:

var WIFI_NAME = "WIFI_NAME";
var WIFI_OPTIONS = { password : "WIFI_PASSWORD" };
var GsToken='YOUR GOOGLE APPS SCRIPT TOKEN HERE';

var wifi;

function getCalendar()
{
  var options = {
    host: 'https://script.google.com',
    port: '443',
    path:'/macros/s/'+GsToken+'/exec',
    protocol: "https:",
    method:'GET',
    headers: {
      "Content-Type":"application/x-www-form-u­rlencoded"
    }
  };

  console.log("Connecting to Google");
  require("http").request(options, function(res)  {
    console.log("Connected to Google");
    var nRecv = 0;
    res.on('data', function(data) { nRecv += data.length; });
    res.on('close', function(data) {
      console.log("Google connection closed, "+nRecv+" bytes received");
      setTimeout(getCalendar, 10000); // once every 10 seconds
    });
  }).end();
}

function onConnected(err) {
  if (err) throw err;
  wifi.getIP(function(e,ip) {
    console.log(ip);
    getCalendar();
  });
}

var Inited=false;
function Init()
{
  if(!Inited)
  {
    Inited=true;
    wifi = require("Wifi");
    wifi.connect(WIFI_NAME, WIFI_OPTIONS, onConnected);
  }
}
function onInit() {
  setTimeout("Init();",1000);
}

Init();

The console output is

Then nothing happens. I think I am pretty close to have a solution not based on a third party service, but, well, it doesn't work as is... I don't know if ESP8266 can do https requests directly or if I need to use some kind of HTTPSRedirect library, used on the Arduino world...
If anyone has any hints to help me go a step further, that would be awesome :-)
