Wake me up when it's out!

FactorioReminder.js

/*

HOW TO RUN:

- Download and Install node.js. Check by running: node -v
- Create a folder "wakeup" and stick this index.js inside
- cd to the folder. On a mac, this might look like: cd Desktop/wakeup
  no idea on a windows, I think it's something like: cd C:\Users\username\Desktop\wakeup
- Run: npm install request
- Run: npm install sfx
- Run: node index (to stop it, use cntrl-C or cntrl-D depending on your system.)
- Should have an alarm go off when the new update is out!

DON'T FORGET TO SET THE SOUND_FILE BELOW

Options: If you want to be waken up in case there are errors in the program, use "WAKE_UP_AFTER_ERRORS"

Set this to the number of errors in a row before being woken up. I recommend 10, but by default it's off at 0.

  if (WAKE_UP_AFTER_ERRORS > 0 && errors >= WAKE_UP_AFTER_ERRORS) {
    playAlarm();
