Dated Site Closed Script

site-closer.js

// DATED Simple Site Closer script v0.1
// This script shuts down certain pages automatically on some dates, expressed as regular expressions of ISO8601 datestamps!
// With thanks to MelonKing's original version: https://melonking.net/scripts/site-closer.js
//
// How to use:
// Just place this script in the head of any page you'd like to close!
// Make a page called closed.html and put your closed info on there!
//
// Add this code after you link the script:
// <script>
// 	sc.closedPage = "closed.html"; // Optional: change the closed page url
// 	sc.closedDays = [/^2026-01-01/, /^2026-12-../, /^....-..-01/]; // Specify the dates you'll be closed; syntax explained below
// 	shutItDown();
// </script>
//
// closedDays are all regular expressions. But you don't need to know regular expressions to use this!
// Just remember that each date looks like this:
// /^....-..-../
//   yyyy mm dd
// Replace the dots with the yyyy-mm-dd date you want to be closed.
// Anything that's still a dot is a WILDCARD. So the following are all valid:
// /^2017-..-../   =   closed all of 2017!
// /^....-..-01/   =   closed on the first of every month
// /^....-04-01/   =   closed every 1st of April
// /^2020-01-01/   =   closed 1st of January 2020
//
// You can list as many dates as you want, separated by commas. Just remember the starting /^
// and the ending / - they're important!

let sc = {};
sc.closedPage = "closed.html";
sc.closedDays = [];

// Trigger this site closer!
function shutItDown() {
  sc.dayNow = new Date().toISOString();
  const closedToday = !!sc.closedDays.find(matcher=>today.match(matcher));
  if(closedToday) {
    console.log("Gordon Ramsay screams: Shut it Down!!!");
    window.location.replace(sc.closedPage);
  }
}
