Tampermonkey Automatic Website Refresh

May 21, 2024 at 16:04

I was waiting for a weed delivery today and realized that login cookies were preventing a simple web-scraping bot or a Change-Detection check. The delivery was due in three hours, and I wanted to stay on top of progress updates so I could be ready outside when they arrived.

So, I made a simple Tampermonkey script that toggles auto-refresh on any site. There are existing browser extensions for this, but I don’t trust random internet strangers enough to allow them the necessary permissions. So, here we are. Hit CTRL+SHIFT+Y to toggle. “Y” can be changed to whatever.

Auto Refresh Page with Toggle

    (function() {
        'use strict';

        // Set the interval time in milliseconds (60000 ms = 1 minute)
        var interval = 60000;
        var enabled = false;
        var intervalId;

        // Function to start the auto-refresh
        function startAutoRefresh() {
            intervalId = setInterval(function() {
                location.reload();
            }, interval);
            console.log('Auto-refresh started');
        }

        // Function to stop the auto-refresh
        function stopAutoRefresh() {
            clearInterval(intervalId);
            console.log('Auto-refresh stopped');
        }

        // Toggle function
        function toggleAutoRefresh() {
            enabled = !enabled;
            if (enabled) {
                startAutoRefresh();
            } else {
                stopAutoRefresh();
            }
            alert('Auto-refresh ' + (enabled ? 'enabled' : 'disabled'));
        }

        // Adding a keyboard shortcut (Ctrl+Shift+R) to toggle auto-refresh
        document.addEventListener('keydown', function(e) {
            if (e.ctrlKey && e.shiftKey && e.key === 'Y') {
                toggleAutoRefresh();
            }
        });
    })();
