Service Worker - Offline Page

When the end-user goes offline, it is possible to cache a page to their device to show a custom offline page. Examples of this would be sites such as YouTube and X.

Just use the JavaScript file below, make sure it's at the root of the domain in order for the web browser to pick it up. The HTML file below is an example of an offline page. I would recommend building your own custom offline page to tailor it for your website or web application.

Number Keyboard for Mobile Devices

When it comes to creating a number input, we would create an <input/> with the type attribute set to number. This makes arrow buttons show up that can let us go up and down.

On mobile, we don't want this. It's expected by the end-user that their numberic keyboard shows up, so we set the inputmode instead.

Straight-forward setup for Zot in Docker. Steps are also included how to use it as a Docker registry.

Setup Zot in Docker

This is mostly how SudoVanilla's Docker registry is setup.

I'm still new to Zot, so some information below could be inaccurate and some important information could be missing too.

This is kinda like including a component in a JS framework using the "import" function, but with vanilla JavaScript.

1	function includeHTML() {
2	var z, i, elmnt, file, xhttp;
3	z = document.getElementsByTagName("*");
4	for (i = 0; i < z.length; i++) {
5	elmnt = z[i];
6	file = elmnt.getAttribute("include-html");
7	if (file) {
8	xhttp = new XMLHttpRequest();
9	xhttp.onreadystatechange = function() {
10	if (this.readyState == 4) {

SudoVanilla Ark and Commit Signing

Sign commits when pushing to SudoVanilla Ark and other Forgejo/Gitea instances.

Generate SSH Key

Generate a new SSH key using the ssh-keygen key. We'll name it ark so we know in the future that this key is used for SudoVanilla Ark or whatever you originally planned to use it for.

Run:

ssh-keygen -o -f ~/.ssh/ark -a 100 -b 4096 -C "KeyName"
