   JavaScript-free (X)HTML Includes▲211

   (spoiler: its XSLT) I've been working on a little demo for how to avoid copy-pasting header/footer boilerplate on a simple static webpage. My goal is to approximate the experience of Jekyll/Hugo but eliminate the need for a build step before publishing. This demo shows how to get basic templating features with XSL so you could write a blog post which looks like My Article some content hello hello Some properties which set this approach apart from other methods: - no build step (no need to setup Jekyll on the client or configure Github/Gitlab actions) - works on any webserver…

    A stab at building my own string diffing library▲29

    Took a stab at building my own string diffing JS package. I built an interactive demo for TypeIt’s website (https://typeitjs.com/build-your-own) a while back. The approach I took to handle user input necessitated a way to calculate the difference between the versions of a user’s text input. I searched around for a package to help me out and found a couple of good ones (like fast-diff), but I either didn’t really like their API or didn’t want to take on a huge new dependency. Instead, I thought I’d give it a shot myself (famous last words). I dove into it having no real formal…

    A simple Wordle clone in 60 lines, using Hyperscript▲111

    Hello HN! I've been playing a lot with https://hyperscript.org/ recently (not to be confused with the other hyperhype hyperscript). I threw together a quick Wordle clone in an evening to see what it would look like using this language. The main functionality that is missing is checking for invalid words. The word dictionary is also very small, so it's very easy. The goal here wasn't really to create a good version of Wordle, it was to build 80% of Wordle in a different language to see what it looks like. Turns out, it looks pretty good! Stuff like using CSS rule precedence to…
