   JS library to make your website instant▲426

   http://instantclick.io/ It seems the internet architecture won't bring us instant websites anytime soon. So here is a hack. I released this JS library last month (today is version 2.0 release, fixing v1.0's rough edges), it makes use of HTML5's pushState and preloading to make a website instant. It works like this: before clicking on a link, you'll hover over it. And there's a delay of 200-300 ms between these two events. InstantClick uses this delay to preload a page, when you click on a link it will display instantly in most case. (You can test on the website.) That's…

    Scroll Buddy▲107

    Hi! Instead of a boring scrollbar I made a scuba dude that swims down the page when you scroll. The idea came from nostalgia; remember SkiFree game on Windows? I wanted a skier skiing down my site. Building the skier mechanics in pure javascript turned out to be difficult so I started with a runner, added a santa hat, and recently built scuba buddy. You can try it directly as soon as you start to scroll down the page, and see the other animations with the "Change Animation" button. Technical details: entirely javascript, takes scroll depth value (window.scrollY) and inputs that into…

    floors.js▲215

    Hey HN, I'm Vincent. I built floors.js to bring back social interactions on the web. You paste one script tag. Your pages become isometric 3D rooms. Visitors show up as avatars, see each other, and chat in real-time. Three.js handles the isometric rendering, and a Bun WebSocket server manages presence, rooms and chat. The whole thing runs without touching the host site's DOM or styles beyond its own container. It works on any static site and is also optimised for SPA navigation (clicking on a door lets you navigate to another page). The landing page itself is the live demo, and I'm in the…
