htmx 4.0 Launches Exclusively as a Game Boy Adventure

I am releasing htmx 4.0 not as a standard library, but as a playable game on the Game Boy. Players must navigate four levels of pickle-collecting excitement, squish client-side JavaScript to fit the screen, and avoid slop. If you have the skills to defeat Warren, you will unlock the actual htmx 4.0 source code.

HTMX 4.0, the first JavaScript library to release exclusively on the Game Boy platform!

    I've been using htmx for three years now, and it's completely unlocked new ways of building software for the web, especially if you use a server-side templating language.

    But more importantly (as this "Game Boy" option reveals), the head honcho is really responsive with the items in the store. I had purchased a coffee mug a few years back and complained on Twitter that they need to sell larger mugs instead of only offering little tiny baby mugs that only hold ~8 ounces of liquid. The next day, he added giant 48-ounce monsters to the store and I've been drinking out of that mug every day since.

    HTMX's whole vibe is amazing. It's good tech, kept simple, useful in gobs of situations, but doesn't take itself too seriously. I've used it in professional and side projects since intercooler.js, and still love it. Here's a crazy unicorn-laser-eyes mug[0] that evokes the vibes of NROL-39[1]. I adore it.

    I was at Big Sky Dev Con when they unveiled the GameBoy game. I kid you not my jaw dropped. I thought it was some sort of like emulator gimmick until they said "everyone can take a physical cartridge home!"

    One of the most delightful little swag stunts I've ever seen, and emblematic of the HTMX crew just how much they care about craft and delight in everything they do.

    I love HTMX and use it in a few projects, but its amusing how whats old is new again. .NET Framework / Web Forms had update panels to do partial rendering of web pages back in 2005. Outside of .NET developers it got a lot of hate. But to a certain extent HTMX is a super well refined and more capable version of update panels and more.

    HTMX is awesome. I've replaced several OSS web apps on my home server with HTMX + Go + PostgreSQL replacements. The results are lightweight, responsive, work great on desktop and mobile alike, all with the absolute minimum complexity required. The codebases are easy to understand and modify, and so far I'm going months between updates (mostly just minor bugfixes for my applications). I fully expec my mature apps will go years if not decades between required upgrades.

    Thank you to the HTMX-folks for keeping software fun! I've been a happy HTMX user and Grug essay forwarder since it first made the rounds here on HN. This was an instant purchase :)

    Is it true that the person who authored the "Grug-brained developer" essay also created HTMX?

    Amazing... an HTMX thread without any haters interjecting or critics telling everyone why HTMX wont work.

    Even React-aholics have to tip their hats to a Game Boy release.

More from this day
