Real-time Hypermedia - Delaney Gillilan
Building visualizations, dashboards, browser games and content, comes with a huge set of challenges. I build a lot of these things and the challenges are anything but solved. It's not like I'm even looking at the challenges through the eyes of youth. I'm a fledgling grey beard and have seen the industry grow and bloat over the last few decades. No combination of Next, React or new trendy framework is going to solve them and so when HTMX and Alpine made their advances, I fell in love almost immediately. A world heading back to the centrality of Hypermedia is a world I can love again! After a short amount of time, cracks started to appear, and after many ~~debates~~, ~~arguments~~, discussions with the HTMX team, I explored my own approach and eventually it became worthy of its own name, Datastar. It started out as a framework for making plugins for Hypermedia, and today, straight out of the box, it supports all the tooling for making real-time apps in Hypermedia. I promise not to send you to sleep and will show you the approach, how to create the much loved hello world equivalent, a real-time chat app, and the grand finale, a project that is set to change the face of developer education; a 3D city, controlled completely with Hypermedia. You'll see how simple it is, with performance that will remove your eyebrows. From UtahJS Conf on September 13, 2024 in Sandy, Utah www.utahjs.com

Using scroll snap events - CSS: Cascading Style Sheets | MDN
The CSS scroll snap module defines two scroll snap events: scrollsnapchanging and scrollsnapchange. These enable running JavaScript in response to the browser determining that new scroll snap targets are pending and selected, respectively.

Blinksy just learned to redraw itself on Checkboxes when things get out of sync.

Wrote some thoughts about pure UI/ui = fn(state) after spending some time with http://data-star.dev. If you've been feeling modern frontend dev has felt overly complex and the juice isn't worth the squeeze then check this out.
ui = fn(state) done right
If "ui = fn(state)" has ever resonated with you as a frontend developer you owe it to yourself to consider we as an industry have been going about it all wrong for years.
Likely your state already lives on the backend and by syncing it to the frontend to render UI we're adding measurable amounts of unnecessary complexity. If you're to radically simplify if you development environments and production deployments then read on…

By the way, I actually showed Datastar to the client before the RC version. We've already agreed that at one of the development stages, after the main release, we'll switch to Datastar.

God, yes, finally!
I was just working today on a module for a client's project. It's HTMX + Alpine. And I was making it and kept thinking the whole time: DATASTAR!!! This needs DATASTAR! When will RC be ready?
And here it is!
Good job, @bencroker.com, @data-star.dev, Johny and others! 🤌🏻

It’s been an incredible journey, and I feel honoured to be working with people like @data-star.dev and Johnny Stevers. And there’s so much more yet to come!!

This is the difference between intuition and actually looking at metrics y'all
Compression vs diffing it's not as intuitive as you think.
Sending down 2304+ divs (85041 bytes uncompressed ) over SSE and relying on #brotli compression instead of diffing results in a checkbox change being 13 bytes.

Horses for courses. Thanks for taking the time to read the docs!
for the record — having read the docs, i do think datastar is cool. i like when projects pursue their particular visions. im not personally excited about this particular vision but i do like the commitment and i can see other people being quite happy with it
