Introducing Preact Signals: a reactive state primitive that is fast by default. ✅ feels like using plain values 🥳 automatic updates when values change ⏱ updates DOM directly (fast!) 🥹 no dependencies arrays preactjs.com/blog/introduci…

@TheLarkInn And then the bonus was that doing it as a bundler plugin meant it had to be fast, which forced decisions like doing it all via a Rust lexer (no ast), and those all got reused to build the codemod tool that we then used to stamp the barrels out of the source after.

@TheLarkInn This got us to the end goal fast, but the main value was that it uncovered all of the incredibly nuanced bugs we had when barrel files were removed - module trees shifting between bundles, their exec timing changing, etc.

LOL I'm going to rip out every barrel module from 14 million lines of TypeScript 😂. This is going to be a wild time.

ast-grep is so good I know I can trust software maintained by Hatsune Miku

@kanavtwt it's spelled "Jason"

Day 1 of vibecoding

Soon you will be able to roll Preact in vite without Babel github.com/preactjs/prefr…

What if a signal on the server could just be a signal on the client? Wrote about @_developit's mixed-signals - it reflects server-side Preact Signals to clients over any transport. Write your state once as a model, decide where it runs. No fetch glue. No cache invalidation. Just signals. jovidecroock.com/blog/mixed-sig…

@wesbos lol yeah. though... I'd lay partial blame at the feet of CSS for that specific one haha

@_developit I feel like every site I visit has accidental horizontal scroll

Has anyone else noticed mobile frontends (native and web) are getting increasingly terrible (as we descend into UX vibe coding?)? I keep noticing I've developed ridiculous coping strategies like constantly copying input to clipboard in case it gets lost when sending.

@jbscript or the copyright that tells you what year the LLM training data was collected rather than the date the page was last updated

@_developit New hobby: pressing End to jump directly to the end of landing pages which look like one of the 5 designs every LLM will spit out, and watching the obligatory scroll fade fall apart as I scroll up

@QuentinMerabet why test when you can RALPH

@_developit 100%. It feels like nothing is even tested anymore. wtf?

@cultheroro @wesbos probably comes from the same vendor on the same boat anyway

@wesbos @_developit the home depot app is so fucking slow it's unusable. I literally wanted to buy something from them. My ADHD wouldn't let me wait. Now my cat 5 cable comes from amazon. This is on them.

@rossmorsali lol maybe that's the shift - I'm using more frontends from the folks building LLM stuff, and that stuff is all rushed

@_developit I've resorted to similar techniques for very popular web frontends too, directly from the makers of LLMs

@ryanflorence its been going downhill for sure, but really feels like it's accelerated

@_developit i've felt this for over half a decade

@fnthawar If you haven't seen it, the Baroness Von Sketch Show is fucking hilarious (I assume this is a clip from it) gem.cbc.ca/baroness-von-s…

Nailed it

@georgeranch both. I routinely set up and steer serious/large PR work on my phone while I wander around the house trying to feel unchained from the desk

@_developit For serious work? I use to code on my phone too but for POCs nothing serious.

I've been coding on my phone since 2010, what are people so confused about

@NFS__21 lol good god no. I built a nice web app at work for agentic development. For personal stuff I suffer through Codex Web and Claude Code Web (bleeeeeeeeeh). Back in the day though: phone with a keyboard and a shitty text editor.

@_developit Termux ?

Figured I'd open source the little preact+signals mastodon client I wrote a few years ago, in case the code is useful to folks. It's called Mastodawn.com - a streaming, offline-first installable Mastodon web app that weighs under 100kb. github.com/developit/mast…

@aidenybai add Preact! same JSX element annotation as React but the tree is live and hangs off `__k` on the render root element.

Introducing element-source Get the source file location of any DOM (or native!) element Works w/ React, Vue, Svelte, and Solid
