With the ever expanding capabilities of AI to bang out more and more code, I'm curious to see if the debugging abilities will grow in the same vein.

Got bundling JSR/Deno code with Rolldown working. This is using Rolldown's and Deno's crates respecting Deno's lockfile, config discovery, and resolution. Finally Deno's crates have been refactored enough for this to be feasible (~500 LOC). I'll update with more details later.

Signals now support new `watched` and `unwatched` options. You can consider watched a lazy subscription, when the signal is first accessed it will trigger. When the last subscription is removed, unwatched will trigger.

Been playing around a lot with the canvas API lately for some visualizations. It takes a little to get used to as the thinking is a little different, but I'm really liking it. It's quite cool to throw a lot of data at it and barely see any perf impact.

NPM downloads of course signify very little and are heavily inflated by CIs and scrapers, but... it looks like Preact has exceeded 6m downloads per week which is pretty neat: npmtrends.com/preact

There was a wave of Unicode shenanigan issues reported to toolchains some time ago, and our position was that the right places to address them are editors and code review tooling. VS Code does try. Unfortunate that GitHub doesn't.

A song on Spotify played the slack notification sound as part of the track and I thought I was going mad when I couldn't find new messages in slack. That's diabolical, but fair play to you whoever did this!

Does anyone have any frontend-focused demo apps they particularly like? Ideally supported by a pretty simple server if one's needed. I'd like to write up some more Preact demos, showing various app patterns that some users may be unfamiliar with, but struggling to find good existing examples.

It's 2025 and we're still all at each others throat about RSC, front-end frameworks, ... At some point we should acknowledge that every approach has its tradeoffs and that at the end of the day we all have our preferences

As much as I love vite, it feels like it needs a more systematic approach to make sure that it is a little more careful when processing untrusted user input. Most past CVEs seem to be a variant of the same vuln.

I wanted to write something like this so many times when I was at Netlify! We always decided it was best to not make a fuss. Now I'm not at Netlify, I still believe abstracting the hosting layer via adapters makes for better framework architecture overall, as well as being better for the ecosystem.

I'm noticing more and more that folks seem to seek out permission to open a GitHub issue, like: "Functionality AB doesn't work" "This looks like an unexpected behavior. I'd classify this as a bug. Can you open an issue?" "Sure, I just wanted to check if this is a real issue first"
