OpenAPI + Fastify: let the contract build your server—Martian Chronicles, Evil Martians’ team blog Wire your OpenAPI contract into a Node.js Fastify backend with auto-generated routes, typed handlers, and request validation—no manual route definitions, no type drift, no integration surprises.

You know that feeling when you generate a typed SDK from your API spec on the frontend? No manual types, everything in sync, life is good. Now imagine the same thing but for backend: your OpenAPI spec generates typed route handlers and you just... implement them. Read this walkthrough:

Quite recently, I had a built-in "ad blocker" in a browser remove a full h2 on a docs site, because it had a specific word in it (maybe it was "share" too, forgot). That was the last hit I needed to uninstall it :D

How to Make a DOM Library Render Anything w/ Paolo Ricciuti YouTube video by Syntax

@techniq.dev just made me realize that I'm such an idiot I didn't share my appearance on @syntax.fm here 🤦🏻‍♂️

Anyway here's me chatting with @tolin.ski and @wesbos.com about the svelte custom renderers initiative 🧡

It was so fun...thanks for having me 🙏🏻

Watched March MadCSS and thought "what if we could do this every day?"

So I built it. In a day.

cssdaily.dev — a daily CSS challenge. Write CSS to match a target, get pixel-diffed in real-time. New challenge every morning.

Scoring adapted from @wesbos.com and @tolin.ski's open-source SynHax.

Svelte goes beyond the DOM Svelte is well loved as a web framework, and now the team is working to take it multi-platform. Svelte’s custom renderers API will enable native apps, terminals, and more to be build with Svelte.…

This evening, @paolo.ricciuti.me will join @codetv.dev's The Web Dev Podcast to talk about our work on the Svelte Custom Renderers Initiative! Check it out if you’re interested in rendering beyond the DOM with Svelte 🙌

Recently, someone posted on LinkedIn that skip links are often broken because their target elements are missing a `tabindex` attribute. I was really surprised to see that because I thought that was an issue of the past. That's why I decided to test it.

Oh right! I forgot about animation-range, great stuff!
I will update the article and demo tonight. Thank you!

If only Safari supported `viewport-fit=cover` in Portrait Mode on iOS. The combo with the safe-area insets gives you full control over which colors to use where.

(For completeness: They support `viewport-fit=cover` in Landscape mode on iOS. And on iPadOS they do nothing but the cover behavior)

Thanks Manuel! I wasn't aware the frustration was so obvious, but oh well, it's the truth 😄

The attacks on Iran are illegal

They constitute aggression

Pre-emptive self-defence would only be legal if an attack by Iran was imminent and that’s simply not the case

Iran now has the right to self-defence

Every country can support Iran in exercising its right to self-defence

Define the Theme Color for Safari 26 With theme_color unshipped, what are our options to control the background color of Safari 26 browser UI?

It bugged me that it is not obvious how Safari 26 decides which background color to use for its browser chrome. I wrote about what I found out so far, including a trick to apply a custom theme color and a demo:

Native Random Values in CSS The CSS Working Group has published the Values and Units Module Level 5, which introduces native mechanisms for generating random content using only CSS. This is the tl;dr of a longer article explorin...

CSS is getting native randomness 🎲

random() and random-item() are coming with:

- per-element randomness
- step-based ranges
- shared value options
- zero JS required

I wrote an overview of the feature, how it works, and what browsers support it.

#TIL Safari 26 supports local overrides for network requests.
webkit.org/web-inspecto... suggests this feature existed since January 2020, can this be true?

SvelteKit 2 now fully supports Vite 8

SvelteKit 3 will require it - giving additional optimizations and functionality. E.g. SvelteKit 3 will use @rolldown.rs hook filters to spend more compilation time in rust and less in JavaScript. And SvelteKit 3 adapters use only rolldown without esbuild
