Baseline 2026 brought a wave of new interoperable web platform APIs. Not the kind of big where everything changes overnight. The kind where APIs that have been experimental for years finally ship in every browser. Baseline means you can use them in p...

Astro 7, released June 22, 2026https://astro.build/blog/astro-7, is a speed release. The .astro compiler got rewritten in Rust, the Markdown pipeline got rebuilt in Rust, and the bundler switched to Vite 8 with Rolldown. It is the same framework on f...

If you've ever built a search endpoint, you've hit this wall. Your query has filters, sort orders, a nested set of facets, maybe a geo bounding box. It doesn't fit in a URL, and cramming it into query string params is ugly and fragile. So you reach f...

There was a time when loading React from a public CDN was a real performance trick. If enough sites pulled the same react.production.min.js off the same CDN URL, a first-time visitor to your site stood a good chance of already having it cached from s...

A while back I wrote about configuring this site for AI discoverabilityhttps://morello.dev/blog/configuring-my-site-for-ai-discoverability: raw Markdown mirrors, llms.txt, an AI stance in robots.txt. All of that is about making a site readable. An ag...

Every page on this site ships with its own Open Graphhttps://ogp.me/ image, the little card that shows up when you paste a link into Slack, X, or iMessage. None of them are drawn by hand. Each one is generated at build time by two tools working in se...

You've probably used an AI coding assistant by now. Copilot finishes your lines, Cursor rewrites your functions, Claude Code debugs your PRs. They're all variations on the same idea: an AI that lives inside your editor and helps you write code faster...

Every package manager has a moment where you just wait. You add one dependency, or you pull a branch and run install, and there's a beat where the terminal sits there doing file I/O while you tab away. pnpmhttps://pnpm.io already made that beat short...

If you've worked in a large TypeScript codebase, you know the feeling. You save a file, tab away, and wait for the red squiggles to catch up. On a big monorepo, tsc --noEmit in CI is the slow step everyone learned to stop watching. The type checker w...

I've shipped React for the better part of a decade. Hooks, Suspense, Server Components, the whole tour. So when the SolidJS 2.0 beta showed up in my feed with the tagline "The is Over,"https://github.com/solidjs/solid/releases/tag/v2.0.0-beta.0 I ro...

In my first look at SolidJS 2.0https://morello.dev/blog/solidjs-2-react-developers-first-look I said first-class async was the real story, then barely opened the box. This post opens it. Here's the short version. In Solid 2.0 a promise is just anoth...

If you've ever stashed half-finished work to review a PR, or lost a train of thought switching branches, you should know about git worktrees. They've been in git since 2015, but most developers I talk to have never heard of them. The problem with br...

You render some markdown, get back a pile of unstyled HTML, and then you style it. Headings, paragraphs, lists, tables, code. You do it for the blog. Then you do it again for the docs. Then a third time for the chat UI that streams model output token...
