The way you build web pages—using IntersectionObserver, for example—can have a direct effect on the climate emergency.
Webpages can be good citizens of battery life.
It’s important to measure the battery impact in Web Inspector and drive those costs down.
This is a spot-on analysis of how CSS-in-JS failed to deliver on any of its promises:
CSS-in-JS was born out of good intentions — modularity, predictability and componentization. But what we got was complexity disguised as progress.
React is no longer just a library. It’s a full ecosystem that defines how frontend developers are allowed to think.
Browsers now ship View Transitions, Container Queries, and smarter scheduling primitives. The platform keeps evolving at a fair pace, but most teams won’t touch these capabilities until React officially wraps them in a hook or they show up in Next.js docs.
Innovation keeps happening right across the ecosystem, but for many it only becomes “real” once React validates the approach. Which is fine, assuming you enjoy waiting for permission to use the platform you’re already building on.
Zing!
The critique isn’t that React is bad, but that treating any single framework as infrastructure creates blind spots in how we think and build. When React becomes the lens through which we see the web, we stop noticing what the platform itself can already do, and we stop reaching for native solutions because we’re waiting for the framework-approved version to show up first.
If your team’s evolution depends on a single framework’s roadmap, you are not steering your product; you are waiting for permission to move.
A very, very deep dive into like-for-like comparison of JavaScript frameworks. The takeaway:
Nuxt demonstrates that established “big three” frameworks can achieve next-gen performance when properly configured. Vue’s architecture allows competitive mobile web performance while maintaining a mature ecosystem. React and Angular show no path to similar results.
And the real takeaway:
Mobile is the web. These measurements matter because mobile web is the primary internet for billions of people. If your app is accessible via URL, people will use it on phones with cellular connections. Optimizing for desktop and hoping mobile is good enough is backwards. The web is mobile. Build for that reality.
React exists as a profound perversion of the web platform. React has failed upwards to widespread adoption because it provides a “developer experience” that bypasses the hard parts. Like learning HTML, or CSS, or JavaScript. Even learning React itself is discouraged; that’s for adults, you should use meta-frameworks. React devs are burdened with multi-megabyte monstrosities before they’ve written a single line of code. You cannot fix “too much JavaScript” with more JavaScript and yet React devs are trained to
npm installuntil their problems become their users’ problems.
When I set about writing this article, I intended it to be a strong argument for progressive rendering. But after digging into it, my feelings are less certain.
This line-up just gets better and better! You’ll want to be in Brighton on March 12th, 2026.
Technically, websites can do just about anything that native apps can do. And yet the actual experience of using the web on mobile is worse than ever.
A redesign with modern CSS.

Safari 18 supports `content-visibility: auto` …but there’s a very niche little bug in the implementation.
