The Great CSS Expansion

CSS now does what Floating UI, GSAP ScrollTrigger, Framer Motion, and react-select used to require JavaScript for. Here is exactly how much that saves, why these libraries were painful beyond their size, and what the platform still hasn't figured out.

Quick #story time: I was on a team which accidentally shipped sourcemaps to production!

The production server would serve sourcemaps for local dev, and we built sourcemaps in prod to deobfuscate errors but they weren't provided to the server in the prod environment.

You might see the hazard there. An innocuous change to our #Bazel build structure accidentally pulled in sourcemaps into the server, which it then helpfully served.

This was an app in the #Google monorepo too, so we were revealing all our source code as well as all our dependencies!

JavaScript Thinks Everything’s a Date, by (not on Mastodon or Bluesky):

JavaScript Thinks Everything's a Date

Popular JavaScript engines have legacy date parsers that will extract a year from nearly any string containing a number. "Route 66" becomes 1966. "Boeing 747" becomes year 747. We explain how the parser works and contrast it with Python.

Ayoo, new supply chain attack dropped. Check your package-lock.json today! I'm running an old version but it's worth a check because, odds are, YOU are running axios somewhere in your stack.
