Chrome 136+ ships a new V8 version that supports a "compile hint", which makes V8 parse and compile all functions in that file eagerly.
Great for entry points – where you know all functions will very likely be used. Less so as 'one weird trick to make all your JS faster'.
🎉 Framer can now simulate DOM sizes and positions on the server, without the real DOM.
This lets us automatically do optimizations that rely on element sizes – like loading=lazy, image preloading*, and content-visibility*.
AFAIK no other site platform supports this today.
(* = soon)
Last week in Framer performance: we shipped AVIF support! Now, all images are served as AVIF, making them 20+% smaller.
AVIF takes ages to encode, tho, so we came up with a clever trick. 🧵
Responsive & performant images are complicated. My first #webperf article really goes in-depth on `<img srcset>` and provides a unique alternative to `<picture>` 📸
If you've learned something new, I'm happy about boost's & your feedback :)
