Type performance optimization will always be under appreciated because it’s not the problem people think exists It’s very important for complex type library as it can choke language server At the certain complexity point, your library will not be usual at all if not careful

For those asking about perf and interop, I'll be giving a talk about how it works at ViteConf in Oct. You should all come! x.com/ViteConf/statu…

⚡ Speaker highlight: Jim Dummet, Core Team at @OxcProject As a JS Developer, every tool seems to be rewritten in Rust. But If our tools migrate to a different language, will we lose the ability to customize them? @overlook_motel explains how Oxc is aiming to "square the circle"…

Preact-iso now has it's URL pattern matching logic ported to multiple languages! You can now preload JS and CSS for your app from Python, Go, PHP or Ruby.

What if client side routers URL pattern matching logic was available in multiple languages? Non-JS servers could figure out which client route matches for a request and add preload tags to preload assets (CSS, JS, images, icons) instead of just serving the app shell.

gotta love that the code sample introducing GitHub Spark is a typical unruly horror of hooks mess. Using AI to generate this shit doesn't make it less shit. Use something better.
