00:00 - With the new Navigation API, you can now show the native spinner + stop button for any asynchronous operation - all you need is a Promise.
00:00 - Please don't import SVGs as JSX. It's the most expensive form of sprite sheet: costs a minimum of 3x more than other techniques, and hurts both runtime (rendering) performance and memory usage. This bundle from a popular site is almost 50% SVG icons (250kb), and most are unused.
- Should I use SSR? What about Rehydration? Where should we implement logic and rendering in our applications? Answers: developers.google.com/web/updates/20…
- HTM 2 is here! 🎉 ⚡️ 20x faster (seriously) 🦄 Custom JSX parser 🤠 under 700 bytes 🤫 compiles to nothing github.com/developit/htm/…
- 🦖 HTM: JSX without the transpiler. 700 bytes to run in the browser, or compile it away using babel-plugin-htm. (works with any VDOM library!) github.com/developit/htm
- Please don't open issues on JS repos asking why they aren't written in TypeScript :(
- ⚛️ Preact X is here. The @preactjs team spent over a year rewriting Preact, and it's finally ready. github.com/preactjs/preac…
