A couple of weeks ago at @perfnow.nl I gave a talk called "Fine-grained everything". It's about @svelte.dev (obviously), and the new frontiers of framework-land, but it's also about some stubborn misconceptions in web performance circles

Fine-grained everything
<p>Modern frameworks like Svelte are fast thanks to signal‑based fine‑grained reactivity, but performance is more than 60fps. This talk covers new approaches to build fast, reliable, data‑efficient ap...

today we landed a @svelte.dev feature i'm pretty stoked about — we call it 'forking', and it lets you run state changes offscreen and later choose whether to commit them (e.g. user hovers on a link, preload data in case they click)

I've open sourced Ripple!

It's super early days, not much works and there's little to no documentation or guidance. Plus the codebase is raw, but I at least wanted to share my ideas with the community. :)

svelte kinda stopped marketing performance as a feature because "react is fast enough" but... it just isn't. so many of these stories. maybe the compiler will fix it.
anyway the real money quote is "Features that took days in React could be built in hours with Svelte". many such cases!

So, some of you may know that recently I'm working full time on the svelte renderer API thanks to the company I work for ( @mainmatter.com ).
This will unlock using Lynx to build native applications with svelte.
There's still a lot of work to do but isn't a counter the mother of all apps? 🧡😍

Day 8 — we're calling this 'function bindings'. You know how you can do `bind:value={value}`? You can now do this...
bind:value={getValue, setValue}
...which lets you transform and validate data

Running a project pilot on dropping component / service / directive file and class suffixes in a huge enterprise app (required just some eslint adaptions in our case)!
So far only positive feedback!
I hope we'll make it... and end up with "We Are Never Ever Getting Back Together"! 😂

With #Angular 19 launching next week, the focus will shift.
If the experiments 🧪 about the new authoring format have their comeback 💯, let’s not forget one of the many reasons:
The Angular team shouldn’t have to build a TypeScript dialect for templates.
