A historic first today as Opus 4.5 scores 100% on SvelteBench - the first model to do so. We're hard at work on the next version of SvelteBench that will use an agentic approach, if you have feedback, submit it here: github.com/khromov/svel... #svelte #ai

The glob library on npm currently has a CVE. It's entirely predictable since it has 26 dependencies.
If you're getting a security warning from glob it's a good time to see if you can switch to a lighter dependency such as tinyglobby or Node's built-in glob functionality: nodejs.org/api/fs.html#...

When reducing dependencies in Svelte projects, I was really surprised how many dependencies the typical glob library has and ended up switching most of the JS ecosystem to tinyglobby once it became available. With one final PR pending, the Svelte ecosystem is nearly free of extra glob dependencies!
tinyglobby is a great success, and has shown us how much we can improve perf for everyone. here's some of the story!
big thanks to @superchupu.dev and @benmccann.com for putting so much work into this and the migrations/adoption. we're lucky to have both in the @e18e.dev community 💙

SvelteKit 3 / Vite 8 will be built on rolldown. You can use it now if you're adventurous!
If you're not using the new remote functions, it largely works without issue and is much faster.
We'd love help in discovering any bugs that haven't been unearthed yet! Post them at github.com/vitejs/rolld...

Yes! Let's set the record straight. Biome has very little support for Svelte. It's marketing gone overboard. It has no Svelte-specific rules that I'm aware of. I don't think it will ever be a competitive offering. My eyes are on oxlint, which is working towards being able to run eslint-plugin-svelte
> While we’ve done extensive work to handle many patterns, there are cases and framework-specific syntaxes that may not yet be fully supported (for example Svelte control-flow syntax, or Astro JSX-like syntax).
Sooo... Not full support then 😅

I'm a bit pleased to learn that Cloudflare found SvelteKit to be nearly an order of magnitude faster than Next.js. We've invested in Svelte's speed, but not SvelteKit's, so I suspect there's still much more room for improvement.
Oh... what's this, you ask? Just a benchmark that coincidentally shows how fast SvelteKit is compared to Next.js 🤷♂️
How fast, you ask? Just 7-10x. No biggie.
