Wrote (with some LLM help!) an article on how to build a progressively enhanced omnisearch input field in SvelteKit! sveltesociety.dev/recipe/build...

Wouldn't it be nice if the `form` remote function could also give you a json schema that you could use to dynamically build your forms? 👀

It was a blast yesterday at @svelte.at @sveltesociety.dev We had 42 people show up! Thanks @sentry.io and @stracke.tech for hosting. Great talks by @michaelaufreiter.com @danirukun.bsky.social and Housein :)

There's a new Svelte Society Barcelona chapter! Let's spread the word!

🎙️ Just published a new episode of Svelte Radio: Custom Renderers for Svelte with Paolo Ricciuti . Have a listen:

🎙️ Just published a new episode of Svelte Radio: One Man Svelte for NGOs with Ilja. Have a listen:

What a naughty developer! We dare you to try it again! Let us know what happens!

Tomorrow, Tuesday December 2nd, at the @sentry.io headquarters in Vienna. See you tomorrow! 👋

🎅🎄🎁 ADVENT OF SVELTE 2025 🎅🎄🎁 24 days, 24 videos with tips, tricks and features you didn't know about we're hitting the ground running with the lesser-known $inspect(...) and $inspect.trace(...) runes (docs: svelte.dev/docs/svelte/...) follow along here! advent.sveltesociety.dev/2025

It's the first day of December... and that means... Advent of Svelte time!

Ready for Advent of Svelte 2025? 👀 advent.sveltesociety.dev/2025

Excited to see the Svelte custom rendering work get a sponsor! Additional sponsors are still required to fund the project, which will let Svelte run with Lynx JS

Just updated the agenda for the @sveltesociety.dev Berlin meetup... 🥁 @dominikg.dev will join us to talk about remote functions (and his secret Guarana gum bears stash) @peterkogo.bsky.social will share his experiences of working on @xyflow.com in Svelte vs React guild.host/events/svelt...

like a lot of obvious-in-hindsight APIs, this took a loooot of trial and error to get right (ignore the deranged screenshot). but very happy with where we landed — this primitive is part of how we extract the secret sauce from SvelteKit and make its powers available to all Svelte apps more to come

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

Nothing to see here, just a few Svelte milestones. For SvelteKit alone I'd need to add 6+ more notable user-land features. I'm thinking about turning this into a less noisy interactive (with links).

With the next release of typescript-eslint, you will be able to setup a new SvelteKit project with every single integration it offers and fast-glob will be nowhere in your dependency tree! Removes over a dozen dependencies like is-number!! github.com/typescript-e...

I'll be speaking about "CMS-Free, Editable Websites with Svelte and Svedit" at next week's Svelte Meetup in Vienna. Very much looking forward to meeting the Austrian Svelte Society. See you there! :) www.meetup.com/svelte-socie...

The upcoming Svedit 0.6.0 (in the works since ~7 weeks) will be a huge step towards API stability. At the heart is the new Command API, that will give you a ton of flexibility to design your own editable websites and apps. Docs are already in the README: github.com/michael/svedit

After way too many rounds of review, `hydratable` is out! This new low-level Svelte API isn’t one you’ll find yourself reaching for often, but it’s extremely useful to libraries. During SSR, function results are serialized alongside your HTML…

Yes, I did, and I still think Formisch can deliver a lot of value. We will soon work on a SvelteKit package so you can reap the benefits of both libraries.

Thanks to the newly relaunched @sveltesociety.dev website, I just saw that @syntax.fm did a deep dive into SvelteKit remote functions sveltesociety.dev/video/svelte...

Streaming file uploads via a custom binary format just got merged into SvelteKit! In a follow up PR (github.com/sveltejs/kit...) upload progress will be handled too! github.com/sveltejs/kit...

Cooking up a SvelteKit adapter that adapts the server parts of Kit to run inside a service worker on the client! 🤯 Here some Pokemon are fetched inside of a load function in a +page.server.ts file... running in the client! :)

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 Gift link: conffab.com/presentation...

We are finally making a svelte skill for claude (and turning the repo into a claude marketplace so you can install the MCP and the skill with two commands). Please check out this PR, there's a zip file with the skill that you can download..try the skill without the MCP and report if it works! 🧡

In Germany, booking a doctor appointment is monopolised by a company which suffered data leaks, didn’t have 2FA, and got caught harvesting data. Really cool to learn about a 1) open-source 2) Svelte / SvelteKit-based alternative! Kudos to the Prototype fund! github.com/open-recepti...
