📣 Just Scheduled Could Svelte power terminal and native apps? OSS maintainers working on the customer renderers API are aiming to make multi-platform Svelte a reality. @paolo.ricciuti.me talks through what it takes to make this ambitious API, a reality. Details: www.youtube.com/watch?v=nPac...

Who here is on Svelte 4 yet? Curious to hear what is stopping you from upgrading to Svelte 5, and if we can make things any easier here.

SvelteKit 2 now fully supports Vite 8 SvelteKit 3 will require it - giving additional optimizations and functionality. E.g. SvelteKit 3 will use @rolldown.rs hook filters to spend more compilation time in rust and less in JavaScript. And SvelteKit 3 adapters use only rolldown without esbuild

LET'S GO SVELTE

Almost 3 years since editable.website won 2nd place at @sveltesociety.dev SvelteHack. Since then, I’ve been busy turning this from a prototype into something solid. A way to build CMS-free, in-place editable websites using only Svelte. This is v2. 🥳

What makes Svelte the right choice for modern frontend projects? And when is it not? In this blog post, @paolo.ricciuti.me breaks down the advantages and limitations of Svelte, and what that means for your next product decision. Read the post 👉 mainmatter.com/blog/2026/02... #svelte #sveltekit

Sometimes people ask me why I picked svelte...I put my thoughts in words here and no, it's not just a technical thing. This is my love letter to svelte 🧡

New in Svelte: Comments inside component/element tags!

New LayerChart docs 🎉 next.layerchart.com Massive overhaul including over 700 isolated examples with browsing / cross referencing / StackBlitz editing, AI friendly (llms.txt), component API docs, guides, improved search, showcase, improved design, and more! Details👇

Yesterday we introduced our new @svelte.dev starter kit, today we're bringing our stream package on board: npm i @laravel/stream-svelte Easiest way to consume streamed responses from your backend in your Laravel + Svelte app, hands down www.npmjs.com/package/@lar...

We just released a number of security patches across the Svelte ecosystem. If you use SvelteKit, the Vercel adapter for SvelteKit, Svelte, or devalue, you should upgrade. The Vercel OSS Bug Bounty paid out over $14,000 for these reports!

php is cool now

Welcome to the party, @svelte.dev New starter kit just dropped: Laravel + Svelte + Inertia

🌾 Rich Harris (@rich-harris.dev), creator of Svelte, joins @podrocket.bsky.social to unpack Fine Grained Everything and what comes after React Server Components: why better primitives beat micro-optimizations and what this means for frontend architecture: youtu.be/isp32w1uJ3k?...

svelte-check just got much faster We've added --incremental and --tsgo as new options to speed up Svelte type checking

Someone built a roguelite using @threlte.xyz 🤯

I've setup better-auth in many projects and tbf their docs focus too much on the client side (which is wild for an auth library)...that's why I'm excited about this sv release: it adds auth to your SvelteKit project and it does it right..using the server! Will try to PR better-docs to better-auth 😄

It's official, you can now get paid up to $10,000 for finding security issues in Svelte and SvelteKit! Big thanks to both the security team at Vercel and the Svelte maintainers' group for coming together to make this possible. Learn more: vercel.com/blog/the-ver...

Soon.

I cover quite a lot of ground in this talk, but the bit I hope people take away from it is that AI-driven development poses dangers that we're not talking about nearly enough. This clip was recorded before we knew how prominently Elon features in the Epstein files: 🎞️ youtube.com/clip/UgkxImh...

you know what to do --> npmx.dev/package/svelte

TypeScript never ceases to amaze me

If you're building something for Svelte, writing something or producing videos - you should submit them on the Svelte Society website. It's the go-to place for Svelte stuff. Oh, and you might get showcased in the newsletter as well!

Back from parental leave! Eager to get back to work but also a bit sad to not have as much time with my children anymore - mixed feelings, but excited nonetheless

Svelte skills, now part of the opencode plugin. What Paolo left out btw is how he proposed that capability to the opencode folks and helped refine the API for it - goated.

It took a while, lots of debugging and fixes in rolldown, vite-plugin-svelte and sveltekit, but today it happened. For the first time, sveltekit tests in vite-ecosystem-ci for vite-8 beta passed. github.com/vitejs/vite-... Thanks to everyone who helped getting there especially @sapphi.red

you owe it to yourself to take a scroll through the quotes bsky.app/profile/lmao...

Man customizable select is sooo cool! Modern CSS is another level of powerful. svelte.dev/playground/8...

Dynamic CSS classes in Svelte is so elegant thanks to CLSX (since [email protected]) dynamic name + condition in array: ``` class={["badge", do_apply && `category-${selected}`]} ``` dynamic name + condition in object: ``` class={{ "badge": true, [`category-${selected}`]: do_apply }} ```

We released a svelte opencode plugin! Just adds `@sveltejs/opencode` to your plugin list in opencode to get: - The MCP server - The file editor subagent - An instruction file that tells the LLM to use the MCP server Configurable with a `svelte.json` in your opencode config folder! Check out! 🧡

We've released fixes for 5 CVEs affecting the Svelte ecosystem. Please upgrade your apps! Read the post to learn if you're affected: svelte.dev/blog/cves-af...

I did not realise that the documentation for Svelte @attach amounts to a whole page now! Wanted to do a quick skim and now I can’t stop exploring… svelte.dev/docs/svelte/... And ICYMI: day 3 of Advent of Svelte 2025 has a quick intro to attach by @kenthropic.com advent.sveltesociety.dev/2025/3

Using Svelte but undecided between SvelteKit vs Svelte + TanStack (or some other framework): Ben Davis produced a really solid video. 20 minutes is also short enough to share with management / watch with colleagues www.youtube.com/watch?v=1cGt... The chart lives here: lab.fubits.dev/svelteplot/s...

Happy New Year! Join us next Thursday, January 15, "Frameworks for humans in the age of machines" with Rich Harris - @rich-harris.dev PLEASE update your RSVPs if you cannot attend! RSVP: www.meetup.com/web-performa... This is a joint event with @sveltesociety.dev NYC #webperf #wpo #perfmatters

We released a Svelte Skill! It will teach your agent to use the svelte CLI to invoke the same tools as the MCP! We also released a subagent so that docs and iterations with the autofixer don't take up precious context! And you can get all of that easily because the repo is now a Marketplace! 🧡

Advent of Svelte 2025 was great 🎉 So many styles, so much diversity. Loved it 🧡 Have a nice end of the year See you next `pnpm i`

✅ Async Svelte / Remote Functions ✅ Drizzle + Realworld DB Usage ✅ Auth via Better Auth ✅ Svelte Kit APIs in depth www.youtube.com/watch?v=vkXx...

Christmas comes early this year

day 17 — Babbo Natale, sorry, I mean @paolo.ricciuti.me — is... eager to bring you a gift. if you've been nice, that is docs: svelte.dev/docs/svelte/...

days 15 and 16 (apologies for the brief disruption in service!) — • `command(...)` www.youtube.com/watch?v=DUM1... • optimistic updates www.youtube.com/watch?v=qUfK... combining all these, you can build type-safe, data-efficient apps that respond instantly docs here: svelte.dev/docs/kit/rem...

day 14: remote functions part three! today: the `prerender` function, which (unlike the existing prerender page config) lets you mix and match static and dynamic data docs: svelte.dev/docs/kit/rem...

day 13: remote functions part two, with @dummdidumm.bsky.social. today, a brief introduction to the best <form> handling you've seen in a framework docs: svelte.dev/docs/kit/rem...

Had a chitty chat with @kevinak.se @brittneypostma.bsky.social and @reinhold.is about Svelte Custom Renderers API...where we are at, how we approached building it and what it could unlock for svelte...check it out! 🧡

day 12: @dummdidumm.bsky.social brings us the first of several videos introducing remote functions, starting with `query`. expect to hear more about these in 2026! docs: svelte.dev/docs/kit/rem...

day 11: @jyc.dev — and his little helpers — take us on an adventure... using SvelteKit's `resolve` and `asset` to keep us safe from broken links - `resolve(...)` docs svelte.dev/docs/kit/$ap... - `asset(...)` docs svelte.dev/docs/kit/$ap... www.youtube.com/watch?v=Ekhb...

2/3 We (@peterkogo.bsky.social + me) have vague plans for the next meetup to happen in the 1st week of February. Join the guild if you don’t want to miss future events: guild.host/svelte-socie... Drop an email if you have feedback / want to help organise / give a talk / sponsor (svelte-berlin.de)!

Based on turnout (24), feedback, and the fact that most stayed till the end (despite us going over time) I dare to conclude that yesterday‘s Svelte Berlin Meetup was quite a success. We owe large chunks of that to @dominikg.dev who provided us with lots of time for Q&A and post-meetup chats 🙏 1/3

day 10: @kenthropic.com shows us how to make our unrefined code presentable to society, with `class` docs: svelte.dev/docs/svelte/...

day 9: ben davis is so enamoured of vitest that he might actually start writing tests docs: svelte.dev/docs/svelte/...

Advent of svelte 2025 is great. Love how unique and different the videos are. Thanks to everyone involved! advent.sveltesociety.dev/2025
