First peek at Svelte 5 + NativeScript 🚀

Big thanks to @paolo.ricciuti.me, @svelte.dev, @syntax.fm and @mainmatter.com

Looks about right - really doesn't take much to do the first step. The fun starts when you want to convert the router/data loading :D

not an april fools joke: svelte is no longer just a web framework (or rather, won't be once we merge @paolo.ricciuti.me's magnum opus). have seen some extremely cool demos of this

Releases | TinyBase This is a reverse chronological list of the major TinyBase releases, with highlighted features.

Our final beta for the Svelte integration is out.

We made some breaking changes to the API to make it feel a little more idiomatic to Svelte, so please take a look and let us know if we got it right!

In an age of LLMs and streaming text, we need to stop trying to get markdown to play ball and restrict the syntax. I specced a stricter markdown sub(er)set several years ago and wondered if it was strict enough to support true streaming.

Turns out penguin flavoured markdown was ahead of its time.

Want!!!!!

Hey friends 👋

🎉 New *sv* version is out 🎉

We tuned the CLI help so:
→ humans get clearer commands & structure

This was surprisingly fun to test 😄

Give it a try and tell us how it goes!

How To Use Old Libraries Like P5.js In Svelte YouTube video by Joy of Code

I made a p5.js wrapper for Svelte you can install with `npm i @‎sveltecraft/p5-svelte` or watch the video where I explain how it's used and making old libraries work in Svelte

Modern CSS is just so awesome...all of this with view transitions!

Just merged a relatively significant set of changes to remote functions, especially `query`. It's fairly likely your next upgrade will break your app if you're doing anything decently advanced, but the errors should be pretty helpful/descriptive.

We will have a replacement/enhancement for that at some point in the future

Interesting - FWIW you can use the old syntax in Svelte 5, too. But it will be removed at some point in the future so if you're not comfortable with using tech in maintenance mode you'll have to switch at some point.
There's still enough time to do that though.

Broadly speaking yes.
It was one of the first really good routers built for Svelte, long before SvelteKit was a thing.

I got lucky with this library - the original maintainer happened to work at Vercel, too, so reaching out and getting trust to upgrade the repo was super easy. Will not be as easy for all of them, but I'll try my best!

Just released svelte-spa-router version 5, one of the bigger libraries that was still stuck on Svelte 4.

If that was your reason to not upgrade to Svelte 5, you can now.

What other libraries are blocking you from upgrading to Svelte 5?

I don't think Solid _can_ change here. It wants to treat async as invisible (you just invoke reads; type system says this is all synchronous values). Without a syntax hint (await) you cannot run async ahead of others

Rich and I just worked a combined 3 hours on a tricky bug.

AI quickly found out where it breaks and proposed a fix. But it was the wrong fix - we took the time to find out what was the underlying reason and fixed that instead.

Always think through what AI proposes to you.

This Week in Svelte, Ep. 134 — Changelog, convex-sveltekit YouTube video by Svelte Society

I'll make an appearance on This Week in Svelte, talking a bit about Convex and Svelte. See you there: www.youtube.com/watch?v=hHV7...

Community Session: Svelte on Vercel Learn more about Svelte on Vercel.

The summary is what I posted above😄no updates on timelines.

You can also rewatch it here: community.vercel.com/live/34169-c...

This was fun! We talked about
- Svelte's new async features
- SvelteKit remote functions
- How to get the best out of Svelte+AI (Elliott created a crazy potato canon website)

... and just had an all around great time with the community!

A lot of people have asked us "ok, I know the basics, but how do I write good, idiomatic Svelte code"? This best practices document gives you the answer. And if you're using AI, it's also installable as a skill.

Good your you, good for your agents.

The Vercel Svelte gang is live tomorrow - come say hi!

How we Rewrote 130K Lines from React to Svelte in Two Weeks We ported Strawberry's entire frontend from React to Svelte in two weeks using coding agents. It made the browser 2x faster.

myth: LLM-assisted coding means everyone is forced to use The Popular Framework forever

reality: agents will happily migrate your entire app to The Good Framework

inertia is a powerful drug but we are entering a world without moats, plan accordingly
