Alright, since HN is doing its tedious grumpy-old-man thing, let me just spell this out: Your old Svelte components will continue to work. There'll be some 'breaking changes' in the persnickety semantic versioning sense, but migration will be smooth. It's a big priority for us.

But the thing you'll be able to easily and incrementally migrate _to_? It's radical.

I'll get off your lawn now.

Big thanks for all the work you've done: I've been using SvelteKit mainly for experimentation & one-offs.

Svelte v3 -> v4 migrations have so far been a breeze for me: An entry update to package.json and an 'npm update' is all I need to do to migrate, and I've been doing basic CRUD & SSR/CSR SVG renders in my test projects.

I have no clue what kind of esoteric state management / render manipulations everyone else has been doing to make Svelte angry.

Thanks for the re-assurance. We've been migrating a huge app to svelte over the last 6 months and it's nice to hear it won't be become legacy on arrival ;)

Looking forward to the easy & incremental paradigm shift whatever it is.

I'm hoping there could be some improvements to composability and slot edge-case usage possibly?

Hey Rich,

Will Svelte or Sveltekit get incremental builds like NextJS?

As swyx said, it's probably not a priority for us. You can basically get the same benefits by using Incremental Static Regeneration, which is turnkey if you're using Vercel (not through any tight framework<->platform integration, but rather because the platform offers the feature and the Vercel adapter exposes it — any other platform could do the same thing): https://kit.svelte.dev/docs/adapter-vercel#incremental-stati...

(am not rich, just giving thoughts on why i disagree with the premise of the question) incremental build is a static site concern and i think its pretty clear the industry has more or less given up on that as a scaling strategy for websites in favor of serverless/edge rendering (which you can blend with static generation to get almost the same thing as incremental builds)
