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 😄

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.

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!

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.

We released a new version of the svelte opencode plugin. It now ships with all the available skills and automatically adds them to your opencode skills (require last version of both)
If you want you can disable the MCP or the Skill by creating a `svelte.json` next to your `opencode.json` config 🧡

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.

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,

Configurable with a `svelte.json` in your opencode config folder!
Check out! 🧡

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! 🧡
