import { type Snippet } from "svelte"; let { children }: { children: Snippet } = $props() is such a catastrophic downgrade from <slot/> when you just want to write a simple component that wraps other stuff. Yeah, <slot/> is still available, but Svelte will shout at you once you start using runes. - ThreadSky

This is a good point. Although for me personally, the way props have to be typed is the larger issue here. But other than that I'm really Happy with the changes overall.

I feel like an exported props type should be a first-class citizen of .svelte components that automatically types $props. Kinda like

```

Foo is {$props.foo}, and bar is {$props.bar}!
```

I can only dream =)

(not sure if this is feasible, and it would certainly not be backwards compatible. I'm just doodling)

That would be a nice addition indeed. It certainly had its weaknesses, but

export let foo: string;

was very ergonomic for declaring and typing props. Nowadays adding types to props feels like Like deadweight in a way.

This is exactly how you typed props with particular type requirements in svelte for...well not exactly you just needed to define a type or an interface named `$$Props`...but I suspect this was removed in svelte 5

I remember using it a couple of times when I had to have generic types in my components. But I didn't use it in other ways.

I've never used it but now I want it back! :-p

I think to a large extent this is more an issue with the tooling than with Svelte itself. I can probably fix all these grievances with some custom code snippets (ha).

In summary, even with these minor gripes, I freaking love working with Svelte 5 and SvelteKit. The speed at which we're iterating on our apps and components is just incredible, performance and bundle sizes are top tier. Absolutely love love love the stuff.
