Marking this as draft because different thought just occured to me:

• What if we add the ambient typings to the@types namespace? Would this be something we should do in the long run anyway?
• Is this solvable by adding another reference to theapp.d.ts (/// <reference types="svelte2tsx/svelte-jsx" />,@rgossiaux does this work for you?) template in the case of SvelteKit?

From what I see theapp.d.ts is not passed to emitDts, since it lives outside thelib/ directory, so you'd still need a config change to solve that. But regardless, anything that solves the problem works for me, I'm not picky 😃

Oh right you're correct, that wouldn't work for you in this case. You could add ad.ts file to the lib folder with the mentioned content and exclude it from being exported, maybe that works.

Wondering if there was any movement on this, or did you end up solving this in a different way?

FWIW, I'm working on a Svelte component library, and we're compiling the Svelte components to web-components. We're usingsvelte2tsx to generate the type definitions which we use to get intellisense & typings in a React wrapper. This works really well for most cases, but when the component is something primitive (like a button or a link) and we want to expose the props on the underlying HTML elementsvelte2tsx breaks.

Currently, I have a fork ofsvelte2tsx with this change, which I'm vendoring into the repository and it works really nicely. Any chance we could land this? It solves this really nicely 😄

The plan is to move the element typing to the svelte core. You can see the roadmap here#1552

Okay, got this working without thesvelte2tsx fork by bumping Svelte to 3.55.0 and usingSvelteHTMLElements['button'] instead of thesvelte2tsx typings. Thanks@jasonlyu123!

Since Svelte 3.55 it's possible to enhance from HTML typings through thesvelte/elements import. I think this PR might be obsolete because of this.
