Currently not possible due to lack of support of non-typescript files by JSR:

error: Expected a JavaScript or TypeScript module, but identified a Unknown module. Importing these types of modules is currently not supported.

I was able to publish ReactionButton.svelte to JSR but it is impossible to import it because it's not in package.json exports field. If I add it as export to jsr.json, JSR refuses to publish the package. Even if I manage to find a workaround, it seems JSR automatically transpiles all files to JavaScript after publishing, so I doubt Svelte will work with that. So far I have only found a single Svelte project published to JSR but the author included the Svelte itself into the bundle which caused its size to be over 3 MB.
