It *might* have to do with lit re-exporting directives from lit-html as a transitive implicit dep. AFAICT would still be a bug of the vite plugin if it cannot handle that, so nothing wrong about it from lit perspective I think. Just a symptom of sharing not working correctly.

Simon Ihmig @simonihmig.bsky.social · 09/04/2026

No, you can explicitly declare shared deps to be treated as singletons. However, that was not working for me as described in this issue: github.com/module-feder... Which brought up the issue of lit in dev mode and lit-html in prod clashing, as the latter was not properly shared for some reason.

And how you compose the two worlds together is a legit framework design choice. I can't see why JS-in-HTML should be semantically or logically better than HTML-in-JS tbh.

000

Simon Ihmig @simonihmig.bsky.social · 30/03/2025

All of Svelte is a superset of HTML, or just the templating part? I would say the latter? I am all for the template to be a superset of HTML (don't like JSX), but you need JS at least to glue things together. Most likely your app will host way more JS than HTML though.

Simon Ihmig @simonihmig.bsky.social · 30/03/2025

Interesting to see that us coming from a similar/same background, we also stumble over the same issues! 😅 Nice write-up!

020

Simon Ihmig @simonihmig.bsky.social · 30/03/2025

That wasn't my point though. Yes, you can define features like runes in tests, except for the most basic feature: components. You can't invoke the component under test in the way you would normally do. Also can't define components locally in your test to pass to higher order components.

000

Simon Ihmig @simonihmig.bsky.social · 30/03/2025

Not trying to hate on Svelte, I like it quite a bit! But I do feel they got this template vs. JS thing backwards.

120

Simon Ihmig @simonihmig.bsky.social · 30/03/2025

Besides the snipped argument, you see the limitations of "js inside template" also for tests. You need to pass props to the render function, invoking the component in a totally different way than you would do in app code. Just because you cannot have template code inside JS.

220

Simon Ihmig @simonihmig.bsky.social · 30/03/2025

I think modern Ember nailed it. Instead of .svelte being a template with an island of JS, Ember's .gjs is JS with an island of template. Or multiple. <template> is just a value, that you can direcly use when in scope (private internal components) or you export it. guides.emberjs.com/release/comp...

Simon Ihmig @simonihmig.bsky.social · 30/03/2025

First time learning about snippets I was thinking this must be a workaround due to some architectural flaw/restriction. Why do you need the concept of "snippet", if you already have one of "component"? Only because Svelte syntactically doesn't allow you to define components inside components, right?

Ever heard of ThumbHash? It's a great way to encode a blurry placeholder image into just a few bytes, 28 here. Like BlurHash but better visual quality! Available now in responsive-image.dev for @vite.dev or webpack plugins and image components for @emberjs.com @lit.dev @solidjs.com and @svelte.dev!

Good question! Unpic does not have its own image processing capabilities, it requires an image CDN. ResponsiveImage supports that, too (tho not all CDNs yet), but also processing local images in your repo, with its vite and webpack plugins. That's the main differentiator I think.

I have a nice example for exactly that: ember-responsive-image provided both build-time and runtime aspects in a single v1 addon, but heavily tied into the 🥦 legacy build system. Nowadays the build part is a framework-agnostic @vite.dev or webpack plugin, and the component a light-weight v2 addon.
