How should I configure the shared module when using module federation for micro frontend

[NearImba]

I'm using Svelte5 and vite. For svelte4 I tried svelte and svelte/internal and it works. But it's broken in svelte5

The lesson to learn: Never depend on undocumented stuff (svelte/internal).

This topic interests me (micro-frontends). I do them using single-spa, though. Can you describe in detail what "broken" means? Add error messages, descriptions of behaviors, etc. Just saying "broken" is not helpful, and probably why nobody has answered you.

I am also trying to get module federation to work with svelte 5 but without any luck. I get the same error as when I tried with webpack. See more in this issue: #13186

I believe this comment pinpoints the issue quite well and I am afraid that it is not possible at this time with svelte 5: #13186 (comment)

Crossing my fingers that this becomes possible 1 day with vite module federation :)

I see. For anyone's benefit, it is 100% possible to create MFE's using single-spa. I had to create the Vite plug-in for this library (vite-plugin-single-spa, which works for any framework), and a version of the Svelte adapter for v5 (@wjfe/single-spa-svelte).

In my opinion, single-spa is superb because it is simple and fully agnostic. If module federation doesn't work, try this route. I know, not exactly the same thing. If it works for you, great.
