Bundle Components into 1 File

Describe the problem

• I have a route that is getting a lot of traffic.
• That route uses many components and when compiled each of these components get compiled into 1 file each.
• I use vercel to deploy my projects and vercel caches automatically on the edge network.
• A lot of traffic + A lot of components = A huge bill
• I can solve it hardcoding every component into my +page.svelte but clearly I don't want to do that.

For reference using Svelte 5 + SvelteKit.

Describe the proposed solution

I would need a way to compile every component into 1 file and if it is called from /+page.svelte with a lot of traffic use that big file. Or maybe even some docs on how to compile svelte into ES Module (I have found some, but they are all using rollup or really old versions of svelte). None of them uses sveltekit.

WebComponents are simply nasty and I don't want to deal with them. (Unless you tell me that they are the only way I won't use them).

Importance

i cannot use svelte without it

Start with the reported Svelte 5 + SvelteKit route and its +page.svelte entry point, then inspect the generated component files for a high-traffic route. Clarify whether the requested outcome is a SvelteKit bundling feature or documentation for an existing ES module workflow. Done would require a decided scope and a reproducible, supported approach for controlling the generated output.
