How do you create server-only files?

[fleet herald]

In SvelteKit, modules inside server folders or those with .server.ts extension can only be imported by other server modules. Trying to import such files in files that could run on the client will result in an error.

I know server functions exist, but I want make sure files that contain Drizzle table schemas, for example, cannot be imported on the client. Or am I thinking about this wrong?

Is there a way to achieve something similar in Start?

I'm not looking to define a function.

I want make sure modules that export Drizzle table schemas cannot be accidentally leaked on the client.

does this mean I have to wrap everything inside functions?

i usually just wrap my db instance in that

but for whole files i guess you could use https://www.npmjs.com/package/vite-env-only

You can make it an IIFE though
