Is there anyway to ensure I don't accidentally leak content from a server only file to the client?

Sveltekit has this feature https://svelte.dev/docs/kit/server-only-modules to prevent secret leaks. I am wondering if there is anything similar for start. Or is the solution to just be really careful?

Is serverOnly and clientOnly only for functions? Say I have a auth client exported in a file:

export const auth = betterAuth({
    emailAndPassword: {    
        enabled: true
    } 
})

export const auth = betterAuth({
    emailAndPassword: {    
        enabled: true
    } 
})

Is there a way to prevent this being importable on client?

Yep functions only. You can make it like this:

export const auth = serverOnly(() => betterAuth({
    emailAndPassword: {    
        enabled: true
    } 
}))()

export const auth = serverOnly(() => betterAuth({
    emailAndPassword: {    
        enabled: true
    } 
}))()

hmm, more inconvenient than "use server" or "server/" module but I guess this works
