Is there such a thing as internal functions? Something that can only be called from Tanstack start functions.

I've just created a system for sending notifications, which will only ever be consumed in server funcitons, so I'm wondering if there's a solution to ensure that sending notifications can only happen from server functions.

Specifically "server functions" i believe no.

There is one for "executeable only on server side" though, serverOnly

import { serverOnly } from '@tanstack/react-start'

const thisCanOnlyBeExecutedOnServerSide = serverOnly(() => {
  // ... implementation
})

it will throw if called from client side

Hell yeah, thanks for that! Worked a treat

#

I was looking through the docs for server only, so maybe I just blind on that day
