Server seperation

We can use createServerFn to create functions which are callable but not directly part of the client bundle (as far as I understand). How do we create server side functions which are NOT callable by the client? For server side utilities and common functionality.

You should be able to split correctly, but if you wanna be super sure you might include a vite plugin called vite-env-only and have it configured like this: 
 denyImports({
        client: {
          specifiers: [
            "fs",
            /^node:/,
            "drizzle-orm",
            "postgres",
            "node-ray",
            "Buffer",
            "process",
            "path",
            "os",
            "url",
            "crypto",
            "stream",
          ],
          files: [
            "**/.server/*",
            "**/*.server.*",
            "src/console/*",
            "src/services/(?!.*types).*",
          ],
        },
      }),
 denyImports({
        client: {
          specifiers: [
            "fs",
            /^node:/,
            "drizzle-orm",
            "postgres",
            "node-ray",
            "Buffer",
            "process",
            "path",
            "os",
            "url",
            "crypto",
            "stream",
          ],
          files: [
            "**/.server/*",
            "**/*.server.*",
            "src/console/*",
            "src/services/(?!.*types).*",
          ],
        },
      }),

Hey, thanks for suggestion! Will look into plugin and config.

Your welcome, in this example it will deny importing to client those imports + the folders / files i mentioned there. like anything from services except the types, so this give me confidence that nothing on the services ( business logic ) should ever leak into the client
