Serfu

The start of something memorable.

Utilities

useServerRef

You need local memory in your server functions that is stable across the ssr and server-functions Vinxi routers? useServerRef can be used inside server functions to create and access local memory. This follows similar rules like React Hooks:

• You can call it multiple times, every call returns a different memory location
• You should not change the order of the calls at runtime
• You should not call useServerRef in a condition

Usage

import { useServerRef } from "serfu";

const count = async () => {
  "use server"
  const value = useServerRef(0);
  value.current++;
  return value.current;
};

Use Cases

• ✅ Store local, unnamed state related to a server function
• ✅ Memoize expensive server function logic
• ✅ Cache server function results
• ⛔️ Store global, named state, that can be accessed from multiple places on the server
  • Use Unstorage or a DB of your choice instead
