Server functions

Mark a function "use server" and its body runs only on the server. The compiler strips it from the client bundle and replaces the call with a typed RPC — so secrets and database access never reach the browser.

async function getUser(id: string) {
  "use server";
  return db.users.find(id); // runs on the server
}

// call it anywhere like a normal async function:
const user = await getUser("42"); // POSTs to /_server under the hood

Request context

Inside a server function you can reach the current request — headers, cookies, the URL:

import { getRequestEvent } from '@fluixi/server';

async function whoAmI() {
  "use server";
  const event = getRequestEvent();
  return event?.request.headers.get('authorization');
}

Form actions

@fluixi/forms turns a server function into a progressive-enhancement <form action>, so it works before JavaScript loads.
