title	getServerFunctionMeta

getServerFunctionMeta returns a function-specific id string, that is stable across all instances when server functions are run in parallel on multiple CPU cores or workers.

This id property can and will change between builds.

import { getServerFunctionMeta } from "@solidjs/start/server";

// or some in-memory db
const appCache: any = globalThis;

const counter = async () => {
	"use server";
	const { id } = getServerFunctionMeta()!;
	const key = `counter_${id}`;
	appCache[key] = appCache[key] ?? 0;
	appCache[key]++;

	return appCache[key] as number;
};

Parameters

getServerFunctionMeta(): { id: string }
