katanakit-js / useRunStorageScope

Function: useRunStorageScope()

function useRunStorageScope<T>(fn): Promise<T>;

Defined in: src/infrastructure/storage/storage.service.ts:327

Runs fn with request-isolated in-memory storage (SSR). Use this around a request handler so useSetStorage / useGetStorage share state within the request but not across requests.

In browser environments, this simply calls fn() directly (no ALS needed).

Type Parameters

Type Parameter	Description
T	Return type of fn.

Parameters

Parameter	Type	Description
fn	() => T | Promise<T>	The function to run within the storage scope.

Returns

Promise<T>

The return value of fn.

Example

import { useRunStorageScope, useSetStorage, useGetStorage } from "katanakit-js";

export default defineEventHandler((event) => {
  return useRunStorageScope(() => {
    useSetStorage("req-id", event.context.id);
    return useGetStorage("req-id");
  });
});
