@lazarv/react-server/worker

Helpers for modules marked with the "use worker" directive. On the server runs in a Node Worker Thread; on the client runs in a Web Worker.

function isWorker(): boolean;

Returns true when the calling code is executing inside a worker spawned by a "use worker" module.

• Server — checks whether the current Node.js thread is a framework-managed Worker Thread. Returns false in Edge builds where "use worker" functions run in-process.
• Client — checks whether the current context is a Web Worker.

Works identically in both server-side and client-side "use worker" modules. Import from @lazarv/react-server/worker — this sub-path has no server-only dependencies and is safe to use in Web Workers.

Returns — true if inside a "use worker" worker, false otherwise.

"use worker";

import { isWorker } from "@lazarv/react-server/worker";

export async function terminate() {
  if (isWorker()) {
    process.exit(0);
  }
}
