vite-node-worker

Import Node.js workers with ?nodeWorker in Vite. HMR support in dev, separate chunks in build.

An updated version of https://github.com/alex8088/electron-vite/blob/master/src/plugins/worker.ts with support for dev, not just build.

npm install vite-node-worker

Usage

// tsconfig.json
{
  "compilerOptions": {
    "types": ["node", "vite-node-worker/types"],
  },
}

// vite.config.ts
import { nodeWorker } from "vite-node-worker";

export default defineConfig({
  plugins: [nodeWorker()],
});

// worker.ts
import { parentPort } from "node:worker_threads";
parentPort?.on("message", (data) => {
  parentPort?.postMessage(`Processed: ${data}`);
});

// main.ts
import Worker from "./worker?nodeWorker";
const worker = new Worker();
worker.postMessage("data");
worker.on("message", console.log);

Standard Node.js Worker constructor minus the script source. TypeScript support included.
