build: worker throws with Uncaught ReferenceError: window is not defined (anothor issue to fix)

In my case, the above error is resolved by build.rollupOptions.output.manualChunks.

// vite.config.js
import { defineConfig } from 'vite';
const prefix = `monaco-editor/esm/vs`;
export default defineConfig({
  build: {
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: [`${prefix}/language/json/json.worker`],
          cssWorker: [`${prefix}/language/css/css.worker`],
          htmlWorker: [`${prefix}/language/html/html.worker`],
          tsWorker: [`${prefix}/language/typescript/ts.worker`],
          editorWorker: [`${prefix}/editor/editor.worker`],
        },
      },
    },
  },
});
