Bundle web workers that work in nodejs and the browser, without a separate build target.
npm i -D rollup-plugin-worker-factory
--experimental-workersinclude rollup-plugin-worker-factory in your rollup plugins array for a build:
const worker = require('rollup-plugin-worker-factory'); ... plugins: [ worker() ] ...
When you want to include a worker in your code prefix the file with worker!:
import SomeWorker from "worker!./src/some-worker.js";
Your worker should run without exporting any code and use the global self variable to interact with the worker API. worker_threads.parentPort for node has been slightly modified so that their API more closely matches web workers in the browser and will also be available on the global self.
const someDependency = require('../some-dep'); const whoKnows = require('who-knows'); self.addEventListener('message', function(e) { const foo = someDependency(e); self.postMessage(whoKnows(foo)); });

Default: 'universal'
The type of factory to build, can be 'node', 'mock', 'browser', or 'universal'.
browser will only work in the browser
node will only work in node
mock will work everywhere but runs on the same thread
universal will work on the browser or node depending on available apis
