vite-plugin-worker-proxy

Workers have a cross-origin policy that prevents them from being imported from a different origin. This plugin allows to import workers from a different origin by proxying the worker script with a Blob url.

Generally, this plugin is useful only in development mode, since in production the worker script should be served from the same origin.
