Coming from Developer Summit, @Lindsaykwardell was mentioning from Vue v3.2 release notes on SSR improvements:

The @vue/server-renderer package in 3.2 now ships an ES module build which is also decoupled from Node.js built-ins. This makes it possible to bundle and leverage @vue/server-renderer for use inside non-Node.js runtimes such as CloudFlare Workers or Service Workers.

We also improved the streaming render APIs, with new methods for rendering to the Web Streams API. Check out the documentation of @vue/server-renderer for more details.
