Vite SSR with non nodejs backend

[Writtscher]

Hi I have a question. I am migrating away from a webpack build to vite. For the client part everything works fine just the backend is a bit more complicated. We have a JVM Backend (design reason) and would like to prerender our frontend code. We have something like

import React from 'react';
import ReactDOMServer from 'react-dom/server';
import { StaticRouter } from 'react-router-dom';
...
import App from './views/App';
...

function renderToString(url, context, locale) {
  return ReactDOMServer.renderToString(
    <StaticRouter>
       <App/>
     </StaticRouter>
   </LocaleProvider>
  );
};

Now webpack bundles it into one single file to use this script to prerender our frontend.

With vite I have not found anything to make this work. I would like to avoid having a hybrid where vite bundles/builds our frontend part and webpack to bundle/build the same code differently for the backend part.

I tried a lot of configuration options with the --ssr Flag but no luck.. Can someone point me in the right direction?
