Make import of ReactDOMServer work with React 18

[fsoikin]

Importing react-dom/server.js works with React 16 and 17, but for some reason fails with React 18. esbuild reports that "react-dom does not export server.js".

Hi @fsoikin, any news?

Just brainstorming for the error cause:

• Could the error come from the fact that React 18 is incompatible with React 17 and in build.yml we have versions below 18?

  build:
    strategy:
      matrix:
        react-version: [16, 17, 18]

• By the way is there a typo (missing t) in the esbuild error message you reported?

esbuild reports that "reac-dom does not export server.js".

No, I haven't had much time to work on this one. It's not required for my current day job, so I can't justify spending too much effort.

React 18 is sure incompatible with 17, but I don't see how that makes any difference here. We're not trying to use them side by side, only swap one for the other.

React 18 seems to have a slightly different module organization, which doesn't allow the same code to import both server-side and client-side modules, but I haven't really investigated in depth.

If you have any ideas and free time, feel free to try this yourself, I will very much appreciate a contribution.

(and yes, that's a typo; fixed; but it's not the exact error message, I was just paraphrasing anyway)
