Looks like the import map for react-dom/server (https://ga.jspm.io/npm:[email protected]/server.browser.js) returns this JS:

import"react";import"object-assign";export{default}from"./cjs/react-dom-server.browser.production.min.js";

I'll investigate.

The import map generator allows you to use either a "production" or "development" version of the dependencies. For our import maps, the mode only affects the react libraries. Previously, we were on the 'production' version. The last commit switches to the 'development' version. Since the development version uses non-minified JS code, identifiers like createRoot still exist rather than being minified to something like e.

With the latest commit, the ButtonReactHooks example now works:

I wonder, does bumping the version also fix this? I would think this might need to be in sync with the purescript-react purescript-react-basic libraries which were recently updated to 18 (I'm actually surprised that createRoot is in the dev version of 16.13.1).

[JordanMartinez]

Looks like you're right. Bumping the React version to 17.0.2, the last release before 18, makes it work.
