react-jsx example no longer works when updating to React 18

[Morten Rand-Hendriksen]

Update the dependencies to React v18 and the react-jsx example no longer works. When the process runs, the generated page is blank and console returns the following error:

Uncaught SyntaxError: The requested module './../node_modules/react/index.js' does not provide an export named 'default' (at App.jsx:1:8)

Not sure if this issue originates with esbuild or modernweb-dev but it is not documented and is reproducible with any project running React v18.

Ran into a similar problem with the react-tsx example as well.

Had a minimal test case using https://github.com/modernweb-dev/example-projects/tree/master/react-tsx

1. Change the react and react dom dependencies in package.json to ^18.0.0.
2. Run npm install
3. Run npm run test
4. Get the following error:

🚧 Browser logs:
SyntaxError: The requested module './../node_modules/react/index.js' does not provide an export named 'default'

I found a CDN that provides an ES Build of react 18.2.

https://esm.sh/

By replacing the imports in every file the tests and demo ran in the react-tsx example.

import React from "https://esm.sh/react@18.2.0";
import ReactDOM from "https://esm.sh/react-dom@18.2.0/";

Useful as a demo, but maybe won't give Typescript support when importing via the cdn.
