Summary

We introduced the UMD build https://mui.com/material-ui/getting-started/installation/#cdn to allow developers to easily play around with Material UI's API. This was pre-CodeSandbox/StackBlitz era. Almost 10 years ago.

Nowadays, we can use ESM CDNs

To configure emotion, developers would need to use the external feature of esm https://esm.sh/#docs

Hey @oliviertassinari, I tried your codepen but the button is not showing, do you know why that might be?

React is removing its UMD build: https://react.dev/blog/2024/04/25/react-19-upgrade-guide#umd-builds-removed.

@DiegoAndai The error in the console is:
SCR-20240504-ciei

So the first thing you want to do is disable source map, source maps are a huge mess for debugging this type of problem. Once done, it becomes a lot more clear:

SCR-20240504-ciot

The problem is that it loads different versions of React.

The solution is to enforce the same version. The docs https://esm.sh/#docs explain how. First, I have tried to use ?deps=react but it's broken, it doesn't propagate this to dependencies of dependencies. So instead, I'm relying on import maps; also documented there with ?externals.
Example updated, it works now.
