resolve external dependencies

[elyobo]

import { green, orange, red } from '@mui/material/colors'

We have imports like the above, which would ideally resolve to @mui/material/colors/index.js whether setting bundle to true or false, however the import is not transformed in either case leading to breakage downstream (as MUI doesn't ship proper exports config in their packages as of v6, potentially being resolved in v7).

Hi @elyobo, thanks for raising your issue!

You're right that MUI (as of v6) doesn't ship proper exports configuration in package.json, which leads to resolution issues when importing. And you're right, this package do not alter external dependencies as bundle: false in the stup config.

Implementing this feature could be dangerous and might break other dependencies resolution.

A safer approach would be to implement a separate plugin that specifically handles cases where a package lacks proper exports but relies on conventional folder structures (like @mui/material/colors/index.js).

If you’re interested in contributing this as a separate plugin within the repo, I’d be happy to discuss further! Let me know what you think.
