Named exports not present after build

[nojaf]

After a build I'm getting Uncaught SyntaxError: The requested module '../web_modules/react.js' does not provide an export named 'useEffect'.

This can be reproduced if the code has a mix of import styles.

import React, { useState, useEffect } from 'react';
import * as react from 'react';

See repo for full bug reproduction.
Adding namedExports to the snowpack config does not change the situation.

Thanks for filing. Does the issue away if you remove import * as react from 'react';?

Rollup just released a big CJS update, and since rollup powers our internal install logic that may fix this. If that doesn't work, then we can see if the issue is on our end.

Yes, the issue does not occur when I remove the import * as react from 'react' part.
Problem is that a third party library is using this and it is outside of my control.

Still a problem with the 1.8 release.

Okay, thanks! I'll spin up a prioritized issue to track. Would love any help if you're interested in triaging to find out what's going on inside of Snowpack/Rollup to cause this bug.

Yeah, if you can give me some pointers I could take a look sometime.

I just did some digging and think I found the issue! Creating a PR now

Fixed in #879!

Many thanks!
