Issues with React 19

[titouancreach]

What is the problem?

Hello, I have issue with using this package (React version with React 19).

Error: Cannot read properties of undefined (reading 'ReactCurrentDispatcher')
    at eval (viselect.mjs:250:15)
    at gr (viselect.mjs:661:4)
    at eval (viselect.mjs:663:26)

What is the current behavior?

The current behavior is that it throw with the exception I pasted above.

I've done some ressearch and it appears that is the problem when we use multiple React Version together.
So, I've copy/pasted the file SelectionArea.tsx directly into my project and installed vanilla package directly, and it worked ! (and that's ok for me).

I think a good way (and modern way) to distribute the React package should be to only transpile the tsx to jsx. I believe all people that use react have already a bundler and, the file would be build and run with the current version of React.

Anyway, it works and it does exactly what I was looking for thank you !

Please provide the steps to reproduce and create a CodeSandbox.

What is the expected behavior?

Your environment:

React 19 isn't released as stable yet.

I second this @AugustinasMK, I'm currently only building this against stable versions.

maybe we can anticipate a little bit and not wait for the user to complain to start to think to a fix
