Compile Error with Create React App with React 17

[tioluwani94]

Hello 👋🏽,

I'm getting a compile error when I try to use the react-resizable-panels components in my project:

I have the following setup in my package.json:

"react": "17.0.0", "react-dom": "17.0.0", "react-scripts": "4.0.3",

I'll appreciate any pointers to resolve this, thank you!

The operator causing the error you're reporting is the nullish coalescing operator (??):

return state[key] ?? null;

Guessing create-react-app isn't configured to handle that. I don't know what the easiest fix is. I'm not a create-react-app user anymore.

Hi, @bvaughn thanks for the response it was very helpful. I was able to resolve the issue with the help of this:
facebook/create-react-app#9468 (comment)

Glad to hear it!

FYI, I removed the nullish coalescing operator in v0.0.31 because the trivial benefit it provided didn't seem worth causing headaches for create-react-app users.

Alright, thanks for the update.

By the way, if you update to 0.0.35– this module should now work with CRA without any additional configuration changes.
