babel-preset-react-app with babel-preset-env

[matthewdordal]

I see that creat-react-app includes the babel-preset-react-app plugin for babel. Can I use this plugin with babel-preset-env or is that not necessary? I am not really sure what babel-preset-react-app includes.

It uses babel-preset-env.

It's unnecessary as we already include it 😄. Take a peek at the source to see what it includes as advised above!

Please note that if you're using CRA (react-scripts) configuring babel is unnecessary and will "just work" for any files in the src/ directory.

Is there a way to configure babel-preset-env when using it via the babel-preset-react-app package?

[miraage]

@djfdev atm it is only supported if you eject application.

@miraage doesn't babel-preset-env use browserslist so you could add the key to your package.json to configure?

"browserslist": ["> 1%", "IE 10"]
