I included the react-input-colorpicker package and imported it in the component.
When compiling, it gives an error:

You may need an appropriate loader to handle this file type.

Like, an appropriate bootloader is required, hmm - tell me, please, what is it?
Thank you!

Answer 1

In theory, in https://github.com/homfen/react-colorpicker/blob/m... spread object operator
and because of

loader: 'babel-loader',
include: [
  path.resolve(__dirname, './src'),
]

babel does not apply to files in node_modules.
