Answer 1

Use this to install react and react-dom:

yarn add react react-dom

If this not work, you You have to fix the 'externals' configuration in webpack.config:

externals: {
   'react': 'react',
   'react-dom': 'react-dom'
} 

Answer 2

I think in many cases people will already have react-dom. If so, based on the comments, I think it is worth checking if you have added @hot-loader/react-dom as an alias, but forgot to install it. In such cases you need to do:

npm install -D @hot-loader/react-dom
