Note that you’ll need to eject your config for this, which is a permanent action…Commands like
npm start and
npm run build will still work, but they will point to the copied scripts so you can tweak them. At this point, you’re on your own.
Note: this is a one-way operation. Once you
eject, you can’t go back!
