node-sass v5.0.0 compilation error

Describe the bug

Installing node-sass as recommended in the documentation to have SASS support returns following error on compilation:

Error: Node Sass version 5.0.0 is incompatible with ^4.0.0

sass-loader was updated to v10.0.5 for supporting node-sass v5.0.0 (https://github.com/webpack-contrib/sass-loader/pull/899), but react-scripts is pinned to sass-loader 8.0.0. This means that every fresh installation (or update) which is using node-sass will end up with this error on yarn/npm start.

Reproducible demo

It might be a good time to move to sass (dart implementation) instead of libsass/node-sass.

Further to the above, also note that node-sass has been deprecated.

I followed this suggestion and simply replaced node-sass with sass and everything seems to be working fine without any other changes required.

npm uninstall node-sass
npm i sass
