1. Initialize project using Create React App

$ npx create-react-app cra-to-nx-bugs --template typescript
$ yarn start

✅ it works

2. Convert project to nx workspace

$ npx cra-to-nx
$ yarn start

❌ it doesn't work:

yarn run v1.22.10
$ nx serve

> nx run cra-to-nx-bugs:serve
C:\Repos\cra-to-nx-bugs\node_modules\.bin\react-app-rewired:2
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
          ^^^^^^^

3. Fix issues

First, calls to react-app-rewired binaries must be changed in workspace.json:

Second, .env contains unnecessary double quotes.

Now try to run it:

$ yarn start

✅ it works again

Additionaly nx is making a change to tsconfig.json:

The following changes are being made to your tsconfig.json file:
  - compilerOptions.jsx must be react-jsx (to support the new JSX transform in React 17)
  - compilerOptions.paths must not be set (aliased imports are not supported)
