If you are using paths and the project it’s getting bigger you might want to consider using absolute paths:
.env
src/
components
├── App.js
App.test.js => import App from '../App';
create a .env file under the root directory of your node app: NODE_PATH=src/
App.test.js => import App from 'components/App';
This way you’ll not have to worry again about ugly paths and you can move files within src folder freerly.
