Hey Eugene — this article has saved me hours and hours of potential headaches on two occasions, so thank you so much for putting it togehter.

Newbie question. I’m able to deploy it and run it Heroku, but I’m unable to get it to work on my local machine now. Should I be using npm start (I used npm instead of yarn) or should I be using node ./src/server/index.js to start? When I use the former, the app launches, but the server doesn’t. When I use the latter, terminal just spins forever.

Any ideas would be appreciated!
