回答1:
You are missing the command in your package.json in the scripts part.
Add this start line to that:
...
"scripts": {
"start": "node server.js",
"test": "jest",
...
Or anything else you use to start your application.
NOTE: in your package.json you have a main script defined as index.js and you posted a file server.js that looks like the main entry point. Maybe its intentional, but I use to have them the same.
