How do I debug a Node.js server application?

Right now I\'m mostly using alert debugging with print statements like this:

Answer 1

Using Chrome Version 67.0.3396.62(+)

1. Run node app

node --inspect-brk=0.0.0.0:9229 server.js(server js filename)

2. Browse your app in chrome e.g. "localhost:port"
3. Open DevTools.
4. Click the the node icon beside the responsive device icon.

There will be another DevTools window that will pop out specifically for debugging node app.
