9,415 PointsI had the same issue and here is my solution for the problem:
When you open for example Chrome Dev Tools, you really can't see what you logged into your console, but you can download React Developer Tools extension for Google Chrome/Mozilla Firefox(it's basically something like Vue Devtools for Vue) on GitHub .
Once you refresh the page, you can see what you logged into your console.
Hope this helped.

Do we need to download a package like nodemon for Python's http server to update?

I was having the same problem until I realized I hadn't saved yet, then I refreshed the page and app.js appeared under Sources in the Chrome DevTools.
