Why will this site not come up?

Here's what my console says:

$ npm start

So, I'm on my browser, I type in http://localhost:4040 and...

This site can’t be reachedlocalhost refused to connect.
Try:

Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED

Is there anything that I'm missing?

Does the content from my console explain why my site won't even come up?  Am I on the wrong port?

Why can i not see the site?
