Problems with Node.js

#node #javascript #react

Hi,

I am wondering why my server side code only outputs "Hi ${port}" on console without (1) showing the actual port number or (2) opening up the "locolhost:5000" web page. My command is "npm start server." The screenshots of (1) the code and the (2) scripts part of the package.json file are attached. Thanks!

As others mentioned, use backtics in order to allow string interpolation.
And, regarding your server, it's indeed listening, but, it'll only respond to requests when you hit localhost:5000/api/sessions since you don't have a default handler for / route.

Because your "Hi ${port}" is a regular string which doesn't allow to paste variables there. You meant to use a template string.

Thanks! Besides, do you know from this code why locolhost:5000 did not load though?

The server handles only "/api/sessions" route, not the "/" you are trying to access by opening localhost:5000. You should add the handler for that too.
