When I use npm start to view my app with local Port 3000, I am getting an error saying Port 3000 is already in use.

I checked to see if I had any windows opened using that app, but I don't. Is there a way to check to see what is running on that Port and how do I go about closing it?

Thank you for your help.

Try this - `netstat -an |find /i "listening"` – Kunal Mukherjee Jul 27 '20 at 05:07
run this command in terminal : `lsof -i:3000` – Saurabh Mistry Jul 27 '20 at 05:09
you can use `npx kill-port 3000` to kill the port – CodeBug Jul 27 '20 at 05:23
