    This means there's already a program or service utilizing port 3000. Either change ports or terminate the process on port 3000. If you need help finding the program/service, refer to [this](https://stackoverflow.com/questions/48198/how-can-you-find-out-which-process-is-listening-on-a-port-on-windows) question – gabriel.hayes Oct 22 '19 at 19:48

Might be you are trying to create a server twice in the same project. (happened to me ;-)) or another project is using this port.

my advice is to simply change the port number and restart nodejs.
