Your error is EADDRINUSE 127.0.0.1:8000 . Or in other words - ERROR: ADDRESS IN USE 127.0.0.1:8000 . Meaning, something is already listening on port 8000.

Make sure you aren't trying to run npm start multiple times. Or you can use netstat -ab in an Administrative Command Prompt, to see what is listening on that port and kill the process or change the port of your node server.
