You probably already have a node application open at port 8080.

Try changing your port.

You can check if the PORT number is available by using the command:

netstat -tulnp | grep <port no>

or you can use lsof:

lsof -i :<port no>

You are using restricted port source

try using port 3000

EDIT: You CAN run on a restricted port if you have admin rights
