Answer 1

Error: listen EADDRINUSE to solve it in Ubuntu run in terminal netstat -nptl and after this kill -9 {process-number} this command is to kill node process and now you can try to run again node server.js command

Ex

listen EADDRINUSE :::8080

netstat -nptl

tcp6 0 0 :::9000 :::* LISTEN 9660/java
tcp6 0 0 :::5800 :::* LISTEN -
tcp6 0 0 :::5900 :::* LISTEN -
tcp6 0 0 :::8080 :::* LISTEN 10401/node
tcp6 0 0 :::20080 :::* LISTEN 9660/java
tcp6 0 0 :::80 :::* LISTEN -
tcp6 0 0 :::22 :::* LISTEN -
tcp6 0 0 :::10137 :::* LISTEN 9660/java

kill -9 10401
