getting an error- listen EADDRINUSE :::3000 on windows machine

Question

I've searched a lot and I understand there is some process or server running on port 3000, but how can I stop that and run a new express http server on port 3000. There are few answers which tell it for Unix environment..but how to release the port on windows environment using cmd terminal. Closing the task using PID also didn't work for me. Thanks in advance

Open the command prompt and type the following

netstat -a -o -n

run down the list by port until you find port 3000 and you will see the process id. Then run

taskkill /F /PID (yourprocessID)

there's another simple way to do this in a single command

FOR /F "tokens=4 delims= " %%P IN ('netstat -a -n -o ^| findstr :3000') DO TaskKill.exe /PID %%P

if you use windows 7 U might need tokens=5, use with caution tokens are different for different OS.

This worked perfectly, thank you for the guide @Gnanesh – torbenrudgaard Jul 02 '17 at 23:45
I was able to 'netstat -a -o -n' to determine the PID but the taskkill errored out because of '/F' flag. – user752746 Nov 17 '17 at 03:15
I found this http://tweaks.com/windows/39559/kill-processes-from-command-prompt/ article that was very helpful. – user752746 Nov 17 '17 at 03:41
@user752746 - try this on command prompt: taskkill /pid PIDNO /f https://stackoverflow.com/questions/8553957/how-to-release-localhost-from-error-listen-eaddrinuse – veritas May 02 '22 at 13:28

In windows 10, open task manager and go to Details tab.
There you will find node.exe running.
End that task and your port will be released.

If you're using VS Code in Windows, You would need to first KILL all the previous instances of your Node-App

Afterwards, Open the BASH terminal in VS Code and run below command

cmd "/C TASKKILL /IM node.exe /F"

EADDRINUSE means there is already another running process that is listening to the port your node app wants to use and has it reserved. It's most likely you've run the app previously but it hasn't terminated properly and is still holding on to the port. so first we terminate already running one,then only start another new one server

That's because port 3000 is already busy listening to another process. so just go to task manager and end that process/ delete all node js related processes.
