How to kill an open process on node.js?
If you want to kill all processes than:
sudo killall -9 node
If you want to kill process on selected port than:
sudo kill sudo lsof -t -i:3100
That was port 3100
Use the following set of commands to identify the process running on a given port and to termiate it from the command line
sudo fuser -v 5000/tcp // gives you the process running on port 5000
It will output details similar to the one shown below
USER PID ACCESS COMMAND
5000/tcp: almypal 20834 F.... node
Then use
sudo fuser -vk 5000/tcp
to terminate the process. Check once again using
sudo fuser -v 5000/tcp
to ensure that the process has terminated.
On Windows you could use the following steps
C:\> tasklist // will show the list of running process'
Image Name PID Session Name Session# Mem Usage
System 4 console 0 236 K
...
node.exe 3592 console 0 8440 k
Note the PID corresponding to your node process, in this case 3592. Next run taskkill to terminate the process.
C:\> taskkill /F /PID 3592
Or /IM switch
C:\> taskkill /F /IM node.exe
From within Node.js:
var die = function(quitMsg)
{
console.error(quitMsg)
process.exit(1);
}
die('Process quit');
There are certain methods available for exiting that are only available for POSIX (i.e. not Windows) that will exit a process by its process id.
Also, note that you might be able to send a kill() signal using this method, which does not say it isn't available for Windows:
process.kill(pid, [signal])
