How to kill an open process on node.js?

Question

I'm trying to set up a build-system for Node.js on sublime, so I can press F7 to call "node" on the openned file. The problem is that the process is then open forever, so, the second time I use F7 I get an add-in-use.

Is there a way I can kill the openned "node.exe" process from node.js?

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])
