start\kill local EXE application with Node.js

I have a local node.js application in windows - is it possible to start \ kill local .EXE application and kill it in my code.

Is it possible? If so, I would be glad to see an example.

Thanks.

If you planning to kill your very own node process, the process API exposes the method exit(), which is indeed a wrapper to the C exit() method. According to the docs, it takes a parameter to specify success or failure.

One very "interesting" thing, then, would be to implement a controller to stop your server. Something like this:

app.post('/stop/server/now', function(){
    process.exit(0);
});

EDIT To kill other processes, you simply need to know their pid (and have enough permission to kill other processes).

First, to get the pids, execute a command to do so. On Linux, this would be:

var exec = require('child_process').exec;

exec("ps aux | grep 'process_to_kill' | grep -v grep | awk '{print $2}'",
  function (error, stdout, stderr) {
    console.log('stdout: ' + stdout);
    if (error !== null) {
      console.log('exec output: ' + error);
    }
});

Then, you pass these pids to the process.kill() API.
