node.js forever daemon, how to exit properly?

When using forever to run a node.js program as a daemon i.e. 

forever start myNodeTask

If the daemon (myNodeTask) decides it needs to exit, what is the correct way to do so?

If I just call process.exit() the program does terminate but it doesn't delete the forever log file, which leads me to believe that I need the program to exit in a more forever-friendly manner.

The node tasks I'm running are plain tcp servers that stream data to connected clients, not web servers.

The forever module always keeps the log files, even after a process has finished. There is no forever-friendly manner to delete those files.

But, you could use the forever-monitor module, which allow you to programatically use forever (from the docs):

var forever = require('forever-monitor'),
    fs      = require('fs');

var child = new (forever.Monitor)('your-filename.js', {
  max: 3,
  silent: true,
  options: []
});

child.on('exit', function () {
  console.log('your-filename.js has exited after 3 restarts');
  // here you can delete your log file
  fs.unlink('path_to_your_log_file', function (err) {
    // do something amazing
  });
});

child.start();
