Is it possible to create an exit hook in Meteor?

I have a connection to a device. Whenever my app shuts down or the connection to the device is lost, I want to update a collection to set it to a state.

function onExit() {
  Cylon.observer.stop();
  Cylon.connections.update({}, {
    $set: { homed: false }
  });
}
Meteor.beforeExit(onExit);
Cylon.devices.on('disconnect', onExit);

Would there be a way to create exit hooks in Meteor?

You could use this package mizzao:user-status to track the users status and observe your users, for example :

enter image description here

Meteor.users.find({ "status.online": true }).observe({
  added: function(id) {
    // id just came online
  },
  removed: function(id) {
    // id just went offline
  }
});

Meteor application is still an Node.js application, you might consider to use one of the following event listener to do the data update before your application exit

process.on('exit', function() {...})
process.on('uncaughtException', function() {...}}
