Server cleanup after a client disconnects

Question

Is there a way to detect when a client disconnects from a meteor server, either by refreshing or navigating away from the page, so that the server can attempt some cleanup?<

Answer 1

I'm using Iron Router and call my cleanup code on the unload event of my main controller. Sure this will not catch the event of a tab closing, but still feels good enough for many use cases

ApplicationController = RouteController.extend({
    layoutTemplate: 'root',
    data: {},
    fastRender: true,
    onBeforeAction: function () {
        this.next();
    },
    unload: function () {
        if(Meteor.userId())
            Meteor.call('CleanUpTheUsersTrash');
    },
    action: function () {
        console.log('this should be overridden by our actual controllers!');
    }
});
