App

The app service is the core of Kube, runs services and modules. It provides communication between services and modules through events and API.

Events

Event	Description
start	This event fires immediately when the Kube application start. Before the initialization of modules and services.
started	This event is fired when all services, modules, and other application tools are started.
stop	This event fires when the method app.stop is called. Before the stopping services and modules.
stopped	This event is fired when all services, modules, and other application tools are stopped.

Example of catching app events in your module.

(function($K)
{
    $K.add('module', 'mymodule', {
        init: function(app, context)
        {
            this.app = app;
        },
        // catch event
        onmessage: {
            start: function()
            {
                console.log('app start event');
            }
        }
    });
})(Kube);

Methods

broadcast

Arguments

name	String	modulename.eventname
module	Object	instance of the module (typically 'this' object)

Create an event with the specified name, which can be caught in any other module or in several modules.

(function($K)
{
    $K.add('module', 'mymodule', {
        init: function(app, context)
        {
            this.app = app;
        },
        myBroadcast: function()
        {
            this.app.broadcast('mymodule.success', this);
            this.app.broadcast('mymodule.success', this, arg1, arg2);
            this.app.broadcast('mymodule.success', this, { "arg1": 1, "arg2": 2 });
        }
    });
})(Kube);

How to catch an event in another module.

(function($K)
{
    $K.add('module', 'myanothermodule', {
        init: function(app, context)
        {
            this.app = app;
        },
        onmessage: {
            mymodule: {
                success: function(sender)
                {
                    console.log('Success!');
                }
            }
        }
    });
})(Kube);

The app.broadcast method will automatically create the second module event, which will specify the module element ID or the data-name attribute. For example, create a module element on the page and assign it an ID attribute.

<div id="mymoduleid" data-kube="mymodule">...</div>

Now we can catch the event by module ID in another module.

(function($K)
{
    $K.add('module', 'myanothermodule', {
        init: function(app, context)
        {
            this.app = app;
        },
        onmessage: {
            mymodule: {
                success: function(sender)
                {
                    if (sender._id === 'mymoduleid')
                    {
                        console.log('Success!');
                    }
                }
            }
        }
    });
})(Kube);

api

Arguments

name

String

modulename.methodname or modulename.moduleID.methodname

Call the method of the specified module. If only the module name and the method name are specified, it calls the method of all modules with this name on the page. If a module ID is specified using the id attribute or data-name for an element, it calls the method only for the module with this ID.

The method does not return values, to ensure the independent work of the modules.     If the specified module or method is does not exists in the application, the call will be ignored without generating an error.

(function($K)
{
    $K.add('module', 'mymodule', {
        init: function(app, context)
        {
            this.app = app;
        },
        callModule: function()
        {
            this.app.api('alert.close');
            this.app.api('alert.myalert.close');
        }
    });
})(Kube);

Call from outside.

$K.api('alert.close');
$K.api('alert.myalert.close');

stop

Stop the application. Also calls the stop method (if exists) for all services and modules.

(function($K)
{
    $K.add('module', 'mymodule', {
        init: function(app, context)
        {
            this.app = app;
        },
        stopMyApp: function()
        {
            this.app.stop();
        }
    });
})(Kube);

Call from outside.

$K.api('stop');
