Using Monster Events

Monster UI use postal.js as a local message bus (pub/sub system). It is mostly used to subscribe and publish Common Controls into applications and is wrapped inside Monster methods to simplify their invocation.

Subscribe

Named Functions

To subscribe to a specific function, the following steps need to be respected: * in the app variable exists an object called subscribed; inside it link the function to subscribe to to a topic name:

subscribe: {
    'topicName': 'functionName'
}
  • respect the naming conventions and name the topic following this rule: {appName}.{commonControl}.{functionName}

Anonymous Functions

To subscribe to an anonymous function, the following steps need to be respected: * call the Monster method:

monster.sub(topic, callback, context);
  • respect the naming conventions and name the topic following this rule: '{appName}.{commonControl}.{functionName}'
  • the context parameter is optional and will be used as this in the callback

Publish

Thanks to Monster UI core methods, publishing is really easy:

monster.pub(topic, data);

The topic should follow the rule: '{appName}.{commonControl}.{functionName}' The data parameter can be a callback or an object containing a function used as callback.
