MinPubSub

A micro publish/subscribe messaging framework, weighing in at only 198 bytes gzipped. Created by rewriting Peter Higgins' jQuery plugin, MinPubSub is completely self contained with no external dependencies. Keep your projects loosely coupled with this powerful design pattern. Also available on http://search.npmjs.org/#/minpubsub.

Documentation

Options:

If you don't want these methods added to the window object simply modify the immediate function to pass in the JavaScript object of your choosing.

Methods:
  • publish (String topic, Array? args)

    • summary:

      • Publish some data on a named topic.
    • topic: String

      • The channel to publish on
    • args: Array?

      • Optional data to publish. Each array item is converted into ordered arguments on the subscribed functions.
    • example:

      • Publish stuff on '/some/topic'. Anything subscribed will be called with a function signature like: function(a,b,c){ ... }

        publish("/some/topic", ["a","b","c"]);
        
  • subscribe (String topic, Function callback)

    • summary:

      • Register a callback on a named topic.
    • topic: String

      • The channel to subscribe to
    • callback: Function

      • The handler event. Anytime something is publish'ed on a subscribed channel, the callback will be called with the published array as ordered arguments.
    • returns: Array

      • A handle which can be used to unsubscribe this particular subscription.
    • example:

        subscribe("/some/topic", function(a, b, c){ /* handle data */ });
      
  • unsubscribe (Array handle)

    • summary:

      • Disconnect a subscribed function for a topic.
    • handle: Array

      • The return value from a subscribe call.
    • example:

      var handle = subscribe("/some/topic", function(){});
      unsubscribe(handle);
