MinPubSub
=========
[](https://cdnjs.com/libraries/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 [NPM](https://www.npmjs.com/package/minpubsub) and [Bower](http://bower.io/search/?q=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){ ... }
```javascript
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:
```javascript
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:
```javascript
var handle = subscribe("/some/topic", function(){});
unsubscribe(handle);
```
