API methods

subscribe

Allows you to subscribe a chosen channel through a listener. When this channel emits something, it will notify all its listener to execute.

radio.subscribe('coffeeChannel', function(data){
  console.log('hi, I will do anything with the data');
});

publish

Allows you broadcast your message through a channel, it allows to send any data as you like.

radio.publish('coffeeChannel', 'macchiato');

unsubscribe

When you invoke subscribe method, it returns to you an object with dispose method:

const subscription = radio.subscribe('demoChannel', (arg) => {
  console.log('this is what i am getting', arg);
});

subscription.unsubscribe();

getChannels

If you want to know which channels you have registered, you can use this method to know that:

radio.subscribe('one', function(d){
  console.log(d);
});

radio.subscribe('two', function(d){
  console.log(parseInt(d) + 13);
});

var channels = radio.getChannels();//['one', 'two']

resetChannels

If you want to reset some channels, you can just use shutdown to reset them.

radio.resetChannels('javascript', 'one', 'coffeeChannel');

It will reset each of these channels, and will dispose all listeners. If you want to reset all channels, just invoke it without args

radio.resetChannels();
