EmbarkJS - Communication
========================
**initialization**
For Whisper:
.. code:: javascript
EmbarkJS.Messages.setProvider('whisper')
For Orbit:
You'll need to use IPFS from master and run it as:
``ipfs daemon --enable-pubsub-experiment``
then set the provider:
.. code:: javascript
EmbarkJS.Messages.setProvider('orbit', {server: 'localhost', port: 5001})
**listening to messages**
.. code:: javascript
EmbarkJS.Messages.listenTo({topic: ["topic1", "topic2"]}).then(function(message) { console.log("received: " + message); })
**sending messages**
you can send plain text
.. code:: javascript
EmbarkJS.Messages.sendMessage({topic: "sometopic", data: 'hello world'})
or an object
.. code:: javascript
EmbarkJS.Messages.sendMessage({topic: "sometopic", data: {msg: 'hello world'}})
note: array of topics are considered an AND. In Whisper you can use
another array for OR combinations of several topics e.g
``["topic1", ["topic2", "topic3"]]`` =>
``topic1 AND (topic2 OR topic 3)``
