The Radiodan client is installed as an npm module, which means server-side nodejs code can access the objects. We've also provided a connect middleware to provide access to the same objects in the browser.

Using the middleware

Using Express:

var app      = require('express')();
var radiodan = require('radiodan-client');

// mount the middleware at /radiodan
// allow requests from other domains (default: false)
app.use('/radiodan',
  radiodan.middleware({crossOrigin: true})
);

// access at http://localhost:5000
app.listen(5000);

Accessing the client-side objects

In your HTML page, link to the radiodan client code (assuming you've mounted the middleware at /radiodan):

<script src="/radiodan/client.js"></script>

This will attach the Radiodan object to window.

Objects exposed by the client-side API

• Player
• Audio Device

Accessing Objects Example

To get an instance of player with id of main:

var player = window.Radiodan.player.get('main');

Sending Commands

The API for each object applies to both the client-side and server-side variants. On the client-side, each command is sent back to the middleware via an AJAX request.

Listening To Events

Events are emitted via an EventSource interface. The Radiodan objects encapsulate this and re-emit events using an EventEmitter object.
