Ampache
=======

Communicate to an Ampache server using the API

Usage
-----

``` js
var AmpacheSession = require('ampache');
var conn = new AmpacheSession('user', 'pass', 'http://example.com/server/xml.server.php');
```

Examples
--------

#### Authenticate to an ampache server (assumes `conn` is set from the above usage)

``` js
conn.authenticate(function(err, body) {
  console.log(body);
});
```
yields
``` json
{
  "auth": "510b0a5f0f0e076ebab1df731acbbaeb",
  "api": 350001,
  "update": "2012-05-23T03:32:01+00:00",
  "add": "2012-08-07T09:32:17+00:00",
  "clean": "2012-08-07T09:32:29+00:00",
  "songs": 8043,
  "albums": 862,
  "artists": 372,
  "playlists": 0,
  "videos": 9
}
```

The dates in the above examples are JavaScript `Date` objects

#### Get a list of artists

``` js
conn.get_artists(function(err, body) {
  console.log(body);
});
```
yields
``` json
{
  "391": {
    "@": {
      "id": "391"
    },
    "name": "The American Dollar",
    "tag": {
      "#": "Post-Rock",
      "@": {
        "id": "7",
        "count": ""
      }
    },
    "albums": "2",
    "songs": "24",
    "preciserating": {},
    "rating": "0"
  },
  "392": {...},
}
```

#### Query the Ampache server for a given artist id

``` js
conn.get_artist(249, function(err, body) {
  console.log(body);
});
```
yields
``` json
{
  "@": {
    "id": "249"
  },
  "name": "Lights",
  "tag": {
    "#": "Pop",
    "@": {
      "id": "11",
      "count": ""
    }
  },
  "albums": "1",
  "songs": "13",
  "preciserating": {},
  "rating": "0"
}
```

#### Ping the ampache server to prolong your session

``` js
conn.ping(function(err, body) {
  console.log(body);
});
```
yields
``` json
{
  "session_expire": "Fri, 10 Aug 2012 07:05:09 +0000",
  "server": "3.6-Alpha1-DEV",
  "version": 350001,
  "compatible": 350001
}
```

The date in the above example is a JavaScript `Date` object

#### Send an api call

Circumvent the built-in convenience methods and hit the api directly

``` js
conn.call_api({'action':'playlists'}, function(err, body) {
  console.log(body);
});
```
yields
``` json
{
  "1": {
    "@": {
      "id": "1"
    },
    "name": "AILD - Decas",
    "owner": "Administrator",
    "items": "12",
    "type": "public"
  },
  "2": {
    "@": {
      "id": "2"
    },
    "name": "AILD - The Powerless Rise",
    "owner": "Administrator",
    "items": "11",
    "type": "public"
  }
}
```
