How to play music from a local directory using node.js and mopidy?

Hi.
I am wondering how I am able to play music from a local folder using mopidy and node.js.

I have installed mopidy, and I am able to get the server up and running when I type mopidy in the OSX’s terminal window.
I have also made a node.js project, and I am able to connect to the mopidy server by doing the following:

var Mopidy = require('mopidy');

var mopidy = new Mopidy({
webSocketUrl:"ws://localhost:6680/mopidy/ws/",
callingConvention:"by-position-or-by-name"
});

I am also able to see if the mopidy s online, but I am not able to play any music.

mopidy.on("state:online", function () {
        console.log("mopidy is online! Lets try to play music");
        mopidy.playback.play();
        mopidy.playback.getState().then(function(res){
            console.log("result form getState",res); // prints stopped
        });
        mopidy.playback.getCurrentTrack().then(function(res){
            console.log("result form get current track",res); // prints null
        });

        mopidy.tracklist.getTracks().then(function(res){
            console.log("got tracks result",res); // prints []
        });
        mopidy.tracklist.getLength().then(function(res){
            console.log("got length result",res); // prints 0
        });

        mopidy.tracklist.getTlTracks().then( function (tracklist) {
           console.log("tracklist result",tracklist); //prints []
        });
        mopidy.playlists.asList().then(function(res){
            console.log("result for playlists",res); // prints []
        })
    });

my config file looks like this:

 [local]
    enabled = true
    media_dir = /Users/johnedvard/Dropbox/Musikk
    #scan_timeout = 1000
    playlists_dir = $XDG_DATA_DIR/mopidy/local/playlists
    tag_cache_file = $XDG_DATA_DIR/mopidy/local/tag_cache
    #excluded_file_extensions = 
    #  .directory
    #  .html
    #  .jpeg
    #  .jpg
    #  .log
    #  .nfo
    #  .png
    #  .txt

I run mopidy local scan and get the following:

INFO     Starting Mopidy 1.1.2
INFO     Loading config from builtin defaults
INFO     Loading config from /Users/johnedvard/.config/mopidy/mopidy.conf

then I run mopidy and get this:

Am I missing something in order to play music?

After playing around with the API, I finally figured it out. I had to use the LibraryController and search for the tracks that are located on the "local" uri, then add the tracks to the TracklistController in order to use the PlaybackController to play the musc. Phew :sweat_smile:

var Mopidy = require("mopidy");
var mopidy = new Mopidy({
        webSocketUrl:"ws://localhost:6680/mopidy/ws/",
        callingConvention:"by-position-or-by-name"
    });
    mopidy.on("state:online", function () {
        console.log("mopidy is online! Lets try to play music");
        mopidy.library.search({"uri":["local"]}).then(function(res){
            mopidy.tracklist.add([res[0].tracks]);
            mopidy.playback.play(); // now we are playing music!!!!
        });
    });

If any of you have any comments about the code, or any tips on best practices and so forth, please tell :grinning:
