Scoreflex Javascript SDK

Getting Started

  1. Create a Scoreflex developer account at Don’t forget to validate your account if you signed up via an email and password pair before continuing.
  2. Download the last JavaScript SDK release on GitHub at
  3. Import the SDK and the webclient style if you intend to use it in your JavaScript game.

    <script type="text/javascript" src="scoreflex.js"></script>
    <link href="style/styles.css" type="text/css" rel="stylesheet">
  4. Start using the Scoreflex JavaScript SDK. Your clientId and clientSecret are indicated on the game page of your Scoreflex developer account.

    var useSandbox = true;
    var ScoreflexSDK = Scoreflex(/*clientId*/, /*clientSecret*/, useSandbox);

Developer's Guide

Cross-Origin Resource Sharing (CORS)

In order to contact the Scoreflex backend, the JavaScript Scoreflex SDK makes use of the Cross-Origin Resource Sharing specification from the W3C enabling browsers to reach external domains with AJAX requests. Consequently, only browsers compatible with CORS can safely request the Scoreflex backend ( ).

Scoping the SDK

It is advised to instanciate the Scoreflex SDK in a non-public scope to avoid easy access to the API by your players (which facilitate cheating).

/* -- public scope -- */
var myGame = (function() {
  /* -- inner private scope with closure-- */

  var useSandbox = true;
  var ScoreflexSDK = Scoreflex(/*clientId*/, /*clientSecret*/, useSandbox);

Players, Leaderboards and Challenges objects

The Players, Leaderboards and Challenges objects are members of the ScoreflexSDK instance. They provide factory methods to get Player, Leaderboard and ChallengeInstance objects. They also provide generic methods to display some webviews.

  • The Player object gives access to player's data and webviews.
  • The Leaderboard object has methods to submit scores and display full and tiny leaderboards (rankbox) webviews. A Leaderboard reference is passed in the leaderboard parameter of a ScoreflexPlayEvent event.
  • The ChallengeInstance object has methods to get a challenge instance's state, players, and turn information, as well as methods to send a new turn and display the detailed webview. A ChallengeInstance reference is passed in the challenge parameter of a ScoreflexChallengeEvent event.
/* Get the current player’s nickname */
var player = ScoreflexSDK.Players.getCurrent();
var nickname = player.getNickname();

/* Submit a score to a leaderboard */
var leaderboard = ScoreflexSDK.Leaderboards.get("BestScores");

/* Display the challenges of the current player */

Custom Requests

The JavaScript Scoreflex SDK also provides methods to send custom REST requests to the Scoreflex backend. For instance you can create new challenge instances for your players without using the Scoreflex web interfaces, get JSON data from the Scoreflex backend, or display a Scoreflex web interface not aliased by the SDK.

/* Create a new challenge for a player (with random opponent) */"/challenges/requests", {configId:"myChallengeConfigId"});

/* Display web interface listing your games on Scoreflex  */
var myDeveloperId = "xxxyyyzzz";
var path = "/web/developers/"+myDeveloperId+"/games";;
