The Playlyfe Javascript allows developers to access the Playlyfe API in browser applications. This sdk uses the OAuth 2.0 implicit grant flow to obtain an access token which can then be used to make API calls.
Visit the official Playlyfe Developers Documentaion
Note: Breaking Changes this is the new version of the sdk which uses the Playlyfe api v2 by default if you still want to use the v1 api you can do that so by passing a version key in the options when creating a client with 'v1' as the value.
If you haven't created a client for your game yet just head over to Playlyfe and login into your account, and go to the game settings and click on client. Select no for the first 2 questions as we aren't going to use a backend server nor do we have a login system.
| Note: The Implicit Flow works only in production as the player has to be a user on playlyfe. So create a client in production only.
In this flow you need to pass your client_id and redirect_uri. Then you need to authenticate your user to the playlyfe Website using the login url and after authentication, the Playlyfe Server will make a get request to the redirect uri with the access token. Below is a simple single page application that opens up a notification stream to receive notifications.
Playlyfe.init({
client_id: 'YOUR_CLIENT_ID',
redirect_uri: 'YOUR_REDIRECT_URI',
version: 'v1'
});<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript" src="pl.min.js"></script>
<script type="text/javascript">
var player_id = 'YOUR_PLAYER_ID';
var env = 'YOUR_GAME_ENVIRONMENT ( "staging" or "production" )';
var game_id = 'YOUR_GAME_ID';
var notification_handler = function (data) {
console.log("Received Notification: ", data);
}
// Open up a front-end client
var client = new Playlyfe.init({
client_id: 'YOUR_CLIENT_ID',
redirect_uri: 'YOUR_REDIRECT_URI',
version: 'v1'
});
// If the user is not logged in then login
if (Playlyfe.getStatus().msg !== 'authenticated') {
client.login();
} else {
// Fetch a notification stream authorization token
client.api('/notifications/token?player_id=' + player_id, 'GET', function (data) {
// Open a notification stream for a specific player
Playlyfe.openNotificationStream(env, game_id, player_id, data.token, notification_handler);
});
}
</script>
</head>
<body>
<h1>Logging In</h1>
</body>
</html>In this flow your own backend server has to generate a json web token and send it to the frontend when a user logs in. This will authenticate the user as a player on Playlyfe and make requests on his behalf. To generate the JWT you can use any of our backend sdks as they provide this functionality for you already. You can checkout Node SDK for more information on implementing the backend part.
Playlyfe.init({
jwt: 'the json web token sent from your backend on user login'
});<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js" ></script>
<script type="text/javascript" src="pl.min.js"></script>
<script type="text/javascript">
var player_id = 'student1';
var env = 'staging';
var game_id = 'are';
var notification_handler = function (data) {
console.log("Received Notification: ", data);
}
// Open up a front-end client
var client = new Playlyfe.init({
version: 'v1',
jwt: 'jwt token here'
});
client.api('/player', function(data) {
console.log(data);
});
// Fetch a notification stream authorization token
client.api('/notifications/token', 'GET', function (data) {
console.log(data);
// Open a notification stream for a specific player
Playlyfe.openNotificationStream(env, game_id, player_id, data.token, notification_handler);
});

</html>##Usage
###Step 1: Include the Playlyfe JS SDK in your page. The js sdk requires an ajax transport to function properly. Since jQuery has become a ubiquitous library on almost all sites we decided to decouple the ajax transport from the core sdk to cut down the size. You must include either jQuery(or Zepto for mobile applications) before the Playlyfe JS SDK.
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="pl.min.js"></script>
###Step 2: Create a new client This initializes the playlyfe js sdk and attempts to connect to Playlyfe. Your Client ID and can be found in the clients menu in the Game Builder.
Playlyfe.init({
version: 'v2',
client_id: 'YOUR_CLIENT_ID',
redirect_uri: 'YOUR_REDIRECT_URI',
});
Note that the page at the redirect uri must also have the Playlyfe-JS-SDK script included and configured to successfully complete the Implicit Grant Flow and store the access token which will be provided.
###Step 3: Make an api call
You can now make an API call to Playlyfe using the api function.
Playlyfe.api('/player', function(data) {
console.log(data);
});
Your client has certain access control restrictions. There are 3 kind of resources in the Playlyfe REST API they are,
1./admin -> routes for you to perform admin actions like making a player join a team
2./design -> routes for you to make design changes programmatically
3./runtime -> routes which the users will generally use like getting a player profile, playing an action
The resources accessible to this client can be configured to have a read permission that means only GET requests will work.
The resources accessible to this client can be configured to have a write permission that means only POST, PATCH, PUT, DELETE requests will work.
The version restriction is only for the design resource and can be used to restrict the client from accessing any version of the game design other than the one specified. By default it allows all.
If access to a route is not allowed and then you make a request to that route then you will get an error like this,
{
"error": "access_denied",
"error_description": "You are not allowed to access this api route"
}Initializes the sdk with the given configuration.
| Parameter | Description |
|---|---|
| client_id | Client ID of the application. |
| redirect_uri | URI to which the user is redirected after approving the application on playlyfe. |
| debug | Print debug output in the console window. (default: false) |
| jwt | The Json web token of the authenticated user |
Execute an API call. Visit the complete API reference
Returns the status of the user's session since the last time playlyfe.com was contacted.
Returns a url that can be used to login into the application on Playlyfe. Can only be used after calling init.
Returns a url that can be used to logout of the application on Playlyfe. Can only be used after calling init.
Open a notification stream for the specified player in a game in a particular environment (staging or production). The token value here must be obtained from the route /notifications/token after authenticating the client. You can also pass in the token information from your own backend after generating it over there through a server side API to the /notifications/token endpoint.
