Game leaderboard node js

In the previous blog postwe described some thoughts on how to design a game leaderboard and how to represent it programmatically. As the name implies, this project is about game leaderboards using Azure Functions with Node. On the architecture side of things, the API itself is written in Node. You can deploy the project to your own Azure subscription via one-click ARM deployment. Alternatively, you can deploy the project via a Docker container.

Kubernetes deployment YAML files are also included if you wish to deploy the project to your K8s cluster. When running locally, everything is logged to standard output console. The API supports many operationsfrom posting a new score to getting top scores, daily scores etc.

Azure Functions is based on Azure App Service which offers a mechanism which you can use for authentication of your service with well-known providers such as Azure Active Directory, Facebook, Google, Microsoft Account, and Twitter. You are encouraged to use one of these or implement your own functionality.

Read here for more details on how to use authentication for the API. If you encounter any issues, feel free to raise an issue on the GitHub repo.

Lets make a global leaderboard that anyone playing our game can submit scores to. Single player games are fun, but showing your Tetris prowess to the world requires a little more technology.

We are going to set up a basic server with a simple database. This allows us to permanently store any game or player data we want and make it easily accessible. This makes it ideally suited to HTML5 games and apps, as you can use Javascript for both the client and server parts of your project. Installing Node. From here you can download the current version of node.

If this happens, accept it, this simply allows you to access Node from anywhere. To verify your install, open a command prompt window, and type node -version. Our server is great, but to store data permanently we need a database.

We will use MongoDB. This is great as we can easily convert between JSON and our game objects. You now have the two key things to create your server. First we will create our server in a file called server. We want the ability to retrieve the current high scores and add our own.

We can do this by defining a submitScore route and a highScores route which we will fill in later. Note the first 3 require statements.

These allow us to include extra node modules that will be very useful, but they must first be installed. Luckily we can do this without leaving our command window. That node. Open a command prompt in the same directory as server. From there type the following 3 lines one after the other. This makes it trivial to add modules to your project. Now for some fun. To start the database, open a command window in the directory where you installed the binaries of MongoDB.

In a new command window. This opens a connection to the database that we can see in the command window so this is a client that is connected to the database serverit also verifies that Mongo is running correctly.

We can finally start the node. Open one final command window in the directory of your server. Simply type "node server".

If everything has worked correctly, you should now be looking at a command window that says "Listening on port ". We have our server running, but we have no application to make use of it. Let's make a quick detour and program a very simple app that can use our server. This app will simply generate a score, send it to the server and retrieve a list of scores.The Leaderboards Javascript SDK allows you to easily submit scores and show a full Miniclip leaderboard for all of the submitted scores from your game.

The leaderboard contains various features such as a global leaderboards, friends leaderboards, event leaderbaords and time filters.

The level list needs to be set during the SDK initialization. Either by defining the min and max number of levels, or by describing the complete level list. Gets raw JSON data containing the logged in users current highscore in the specified level.

In this case it is the Leaderboard module. Parameter Type Description level integer The level of the game for which you want to display the leaderboard callback function his is called upon opening and closing of the leaderboard. The callback passes back 1 and 2 back respectively for these conditions.

Now, we need to connect to the database we created in mLab in this case sweetgameand make a collection called players that will contain records of all our players.

Restart the server and open up Postman. Head over to your mLab account and check the sweetgame database specifically the players collection. This confirms that everything is working as it should.

Restart the server, head into Postman, and update the score of the player you created above to Before we create the route for the leaderboard, go ahead and create a few more players with varying scores using the POST request in Postman like in Step 2.

Now, the client the game should be able to use this route to request a specified number of top players.

After the player has logged into our game, they will be able to view the leaderboard and submit new high scores to the database. Lastly, our server will also be responsible for hosting our Phaser game. The goal of this tutorial is to teach you the basics of adding user authentication to your game and how to create a leaderboard. You will learn how to:. You can download all of the files associated with the source code for Part 1 here.

For this tutorial, we will be using Node. In order to follow along with this tutorial, you will need to have Node. Having prior experience with these tools is a plus, but it is not required for this tutorial.

We will not be covering how to install these tools as the focus of this tutorial is making a leaderboard with Phaser. To install Node. When you install Node. Once you have these tools installed, you can move on to the next part.

Also, at the time this tutorial was created, the latest LTS version of Node. It is recommended you be on this or a new version when following along. Lastly, for this tutorial, we will be using MongoDB Atlas for our database.

You are welcome to use a local version of it, or another cloud solution for your database, but that is outside the scope of this tutorial. For our database, we will be using MongoDB and for this tutorial, we will be using its Atlas cloud service to host our database.

The server side code is written in JavaScript using Node. To use this code you will need a web server that allows you to host your own node. There are plenty of super cheap VPS providers around these days so if you go that route take a look at my article on installing node on your own VPS here.

You will also need Redis, take a look at my article on installing Redis here. Once you have everything installed and setup, run main. Once running, the server will be listening for connections from Unity on the default port which is set in server.

The code in server,js is straight forward and much of it was already covered in this article here. The main changes include dealing with data hiding, we now pass the data base64 encoded via the d parameter:. Here we decode the base 64 string data then pass it on to be processed.

This enables me to encrypt the data at the other end then decrypt it when it arrives at this end not covered in this articlethis will allow me to hide what is sent and minimise the chance that someone spams my leaderboards with fake data.

The next major change is to handle commands that are passed to the server, to allow the client to perform different actions such as submit a score or get the users rank etc.

The leaderboard class handles all of this including pushing multiple commands to Redis in one go instead of sending them separately to speed things up. For example sending scores to multiple leaderboards at the same time:. The Unity client code is implemented in Leaderboards. Lets take a quick look at the code:.

Internally each request to the server is called via a coroutine and the supplied callback that we pass is called when a response from the server comes in, e. Its also worth mentioning that when we send data to the server we make some effort to hide it which makes it a little harder for someone to spam the server with false scores, e.

Note how we firstly encode the data to bytes then convert it to a base 64 string, this enables us to add a step between, where we can encrypt the byte data using whatever means we like. I plan to extend the server to allow queries of the data, so I can for example view all of the leaderboards from a website and possibly on device.
