- Add a docker compose file to start the entire stack with a single command
- Update dependencies to the latest version
- Replace the current ad-hoc monitoring feature with something like influxdb + grafana.
GameHub.io is an attempt to make a real-time multi player gaming server using the following technologies:
- HTML5, CSS3, Twitter bootstrap and Font awesome to make a nice looking UI
- JQuery combined with the inevitable Javascript utilities (Lodash, Moment.js, Messenger.js and Highcharts) for client side logic
- Socket.io client to make real time gaming possible
- Node JS as web server
- Express JS as web framework
- Passport JS as authentication middleware
- Socket.io server to make real time gaming possible
- Handlebars.js to easily render HTML templates
- Mongo DB along with Mongoose
- ElasticSearch server for (near) real time game indexing and lookup
The main goal of GameHub.io is to provide a non trivial web application serving as an example of gaming server using the aforementioned technologies.
Here is a list of core features:
- Application structure and setup
- User authentication and registration process (/login & /register)
- Real time multi player gaming logic (See gaming logic section)
- RESTful API (/api)
- Real time monitoring dashboard (/monitor)
- "TV" page to broadcast any real time content (/tv)
- Real time game indexing and searching using ElasticSearch (/search)
GameHub.io uses a simple gaming sequence through Socket.io that works for 2+ players. Here is a simplified diagram of most relevant events:
- Each player can create a game by sending a 'create-game' event to the server
- The server creates a new game and replies to the player with a randomly generated token for the game
- The player sends this token to other players and waits for them to join the game
- Others players join the game by sending a 'join-game' event to the server
- Once all players joined the game, the server joins players sockets to the same socket.io room
- At this point, the game starts: depending on the game nature, each player can send a random number of events that will be broadcast to other players.
- When the game is over, each player is notified and sockets leave the game room
ChessHub.io is a real time multi player chess server that serves as a sample of how to reuse GameHub.io core features.
The goal of ChessHub.io is not to provide a fully featured web application to play chess online.
Even though the application is related to chess, it is easy to change the domain model along with application logic and keep/adapt the application structure.
- Because it is a good use case for real time multi player gaming
- Because every time you look for a real time application example on the web, you end up on chat applications, so I decided to change the landscape :-)
- Because I am a chess junkie!
Chess logic on the client side uses the excellent Chess.js and Chessboard.js libraries.

- Node JS
- Mongo DB up and running on the default port (27017) and using the default database (test)
- ElasticSearch server up and running on the default port (9200)
$> npm install
$> bower install
$> node initData.js
$> node .
Browse the following address: http://localhost:3000
You can register a new account or sign in with the following credentials: [email protected] / foobar
Note: The initData.js script will populate Mongo DB and ElasticSearch with some data so you can use the application.
Example: /api/user/Foo
{
"id": "54564692985517c304587d01",
"name": "Foo",
"email": "[email protected]",
"lastConnection": "2014-12-02T23:50:59.218Z"
}Example: /api/game/5456476066be11c704942161
{
"id":"5456476066be11c704942161",
"user":"54564692985517c304587d01",
"white":"Foo",
"black":"Anonymous",
"pgn":"1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. O-O Bc5 5. c3 O-O 6. d4 exd4 7. cxd4 Bb4",
"result":"1-0"
}There are probably some points of improvement in the application design, structure or code.
If you believe there is a best practice I have not followed, please let me know by opening an issue on the issue tracker. Pull requests are welcome!
