BeastLounge
Description
This is a multi-user gaming server which allows users to register and play Blackjack against the dealer with up to 5 other players at each table. The game is run on a server written in C++ using Boost.Beast, and a client written in JavaScript which runs in the browser and is delivered by the game server.
The WebSocket protocol is used to communicate between the client and server. This allows for full-duplex unsolicited messaging. WebSocket is built-in to JavaScript and a natural choice. Each message contains in the payload a complete JSON-RPC object as described here: https://www.jsonrpc.org/specification
A lobby area offers multiple public and private chat rooms similar to IRC where users can meet, add each other to their friends list, send direct messages (whispers), and join games together. The lobby lists games in progress or games starting and gives users the option to join.
