sudokian.io

Sudoku for a modern age. Creative. Multiplayer. Mobile. Login with Twitter / Facebook / Google

Built an Azure-heavy gaming website based on a 100%-pure Angular (TypeScript) SPA backed by a series of Node.JS (ES6) services. General data (e.g. colors, themes, other static lists) and specific game moves were stored in Azure Table Storage. Game-specific user data, in-game notification data, and social-media sharing data were stored in a CentOS7-hosted MongoDB instance. Azure App services provided Node.JS and HTML5 static hosting with multi-slot deployments for release testing. SVG sprites were setup in Azure Blob storage distributed with an Azure CDN. Styles modularly added with Sass. Authentication and social-media identity services were setup via Auth0. Realtime multplayer interactions were setup with websockets via socket.io.
