Welcome to the Find The Difference Game repository – a web app built with TypeScript, Angular, Node.js, Express, and Firebase, with a mobile client developed in Flutter and Dart. This multiplayer game challenges users to identify differences between two images, featuring a robust backend with Socket.IO for real-time communication. The game creation system includes drawing tools for image manipulation, and data persistence is managed through Firebase. The app was originally deployed on GitLab Pages and AWS.

The codebase consists of multiple clients and a single server:

• Desktop Client: Angular-based web client
• Android Client: Flutter-based mobile client
• Server: Node.js/Express backend

• Real-time Multiplayer: Play with others using Socket.IO
• Game Creation: Create custom Find-The-Difference games
• Authentication: User accounts with Firebase
• Mobile Support: Play on Android with dedicated Flutter client
• Drawing Tools: Edit and create game images
• Leaderboards: Track high scores and game stats

• Frontend: Angular, TypeScript, Socket.IO client
• Mobile: Flutter, Dart
• Backend: Node.js, Express, Socket.IO
• Database: Firebase Realtime Database
• Authentication: Firebase Auth
• Deployment: AWS, GitLab Pages

For security reasons, authentication files are not included in the repository. Template files are provided for configuration. Firebase credentials must be added manually after cloning the repository.

This project was developed as part of a university course (LOG3900) at Polytechnique Montréal, in a team of 6 students.
