Multiplayer UNO Game using MERN Stack

Overview

This project is a multiplayer UNO game built using the MERN (MongoDB, Express, React, Node.js) stack. UNO is a classic card game where players aim to be the first to empty their hand of cards by matching the card in the discard pile by color, number, or symbol.

Features

• Real-time Multiplayer game: Players can join rooms and play against each other in real-time.
• Chat: Players can chat with each other in the game room. The messages can be reacted and replied to.
• Game Mechanics: Implement UNO game rules such as drawing cards, playing cards, skipping turns, reversing direction, etc.
• Authentication: Allow users to sign up and log in.

We use custom hooks to manage modals, toasts and game state. The long polling is implemented in the channel module, and is made such that it can be easily replaced with socket.io for real-time updates.

Technologies Used

• MongoDB: For storing user data and game state.
• Express.js: To build the backend server and RESTful API endpoints.
• React: For building the frontend user interface and interactive game components.
• Node.js: To run the server-side code and manage dependencies.
• [TODO]Socket.IO: For real-time communication between players in the game rooms. We currently use long polling for real-time updates.

Additionally, we use jest for backend tests.
