Online Tic-Tac-Toe "BRIBE" Server

Overview

This demo project is the backend server for a two-player online Tic-Tac-Toe web app "BRIBE". I implemented a registration-free matching system using JWT tokens and invitation URLs. In addition to that, "bribe" system makes this game definitely funnier than conventional tic-tac-toe!

Built with natural language

As a complete beginner with no prior programming experience, I started this project after just a basic tutorial in Go. With the help of ChatGPT, I managed to build this server using natural language processing. Although the project has a strong element of being a joke app, I took serious steps to ensure the gameplay process was enjoyable and implemented real-time battle through WebSocket communication. This project allowed me to learn basic development procedures, and I look forward to creating more enjoyable and beneficial projects in the future.
