ProtoCitySim was a 1 month prototype to integrate a TypeScript React game into a Discord Activity. The goal of the project was to complete a full-stack application through the use of AI assisted coding.

Tools I explored using for the creation:

• ChatGPT - Coding and design assistant.
• GitHub Copilot - Project setup and coding agent.
• Cline VSCode Extension - Task planning and code execution
• GitHub - automated unit testing and CI deployment
• Playwrite - automated integration testing
• Firebase - Firestore and authentication
• Draw.io - Diagrams and design planning

Throughout the project I documented progress on my BlueSky @ https://bsky.app/profile/jonaswills.com

Ultimately, the project was mostly a success. The game supported simple actions sent to Firebase functions that would alter the user records. The project was runnable in Discord and was a great first dip into understand the technical details of creating Discord Activities: CSPs, reactive style-sheet support and user authentication. There were some challenges in the resource calculation and command syncing, but weren’t critical to fix for the goals of the project.
