Overview:

The Real-Time Subway Status Tracker is a web application designed to provide commuters and transit enthusiasts with up-to-date information on subway systems. The app fetches real-time subway status updates using gRPC and displays the current status of every subway line. The goal is to offer a fast, reliable, and mobile-friendly interface for tracking subway service changes and delays.

Key Features:

• Real-time Status Updates: Displays live updates on subway statuses using gRPC.
• Mobile Compatible: Fully responsive, offering a seamless experience on both desktop and mobile devices.
• Comprehensive Coverage: Shows the status of every subway line, with the latest update shown alongside each one.

Tech Stack:

• Backend: The backend is built in Python, leveraging gRPC for communication to provide real-time updates. It is deployed on a serverless infrastructure using DigitalOcean, ensuring scalability and low-cost operation.
• Frontend: The frontend is built using TypeScript and Next.js, providing a fast, modern interface. The app is fully mobile-compatible, allowing users to check subway statuses on the go.
  

Infrastructure:

• Digital Ocean Serverless: Serverless infrastructure ensures scalability, automatic management of resources, and low operational costs.
• Frontend (Vercel): Vercel is used for continuous integration (CI) and continuous deployment (CD) for the frontend. The platform automates the deployment process, ensuring any updates to the codebase are quickly reflected in production. Vercel’s edge network provides fast load times globally, and its serverless functions allow seamless interaction with the backend.
• CI/CD Pipeline: For the frontend, Vercel automates the entire deployment process, ensuring each commit triggers tests, builds, and automatic deployments. This ensures a smooth, efficient development process and minimizes downtime.
