Railbeam

Added two foundational backend features to the Railbeam - Stardance project. First, we integrated PostgreSQL support to provide a robust, scalable database solution. This replaces earlier stateless approaches, enabling persistent data storage for user sessions, game states, and real-time analytics. The PostgreSQL setup includes optimised schema design and connection pooling for performance.

Introduced a region-aware server model, which dynamically routes user traffic to geographically optimal server instances. This reduces latency for global users and ensures localized compliance for data residency requirements. The model uses IP geolocation and load-balancing logic to adapt to user locations in real time.

Current Status
With these updates, the backend now offers a stable infrastructure for handling complex user interactions and global scalability. The region-aware server is active in staging, and PostgreSQL is fully integrated into the development environment. Next steps include testing cross-region synchronization and refining database query optimizations for high concurrency.

Things Learnt

• Database Integration: Adopting PostgreSQL required careful migration planning and schema validation to avoid data inconsistencies. We learned to prioritize connection resilience and indexing strategies for high-traffic scenarios.
• Geolocation Challenges: Implementing region-aware routing highlighted the trade-offs between latency, cost, and user distribution. We refined the logic to prioritize server proximity without compromising on centralized data management.
• Testing Workflows: Automated testing for database transactions and region routing is critical. We leaned into mock servers and load-testing tools to validate reliability under stress.

The project has seen rapid progress this week, with a focus on foundational backend setup and UI design. Key milestones include:

• Active Storage Configuration: Initial work was done to set up Rails’ Active Storage for S3 integration (July 7), enabling scalable media management.
• Dark Theme Design System: A full dark theme was implemented using CSS variables and modular components (July 8), ensuring consistent styling across the app.
• Landing Page & Home Page Overhaul: A redesigned landing page and updated home page with status group styling were added (July 8), emphasizing clean, responsive layouts.

Current status: The backend is primed for media uploads, and the frontend has a cohesive dark theme and redesigned home/landing pages. Remaining work likely involves finalizing theme toggles and integrating storage with the UI.

Lessons learned:

• Active Storage and S3 setup in Rails requires careful configuration of credentials and bucket policies.
• Modular CSS design systems (like a dark theme) streamline component styling and future maintenance.
• Merging CDN-related changes early improves asset performance and simplifies later deployments.
