This PR introduces Level 3 backend enhancements to elevate AnimateHub’s server to a production-grade, stable, and deployment-ready architecture. The goal is to improve performance, reliability, and scalability — ensuring a smoother experience in real-world environments.
Key Improvements
Graceful Shutdown System
Added signal handlers (SIGINT, SIGTERM) to ensure the server and database connections close cleanly during shutdown or restarts.
Lightweight & Plugin-Free
Removed unnecessary or deployment-risk dependencies, resulting in faster load times and simpler deployment on any platform (Vercel, Render, or Railway).
Enhanced Error Resilience
Introduced robust handling for unhandled promise rejections and uncaught exceptions to prevent unexpected crashes in production.
Asynchronous Optimization
Refined async initialization flow for reliable and race-free database connection setup.
Deployment Readiness Check
Environment variable validation and fallback support ensures flexibility across environments (development, staging, production).
Code Cleanliness & Maintainability
Rewritten for clarity, safety, and maintainability with zero redundant logic or external plugins.
Impact
This upgrade marks a major backend milestone for AnimateHub, aligning the project with enterprise-grade Node.js practices.
More stable runtime behavior
Safer deploys and server restarts
Reduced crash potential
Zero third-party plugin risks
Easier CI/CD integration
Testing
Manually tested using Node.js 18+ on local and mock deployment environments.
All startup, shutdown, and DB connection sequences performed as expected without errors.
Request
Kindly review and consider labeling this PR as Level 3, as it introduces critical backend infrastructure improvements and significantly enhances deployment reliability for AnimateHub.
regards,
Sashreek Das.
