Issue Description
Current server.js lacks critical features needed for a production-ready application.
Problems Found
1. No Graceful Shutdown
When server receives SIGINT/SIGTERM, database connections are not closed properly.
Risk: Connection leaks and data corruption.
2. No Environment Validation
Server starts without checking required environment variables.
Risk: Runtime errors when variables are missing.
3. Basic Health Check
Only returns "OK" status, doesn't verify database connectivity.
Risk: Can't monitor actual service health.
4. CORS Only for Development
No production CORS configuration.
Risk: Security issues in production.
5. Generic Error Handler
All errors return 500 with same message.
Risk: Poor debugging experience.
Proposed Solutions
1. Graceful Shutdown
const gracefulShutdown = async (signal) => {
console.log(`Received ${signal}. Shutting down gracefully...`);
// Close MongoDB
await mongoose.connection.close();
console.log('MongoDB connection closed');
// Close Redis
await redisClient.quit();
console.log('Redis connection closed');
// Close server
server.close(() => {
console.log('Server shut down successfully');
process.exit(0);
});
};
process.on('SIGINT', () => gracefulShutdown('SIGINT'));
process.on('SIGTERM', () => gracefulShutdown('SIGTERM'));
