Create Database Module with ORM Integration

[memplethee-lab]

Overview

Build a robust database module that handles all data persistence operations for the Alian Structure API using an ORM (Object-Relational Mapping) solution.

Direction

This module should provide:

• Database connection pooling and lifecycle management
• ORM integration (TypeORM or similar)
• Database migration system for schema versioning
• Connection health checks and retry logic
• Support for multiple database environments (dev, staging, production)
• Query builder utilities for common operations

Implementation Details

The database module should abstract database operations through a repository pattern, ensuring clean separation of concerns and testability. It should handle transactions, connection timeouts, and automatic reconnection scenarios.

Acceptance Criteria

• Database connections are properly pooled with configurable pool size
• ORM is configured and working with TypeScript entity decorators
• Migration system allows version control of schema changes
• Connection health checks run periodically and log failures
• Automatic retry logic handles transient connection failures
• Environment-specific database configurations load correctly
• Transaction support for multi-step operations
• Query performance is tested with slow query logs
• Database module unit tests achieve >80% coverage

I'd like to work on this issue by building a production-ready database module that provides a reliable foundation for data persistence across the Alian Structure API. I'll implement a modular database layer using an ORM such as TypeORM, with configurable connection pooling, environment-specific configuration, migration support, health checks, retry logic, and transaction management while following a repository pattern to keep the application clean, maintainable, and easy to test.

The implementation will focus on reliability and scalability by handling connection lifecycle management, automatic reconnection for transient failures, configurable pool sizes, connection timeouts, and periodic health monitoring with appropriate logging. I'll also provide reusable query utilities for common database operations, ensure the migration system supports schema versioning across development, staging, and production environments, and optimize the module for future feature growth without coupling it to specific business logic.

To ensure quality, I'll add comprehensive unit tests covering connection management, repository behavior, transaction handling, retry mechanisms, environment configuration loading, and migration functionality, targeting the required coverage threshold. I'll also validate query performance through slow-query logging and verify that the database module integrates cleanly with the existing architecture while remaining extensible for future entities and services.
