Can I use this for existing projects?

Yes, the skill is designed to scan your codebase for existing patterns and follow your local naming and directory conventions when adding new repository layers.

Does it support transactions?

Yes, the skill includes patterns for a DbClient interface that handles both standard queries and transactional logic within the repository layer.

How does it handle database-agnostic models?

It defines domain-specific interfaces that contain no persistence-related details, ensuring that the rest of your application only interacts with pure TypeScript types.

Does this skill work with specific ORMs?

While it favors a repository pattern with raw SQL mapping for maximum control, the architectural principles can be applied to various database clients like porsager/postgres or pg.

What is the benefit of using this Data Access Layer skill?

It enforces a clean separation of concerns, making your code more maintainable, easier to test, and flexible enough to swap database drivers without rewriting core business logic.

Builds and manages robust, repository-based data access layers for TypeScript and Node.js applications.

关于

This skill automates the creation and maintenance of a decoupled data access layer using the Repository pattern. It ensures your application logic remains independent of specific database implementations by defining DB-agnostic model interfaces and repository contracts. By centralizing SQL queries and mapping logic within dedicated repositories and using dependency injection for database clients, it simplifies testing, improves code maintainability, and makes swapping database providers—such as moving from pg to porsager/postgres—a seamless process.
