What specifically can the Nest.js Expert skill help with?

It provides domain-specific guidance for Nest.js architecture, dependency injection, middleware implementation, database integration (TypeORM/Mongoose), and testing strategies.

Does it support automated testing validation?

Yes, it follows a strict validation sequence of typechecking, followed by unit tests, integration tests, and finally e2e tests using Jest and Supertest to ensure code reliability.

How does this skill handle circular dependency errors?

It identifies the root cause of the dependency loop and recommends either refactoring shared logic into a third module or correctly implementing forwardRef() on both sides of the relationship.

Can it help with database configuration?

Absolutely. It has specific troubleshooting patterns for TypeORM, Mongoose, and Prisma, including entity configuration, repository patterns, and connection management.

Does it recommend switching to other experts?

Yes, if a problem is strictly related to pure TypeScript types, frontend React issues, or low-level Node.js runtime errors, it will proactively suggest switching to a more specialized subagent.
