Can I add complex filters like date ranges?

Absolutely. The skill includes specific patterns and code templates for implementing minimum and maximum ranges for both dates and numbers.

Does it handle query string type conversion?

Yes, it utilizes Zod's coercion features to properly convert string query parameters into booleans, numbers, or dates automatically.

Are tests included in the implementation?

Yes, the skill provides comprehensive test templates for both schema validation and repository logic to ensure your filters work as expected.

What databases does this skill support?

It provides implementation patterns for both MockDB (in-memory) and MongoDB repositories to ensure consistency across environments.

Does this skill help with database performance?

Yes, it includes a dedicated section on adding MongoDB indexes to ensure that new filters remain performant as your dataset grows.

API開発

Adds custom query parameter filters to entity schemas and repository implementations for robust API search capabilities.

概要

The Add Query Filter skill streamlines the process of extending search and filtering capabilities in TypeScript-based backend services. It provides a structured approach to updating Zod schemas for validation and implementing filter logic across both MockDB and MongoDB repository layers. This ensures consistent behavior between development environments and production databases while maintaining type safety and robust test coverage for complex filtering patterns like date ranges, numeric bounds, and partial text matches.
