What query operators does this skill support?

The skill supports a wide range of operators including equality (eq), inequality (ne), comparison (gt, gte, lt, lte), set inclusion (in), and pattern matching (like).

Does it support sorting by multiple fields?

Yes, the system allows for sorting by multiple fields simultaneously, including support for ascending and descending directions using prefix notation like '-price'.

Can I use this with any database?

While the implementation example uses Node.js patterns, the logic for query parameter parsing and validation can be adapted for any SQL or NoSQL database environment.

How does this skill handle API security?

It emphasizes security by implementing field whitelisting, input type validation, and complexity limits to prevent SQL or NoSQL injection attacks.

Is this skill compatible with Claude Code CLI?

Yes, this is a specialized skill designed to enhance Claude Code's ability to generate production-ready backend code within your terminal.

API Development

Builds flexible, secure API filtering and sorting systems with query parameter parsing and validation.

About

This skill empowers developers to implement robust search and discovery features by providing a standardized pattern for handling complex query parameters in RESTful APIs. It automates the creation of dynamic query systems using Node.js, supporting advanced operators like greater-than and less-than while prioritizing security through field whitelisting and input validation. It is particularly useful for building data-heavy applications, admin dashboards, or e-commerce search endpoints that require efficient and safe data retrieval from SQL or NoSQL databases.
