Filtering & Sorting

Summary

Letting API consumers narrow and reorder result sets via query parameters — a core expectation for any listing endpoint in a real API.

• 1Add filter and sort query params to a listing endpoint, validating allowed fields.
• 2Prevent sort-injection by whitelisting sortable columns rather than trusting raw input.
• 3Design a consistent query param convention, e.g. `?sort=-createdAt`, across your API.
