Overview ¶
Package querylimits provides stable core query-parameter guardrail middleware.
Use New with Options when handlers need bounded query parameter counts, key lengths, value lengths, and pagination limit values before application parsing. Middleware and Handler expose the same guardrail for ports.Middleware wiring or direct net/http usage.
Invalid query shapes fail with Problem Details 400 responses and do not reach the wrapped handler. The package does not parse business filters or database queries; use queryparams for typed collection-query parsing after these size and limit checks pass.
