ajv-formats-draft2019

Plugin for AJV (v1.6.1) adding draft2019 JSON Schema string formats: iri, iri-reference, idn-email, idn-hostname, and duration. Released regularly, supports cherry-picking formats for smaller bundles. Key differentiator: fills formats AJV core omits; provides internationalized formats for email and hostnames with RFC compliance (RFC 1123 vs older RFC 1034). Supports both patching an AJV instance or passing formats directly to constructor. Lightweight with minimal dependencies.
