⚡

Zero boilerplate

Declare your constructor properties — hydration, serialization, and validation happen automatically via PHP attributes.

🔒

Fully typed

Readonly properties, nested DTOs, enums, typed collections, and IDE-aware generics out of the box.

🎯

Attribute-driven

#[Cast], #[Rules], #[Flatten], #[Hidden], #[IgnoreIfNull] — all behaviour defined where the property is declared.

🚀

Production-ready performance

Hydration and serialization compile to per-class closures. The file cache plus the sdo-warm CLI give production zero reflection and zero runtime compilation.

🛡️

Secure by default

EncryptedCast uses XSalsa20-Poly1305 authenticated encryption. Validation throws before any hydration occurs.

🔗

Laravel integration

Optional trait adds fromRequest(), fromModel(), and toResponse(). Validation rules run automatically on fromRequest().
