CarapaceFramework-agnostic DTOs for PHP

Lightweight, immutable, strictly typed Data Transfer Objects with attribute-driven mapping

Immutable DTOs

Define immutable data objects by extending the ImmutableDTO base class. Properties are initialized via constructor promotion.

Attribute-Driven Mapping

Use PHP attributes like CastWith, MapFrom, MapTo, and Hidden to control how data is hydrated, transformed, and serialized with minimal boilerplate.

Framework-Agnostic

Works in Laravel, Symfony, or plain PHP projects. Carapace is a lightweight library with no external dependencies, making it easy to integrate into any PHP 8.2+ project.

Strictly Typed

Leverage PHP's type system to create well-defined, predictable data structures. Carapace encourages type safety.

Simple, Expressive API

Create, hydrate, and transform DTOs with a clean, intuitive API. Carapace makes working with DTOs a pleasure, reducing boilerplate and increasing productivity.
