Laravel Argonaut Dto Laravel Package

yorcreative/laravel-argonaut-dto

Lightweight, composable Laravel DTO package to transform arrays/objects/collections into typed, validated data objects. Supports deep nested casting, type-safe conversion, Laravel Validator rules, explicit attribute priority, clean toArray/toJson serialization, and immutable readonly DTOs.

Product Decisions This Supports

Supports structured DTO patterns for type-safe data handling, reducing manual serialization/validation code.
Enables informed build vs buy decisions by providing a maintainable, Laravel-integrated solution with reusable traits for extensibility.
Critical use cases: API development, command handlers, and data transformation layers requiring strict typing, enum support, and immutable data structures.

When to Consider This Package

Adopt when needing immutable DTOs (e.g., CQRS), BackedEnum casting, or serialization helpers like only(), except(), and merge().
Ideal for Laravel projects using PHP 8.0+ and prioritizing code quality via PHPStan.
Avoid if requiring complex nested DTOs beyond basic structures, non-Laravel environments, or if legacy PHP versions (<8.0) are mandatory.

How to Pitch It (Stakeholders)

Executives: "Reduces development time by eliminating boilerplate validation/serialization code, minimizes runtime errors through strict typing, and ensures data integrity with immutable DTOs—accelerating feature delivery while cutting maintenance costs."
Engineering: "Refactored traits (HasCasting, HasSerialization, HasValidation) improve code reuse and maintainability. BackedEnum support and serialization helpers simplify data handling in APIs, while PHPStan level 5 and CI updates ensure robust, future-proof code quality."
