Type Info Laravel Package

Product Decisions This Supports

• Build vs. Buy: Buy to avoid reinventing type resolution logic, especially for projects leveraging PHP 8+ features (enums, generics, attributes). Reduces maintenance overhead and aligns with Symfony’s battle-tested ecosystem.

  • Dynamic Validation: Enforce runtime type checks in APIs (e.g., Symfony Serializer, API Platform) without manual validation logic.
  • Schema-Driven Development: Automate OpenAPI/GraphQL schema generation by resolving PHP types to standardized formats (e.g., Type::generic(Collection::class, Type::int()) → Collection<int> in OpenAPI).
  • Legacy Code Modernization: Infer PHPDoc types for static analysis tools (PHPStan, Psalm) or IDE hints, improving DX without manual annotation.
  • Type-Safe Middleware: Build middleware to validate request/response types dynamically (e.g., reject null where Type::nullable(Type::int()) is expected).
  • Template Engines: Resolve template variables (e.g., Twig) to enforce type safety in rendered output (e.g., Type::fromValue($variable)).

• Roadmap Priorities:

  • Phase 1: Integrate into existing validation/serialization pipelines (e.g., Symfony Serializer) to standardize type resolution.
  • Phase 2: Extend to schema generation tools (e.g., NelmioApiDoc) for automated API documentation.
  • Phase 3: Use for runtime type enforcement in microservices (e.g., reject malformed payloads early).

When to Consider This Package

• Adopt if:

  • Your project uses PHP 8+ (enums, generics, attributes) and needs runtime type introspection.
  • You’re building APIs/serializers requiring consistent type resolution (e.g., Symfony Serializer, API Platform).
  • You need to generate schemas (OpenAPI/GraphQL) from PHP types without manual mapping.
  • You’re modernizing legacy code and want to infer PHPDoc types for static analysis tools.
  • You require dynamic type validation (e.g., middleware, event listeners) without custom reflection logic.

• Look elsewhere if:

  • Your stack is pre-PHP 8 (limited support for enums/generics).
  • You need compile-time type checking (use PHPStan/Psalm directly).
  • Your use case is simple (e.g., basic type hints without generics/nullability).
  • You’re already using a dedicated schema tool (e.g., OpenAPI Generator) with built-in type resolution.

How to Pitch It (Stakeholders)

For Executives: "Symfony’s TypeInfo component lets us automate type resolution across our codebase—reducing bugs in APIs, serializers, and schemas while cutting manual effort. For example, we can dynamically validate request/response types in real-time (e.g., reject null where int is expected) and generate OpenAPI docs from PHP types without manual mapping. This aligns with our tech debt reduction goals and improves developer productivity by 30%+ for type-heavy workflows."

For Engineers: *"This package gives us a reliable, Symfony-backed way to resolve PHP types at runtime—supporting generics, enums, and nullability out of the box. Key wins:

• Validation: Enforce types in Symfony Serializer/API Platform without custom logic.
• Schemas: Auto-generate OpenAPI/GraphQL types from PHP classes (e.g., User[] → array[User]).
• Legacy Code: Infer PHPDoc types for PHPStan/Psalm to improve IDE hints.
• Performance: Built-in caching (TypeContextFactory) avoids redundant reflection calls. No need to build or maintain our own type resolver—it’s production-ready and integrates seamlessly with Symfony’s ecosystem."
