Type Info Laravel Package

Product Decisions This Supports

• Build vs. Buy: Buy – Avoid reinventing type introspection logic for PHP tooling (e.g., IDE plugins, static analyzers, or validation layers). This package is battle-tested by Symfony and integrates seamlessly with its ecosystem.
• Feature Roadmap:
  • Type-Safe APIs: Use TypeResolver to enforce strict type contracts in API responses or request validation (e.g., OpenAPI/Swagger generation).
  • Dynamic Schema Generation: Power auto-generated schemas for databases, configs, or GraphQL (e.g., resolve ReflectionProperty types to infer schema fields).
  • Debugging/DevTools: Embed type info in error messages or admin panels (e.g., (string) Type::generic(Type::object(Collection::class), Type::int()) → "Collection<int>").
  • PHPStan/Psalm Integration: Standardize type resolution across static analysis tools to reduce false positives/negatives.
• Use Cases:
  • Validation Layers: Replace manual type checks (e.g., is_int($value)) with declarative rules using Type::isSatisfiedBy().
  • Serialization/Deserialization: Infer types for Symfony Serializer or custom JSON/XML mappings (e.g., Type::list(Type::nullable(Type::bool())) for arrays of optional booleans).
  • ORM/Query Builders: Dynamically resolve Doctrine entity property types to optimize queries or generate migrations.
  • Testing Frameworks: Auto-generate test data based on class/property types (e.g., Type::fromValue($entity->getId()) → int).

When to Consider This Package

Adopt if:

• Your PHP project relies on runtime type introspection (e.g., dynamic APIs, plugins, or DSLs).
• You need to normalize types across multiple sources (Reflection, docblocks, raw strings) into a unified model.
• You’re building tooling (linters, IDEs, debuggers) that requires accurate PHP type resolution.
• You’re using Symfony components (Serializer, Validator, PropertyInfo) and want consistency in type handling.

Look elsewhere if:

• You only need basic type checks (e.g., is_array(), gettype()). This package is overkill for simple use cases.
• Your project is JavaScript/TypeScript-heavy—consider zod or io-ts instead.
• You require compile-time type safety (e.g., PHP 8.2+ attributes or #[SensitiveParameter]). Use phpstan/phpstan directly.
• You’re working with non-PHP languages (e.g., Python, Go). This is PHP-specific.

How to Pitch It (Stakeholders)

For Executives: "Symfony’s TypeInfo component lets us automate type safety across our PHP stack—reducing bugs in APIs, validation, and serialization while cutting dev time. For example, instead of manually documenting types in Swagger or validating requests, we can auto-generate schemas from Reflection, ensuring consistency. It’s a low-risk, high-reward investment: MIT-licensed, Symfony-backed, and used in production by thousands of projects. ROI comes from fewer runtime errors and faster tooling development."

For Engineers: *"This is the Swiss Army knife for PHP type introspection. Need to:

• Resolve types from any source (classes, docblocks, strings)?
• Build complex type hierarchies (generics, unions, nullable lists)?
• Validate types programmatically (e.g., Type::isSatisfiedBy(fn (Type $t) => $t->isIdentifiedBy(TypeIdentifier::INT)))?
• Integrate with Symfony’s ecosystem (Serializer, Validator, PropertyInfo)? This does it all without reinventing the wheel. The API is fluent and well-documented, and it’s actively maintained by the Symfony team. Start small: Use TypeResolver to replace manual type checks in your validation layer, then expand to schema generation or debugging tools."*
