Instantiator Laravel Package

doctrine/instantiator

Lightweight PHP library to instantiate objects without calling their constructors. Useful for hydrators, serializers, proxies, and testing/mocking. Part of the Doctrine ecosystem; creates instances via reflection while avoiding side effects and required constructor args.

Product Decisions This Supports

  • Enables efficient testing by creating mock objects without constructor side effects, reducing test setup complexity
  • Supports ORM and serialization workflows where hydrating entities without executing constructor logic is required
  • Eliminates the need for custom in-house solutions for object instantiation, reducing maintenance overhead
  • Facilitates building robust frameworks that handle edge cases (e.g., final classes, private constructors) consistently across PHP versions

When to Consider This Package

  • When your project requires object instantiation that bypasses constructors (e.g., testing, proxy generation, hydration)
  • When dealing with classes that have private/protected constructors, final classes, or internal PHP objects
  • When needing a minimal, dependency-free solution with broad PHP version compatibility
  • When integrating with existing tools like PHPUnit, Doctrine ORM, or Symfony where this package is commonly used

When to Look Elsewhere:

  • If your application has no need for constructor-bypassing instantiation (e.g., simple object creation with public constructors)
  • When using a framework that already provides built-in functionality for these scenarios (e.g., Symfony's PropertyInfo component for some hydration tasks)
  • If your security policies prohibit third-party dependencies, though this package's MIT license and minimal footprint make it low-risk
  • For projects using non-PHP environments where this tool is irrelevant

How to Pitch It (Stakeholders)

  • For executives: "This package reduces development time and testing complexity by enabling safe object instantiation without constructor side effects, accelerating feature delivery while minimizing bugs. Its MIT license and widespread adoption in frameworks like Doctrine ensure low risk and high reliability."
  • For engineering: "A lightweight, battle-tested tool for handling edge cases in object creation—like final classes or private constructors—with zero dependencies. Integrates seamlessly into testing, ORM, and serialization workflows, saving weeks of custom code and ensuring consistency across PHP versions."
