It lets you create a registry object, decorate classes to register them under string keys, and then instantiate those classes by key lookup. The pattern is useful for plugin systems, service locators, and any scenario where you need to dynamically select and instantiate classes at runtime based on configuration or user input.\n\nThe package supports advanced features including passing constructor arguments, automatic registration of non-abstract classes, and integration with setuptools entry points to allow third-party libraries to extend your registries. With zero runtime dependencies and active maintenance, it's a straightforward tool for implementing these patterns without external complexity.","worth_installing":"Yes. The package is actively maintained, has zero security vulnerabilities, imposes no dependency overhead, and cleanly solves a common architectural problem. It is worth installing if you need to implement registry or factory patterns in your application. The MIT license removes any legal friction. The only constraint is the Python 3.12 or later requirement."},"id":"phx-class-registry","links":{"html":"https://skillfed.io/packages/phx-class-registry","md":"https://skillfed.io/packages/phx-class-registry.md","pypi":"https://pypi.org/project/phx-class-registry/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-12","license_spdx":"MIT","license_treatment":"permissive","name":"phx-class-registry","python_support":"supports_current","summary":"Factory+Registry pattern for Python classes"},"popularity":{"monthly_downloads":145901,"position":11114,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"5.2.2"}
