Type stubs for singleton_decorator

types-singleton-decorator

Type stubs for the singleton_decorator package to provide proper type hints and fix Pylance type checking issues.

Problem Solved

When using the singleton_decorator decorator, Pylance shows the error:

Expected class but received "_SingletonWrapper" PylancereportGeneralTypeIssues

This package provides proper type stubs to resolve this issue and ensure your IDE understands that decorated classes remain classes.

Installation

Install using pip:

pip install types-singleton-decorator

Or using uv:

uv add types-singleton-decorator

Usage

Once installed, the type stubs will automatically be picked up by your type checker (Pylance, mypy, etc.). No additional configuration is needed.

Your singleton decorators will now have proper type support:

from singleton_decorator import singleton

@singleton
class MyClass:
    def __init__(self, value: str):
        self.value = value
    
    def get_value(self) -> str:
        return self.value

# This will now have proper type hints
instance = MyClass("hello")  # Type: MyClass, not _SingletonWrapper
print(instance.get_value())  # Pylance understands this method exists

What's Included

This package provides type stubs for:

• @singleton decorator
• SingletonMeta metaclass (if used)
• Proper preservation of class types and methods

Requirements

• Python >= 3.8
• The original singleton_decorator package
