monkay 0.5.2

The ultimate preload, settings, lazy import manager.

Monkay

Monkay is a production-focused module lifecycle toolkit for Python packages. It helps you ship lazy imports, settings loading, extension orchestration, and context-isolated state without fragile import-time side effects.

Why Monkay

Monkay is designed for libraries and applications that need to:

• expose stable public imports while deferring expensive imports,
• run controlled startup preloads and settings evaluation,
• apply pluggable extensions with deterministic conflict behavior,
• isolate mutable state per thread/task for safe tests and request scopes,
• validate module export consistency during development.

Installation

pip install monkay

Runtime requirement: Python 3.10+.

60-Second Example

# yourpkg/__init__.py
from monkay import Monkay

monkay = Monkay(
    globals(),
    lazy_imports={
        "json_dumps": "json:dumps",
    },
)

__all__ = ["json_dumps", "monkay"]

# yourpkg/main.py
from yourpkg import json_dumps

payload = {"status": "ok"}
print(json_dumps(payload))

json_dumps is resolved lazily on first access and cached by default.
