simple_module_core

Module-system primitives for the simple_module framework — a modular-monolith for Python/FastAPI where each feature is a plugin package discovered at boot.

This package defines ModuleBase, the ModuleMeta descriptor, the discover_modules() entry-point loader, topological dependency sorting, event bus primitives, and the diagnostic codes (SM001–SM021) used by make doctor.

Install

pip install simple_module_core

You usually don't install this directly — it's pulled in by simple_module_hosting and every simple_module_* module.

What it provides

  • ModuleBase — the subclass every module extends to opt into lifecycle hooks.
  • ModuleMeta — required meta = ModuleMeta(name=..., depends_on=...) attribute on each module.
  • discover_modules() — loads all [project.entry-points.simple_module] modules, topologically sorts by depends_on.
  • Diagnostic registry — SM001 missing meta, SM003 orphan page, SM008 duplicate name, SM009 framework→plugin coupling violation, and the rest of the SM0xx set through SM021.
  • Tiny event-bus (pyee) for decoupled module-to-module communication.

Usage

# modules/orders/orders/module.py
from simple_module_core import ModuleBase, ModuleMeta


class OrdersModule(ModuleBase):
    meta = ModuleMeta(name="orders", depends_on=["users"])

    def register_routes(self, api_router, view_router):
        from .endpoints import api, views

        api_router.include_router(api.router)
        view_router.include_router(views.router)

And in pyproject.toml:

[project.entry-points.simple_module]
orders = "orders.module:OrdersModule"

The host's discover_modules() call picks this up automatically at boot.

Depends on

  • fastapi, pydantic, pydantic-settings, pyee, babel, packaging
