litestar-autowire

litestar-autowire 0.2.0 discovers Litestar controllers and event listeners from domain packages. It can also load optional integration modules without turning application setup into a central list of every domain component.

Use Autowire when the project already groups features into stable Python packages. Keep manual Router and plugin composition when the app is small, route registration is intentionally explicit, or packages do not follow a consistent convention.

Code Style Rules

• Configure dotted package roots with domain_packages.
• Import public APIs from litestar_autowire.
• Keep controllers and listeners in their owning domain package.
• Keep route handlers and listeners async when they perform I/O.
• Configure third-party loaders via integrations (DishkaIntegration(), QueuesIntegration()).
• Configure Dishka and Litestar Queues separately; Autowire only discovers or wraps their domain-owned components.
• Keep runtime-inspected controller imports (FromDishka, NamedDependency, Request, injected service types, and DTOs) at module top-level with # noqa: TC001, TC002 (or "**/controllers.py" = ["TC001", "TC002", "TC003"] in Ruff per-file-ignores) when from __future__ import annotations is active.
• Call clear_autowire_cache() when tests create, replace, or remove modules.

Quick Reference

Regular packages and PEP 420 namespace packages are supported. Autowire checks the configured root and each direct child package. Read Discovery before changing module conventions or debugging a missing component.
