Container

✓ from that_depends import Container

✗ from that_depends import container

Basic setup with container registration and dependency injection.

import os from that_depends import container, Provide, inject class MyService: async def run(self) -> str: return f"Hello {os.environ.get('NAME', 'World')}" # Manually create provider container.register(MyService) @inject async def main(service: MyService = Provide[MyService]): result = await service.run() print(result) # Run import asyncio asyncio.run(main())

Debug

Known issues

gotchaContainer must be imported as `container` (lowercase), not `Container`. The class is not directly exposed.

fix

Use `from that_depends import container` instead of `from that_depends import Container`.

affects: >=3.0.0

breakingIn version 3.0.0, the API was significantly redesigned. Old patterns like `from that_depends import Providers` or `register_singleton` no longer work.

fix

Check the migration guide. Use new `container.register()` and `Provide` annotations.

affects: >=3.0.0

deprecatedThe `@inject` decorator will be removed in a future version. Use `Provider` annotations directly or `container.resolve()`.

fix

Prefer `service = container.resolve(MyService)` over `@inject`.

affects: >=3.5.0

gotchaAsync providers require `await container.resolve()` or `await` in async context. Calling sync resolve on async provider leads to RuntimeError.

fix

Ensure you `await` when resolving async providers, e.g., `service = await container.resolve(MyService)`.
