Question 1

How do I set up Wireup with Django for dependency injection?

Accepted Answer

Wireup has native Django integration. Create a container with your injectables and use wireup.integration.django.setup to wire it into your project, allowing dependency injection in views and other components without manual instantiation.

Question 2

Wireup vs other Python DI libraries like Injector or dependency-injector?

Accepted Answer

Wireup distinguishes itself with fail-fast startup validation and framework agnosticism, making it more robust for production apps. However, libraries like Injector might offer simpler setups for basic use cases without type-driven requirements.

Question 3

How to override dependencies for unit testing in Wireup?

Accepted Answer

Use the container.override context manager to temporarily replace dependencies. For example, with container.override.injectable(target=Database, new=MockDatabase), you can isolate tests and the original setup is restored automatically.

Question 4

Does Wireup work with async Python and async frameworks?

Accepted Answer

Yes, Wireup fully supports async with async containers and factories. You can define async factories using AsyncIterator for resources needing async cleanup, as shown in the README's async example.

Question 5

How to inject configuration values like API keys with Wireup?

Accepted Answer

Annotate parameters with Inject(config='key') and provide a config dictionary when creating the container. Wireup will inject these values alongside regular dependencies, eliminating the need for manual factory methods.

Question 6

Can I use Wireup without decorating every class with @injectable?

Accepted Answer

Wireup requires @injectable or similar registration for dependency management. However, you can use package-level registration to auto-discover injectables from modules, reducing the need to list each one individually.
