How do I resolve multiple providers of the same class type?

You can use the 'qualifier' parameter in the @provider decorator and then use the Annotated[Type, Qualifier('name')] syntax when injecting the dependency.

How do I mock dependencies for unit testing in myfy?

The framework provides an 'override' context manager that allows you to temporarily replace a specific provider with a mock or alternative instance within a code block.

Can a Singleton depend on a Request-scoped provider?

No. SINGLETON providers can only depend on other singletons. This rule prevents memory leaks and is enforced at compile time to ensure architectural integrity.

What dependency scopes are supported in myfy?

myfy supports three scopes: SINGLETON (application lifetime), REQUEST (per HTTP request), and TASK (per background task execution).

Desarrollo de API

Manages complex dependency life cycles and injection patterns within the myfy framework.

This skill provides deep domain knowledge for the myfy dependency injection system, enabling developers to build modular and testable Python applications. It covers the implementation of constructor-based DI across three distinct lifecycles: SINGLETON for shared resources, REQUEST for web contexts, and TASK for background workers. By applying this skill, developers can ensure strict architectural boundaries through compile-time scope validation, utilize qualifiers for ambiguous resolution, and implement advanced patterns like the Factory pattern to bridge different scope levels effectively.
