WePositive DI

WePositive DI is a small dependency injection layer on top of dependency-injector with FastAPI-style dependency declarations that can be used in any Python application.

It has two parts:

Part	Purpose
Dependency injection	Register sync, async, factory, singleton, and context manager providers, then inject them with Depends[...].
Context management	Store typed Pydantic context objects in an async-safe storage backend and expose the storage through DI.

Why use it?

• Use the same dependency patterns in scripts, workers, web apps, and tests.
• Keep dependencies explicit without passing every object through every call.
• Manage resources with context manager providers that clean up after each call.
• Swap implementations with provider overrides for tests or deployment-specific storage.

Read Getting Started for a short working example, then use Providers for the full provider matrix and API Reference for exact signatures.
