Fastapi Injectable

Here is a rewritten version of the text in a more readable and concise format:

Introduction

fastapi-injectable is a Python library that provides a simple way to manage dependencies in FastAPI applications. It allows you to define dependencies as functions or classes, which can be used throughout your application.

Key Features

• Dependency Injection: Define dependencies as functions or classes, which can be injected into other components.
• Fresh Dependencies per Message: Each message gets a fresh set of dependencies through _init_as_consumer().
• Proper Resource Management: Dependencies with cleanup needs (like database connections) are properly handled.
• Graceful Shutdown: setup_graceful_shutdown() ensures resources are cleaned up on program termination.

Real-world Examples

You can find real-world examples of using fastapi-injectable in various scenarios, including processing messages by background worker and resource cleanup. These examples demonstrate how to handle complex dependency trees, resource management, and mixing sync/async code.
