Leverages the FastAPI lifespan pattern to efficiently initialize resources

Original Description

Description: This video tackles the common issue in FastAPI applications where resources like database connections and LLM clients are created on every request. We explore how to leverage `lifespan` to efficiently initialize these resources once at app startup and properly clean them up on shutdown, optimizing your `python` application's performance. Learn `fastapi` and streamline your `coding` practices for more robust and scalable solutions. Hashtags: #FastAPI #Lifespan #StartupShutdown #AIBackend #Python
