How to setup FastApi

Description

The tutorial guides you through the essential steps of initializing a FastAPI project, including: Environment Setup: Creating a dedicated project directory and setting up a Python virtual environment to manage dependencies. Dependency Management: Using a requirements.txt file to install FastAPI and Uvicorn (the ASGI server used to run the application). Coding the API: Creating an application instance and defining a basic "root" route that returns a JSON response. Running the Server: Launching the development server with the --reload flag to see changes in real-time. Key Timestamps [00:00] - Introduction to the FastAPI setup process.
