What steps do you start with when developing a project using FastAPI?

I am starting the development of a FastAPI project with the following steps:

1. Create a virtual environment to isolate dependencies:

python -m venv venv
source venv/bin/activate  # Linux/macOS
venv\Scripts\activate  # Windows

2. Install FastAPI and the Uvicorn ASGI server:

pip install fastapi uvicorn

3. Create a basic application file, for example main.py:

from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def read_root():
    return {"Hello": "World"}

4. Run the server for testing:

uvicorn main:app --reload

5. Plan the project structure: dividing into routes, models, schemas (Pydantic), databases.

6. Add error handling, documentation, authentication as needed.

Thus, I start with a minimal working application and gradually expand the functionality.
