Introduction

FastAPI is a modern, fast (high-performance) web framework for building APIs with Python 3.6+ based on standard Python type hints. In this article, we will explore how to dynamically serve REST endpoints for database stored procedures with FastAPI.

Step 1: Install FastAPI

To get started, you need to install FastAPI. You can do this using pip:

pip install fastapi

Step 2: Create a FastAPI app

Next, create a FastAPI app in a new Python file:

from fastapi import FastAPI

app = FastAPI()

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

Step 3: Add database connection

You will need to connect your FastAPI app to your database. You can use a library like SQLAlchemy to connect to your database and execute stored procedures.

Step 4: Dynamically serve REST endpoints for stored procedures

Now, you can dynamically serve REST endpoints for your database stored procedures. You can create a new route for each stored procedure you want to expose as a REST endpoint:

from fastapi import APIRouter

router = APIRouter()

@router.get("/users")
def get_users():
    # Call your stored procedure to get users from the database
    users = session.execute("EXEC get_users")

    return {"users": users}

Conclusion

FastAPI makes it easy to create high-performance APIs with Python. By dynamically serving REST endpoints for database stored procedures, you can easily expose your database functionality over HTTP. This can be useful for building microservices, web applications, and more.
