In today’s fast-paced development landscape, creating robust and efficient APIs is crucial for building scalable and maintainable applications. FastAPI, a modern Python web framework, coupled with MongoDB, a NoSQL database, offers a powerful combination for seamless RESTful API development.

In this article, we’ll dive into the practical aspects of implementing a RESTful API with FastAPI and MongoDB, providing code examples and insights to help you streamline your development workflow.

Getting Started with FastAPI

FastAPI stands out for its performance, simplicity, and automatic documentation generation. To kick things off, make sure you have Python installed, and then install FastAPI and Uvicorn (ASGI server) using pip:

pip install fastapi uvicorn

Now, let’s create a basic FastAPI app to get a feel for its simplicity. Create a file named main.py and add the following code:

from fastapi import FastAPI

app = FastAPI()

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