Generate Python FastApi Rest Client & Server

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints. It is also well-documented and has a fast-growing community, making it a popular choice for building RESTful APIs.

In this article, we will explore how to generate a Python FastAPI REST client and server using the open-source library.

Installing FastAPI

To get started with FastAPI, you can install it using the following command:


pip install fastapi


Generating FastAPI Server

To generate a FastAPI server, you can create a Python file and define your endpoints using the FastAPI decorator:


from fastapi import FastAPI
app = FastAPI()

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


You can then run your server using the following command:


uvicorn app:app --reload


Generating FastAPI Client

FastAPI also provides a convenient way to generate a client for your server using the openapi_client package. You can use the following command to generate a client for your server:


pip install openapi_client


After installing the openapi_client package, you can use it to generate a client for your FastAPI server using the OpenAPI specification file.

Conclusion

FastAPI is a powerful and modern web framework for building RESTful APIs with Python. It provides a convenient way to generate both the server and client for your APIs, making it easier to develop and maintain your API infrastructure.

By following the steps outlined in this article, you can quickly generate a Python FastAPI REST client and server, allowing you to build and test your APIs with ease.
