Building an API with FastAPI

• httpie

  116 31,842 6.6 Python

  🥧 HTTPie CLI — modern, user-friendly command-line HTTP client for the API era. JSON support, colors, sessions, downloads, plugins & more. (by httpie)

  

At first, I saved a sample of the trending repositories HTML to avoid sending dozens of requests to Github. I use HTTPie as HTTP client to perform requests via the terminal.

• k6

  20 23,316 9.6 Go

  A modern load testing tool, using Go and JavaScript - https://k6.io

  

But how does the app perform? Professional tools like ApacheBench or k6 are commonly used to perform load testing, but in this case I wrote a small asynchronous script to bomb the application with requests. Comparing the performance of sync or async web apps without using async requests would be nonsense. I'll call it requests_benchmark.py and place it within the tests/ folder. Be aware that this is a rough comparison, I just want to illustrate the difference between synchronous and asynchronous code.

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• requests

  87 51,359 8.4 Python

  A simple, yet elegant, HTTP library.

  

I executed the script 3 times making 20 requests on each execution. Ok now lets replace the synchronous requests library by the asynchronous aiohttp library. Furthermore, we add the async/await keywords on the right positions. Our final code will look like this:

• AIOHTTP

  23 14,547 9.7 Python

  Asynchronous HTTP client/server framework for asyncio and Python
