Best Practice to Make HTTP Request in FastAPI Application

In this video, you'll learn how to make highly available FastAPI endpoints using asynchronous HTTP requests.

We'll cover:

Why standard requests library blocks the event loop
Introducing httpx for asynchronous requests in FastAPI
3 Best Practices:
Creating an AsyncClient with context manager (basic approach)
Using a dependency for cleaner code
Application-wide AsyncClient for efficiency (with trade-offs)

Optimize your FastAPI application for maximum responsiveness!

thx bro! so useful material, keep going

Hello! Thank you for the video! Could you tell me how to measure the request (in your video it’s about 300ms)? Using a decorator? If so, I tried it, but it didn’t help, because time information is simply not displayed in the logs. I would like this information to be absorbed and for me to see a clear difference in the use of reguess and nttpx. I can’t leave a comment with a link to pastebin because youtube deletes such comments

dont we have to enable the 68 no line? "app = Fastapi(lifespan=lifespan)" ?

this is not about FastApi, its about sync functions and async functions so just dont use sync functions in async functions if sync one is takes a lot of time.
