FastAPI and Uvicorn Logging

When running FastAPI app, all the logs in console are from Uvicorn and they do not have timestamp and other useful information. As Uvicorn applies python logging module, we can override Uvicorn logging formatter by applying a new logging configuration.

Meanwhile, it's able to unify the your endpoints logging with the Uvicorn logging by configuring all of them in the config file log_conf.yaml.

Before overriding:

uvicorn main:app --reload

Functor and monad examples in plain Java

이 글은 우리가 쓴 책, 'Reactive Programming with RxJava' 의 부록이었다. Reactive programming과 관련이 깊은 주제긴 하지만 모나드를 소개한다는 게 책과 썩 어울리지는 않았다. 그래서 나는 따로 블로그에 올리기로 했다. 프로그래밍을 다루는 블로그에서 *"반은 맞고 반은 틀릴 지 모르는 나만의 모나드 설명"*이란 것이 새로운 *"Hello World"*라는 점을 나도 잘 안다. 하지만 이 글은 펑터(functor)와 모나드(monad)를 자바 자료 구조와 라이브러리라는 각도에서 바라보고 있으며, 이는 공유할 정도의 가치는 있을거라 생각했다.
