  • APIs in Go with Huma 2.0
    6 projects | dev.to | 6 Dec 2023
    I wound up on a different team with pre-existing Python code so temporarily shelved my use of Go for a bit, and we used Sanic (an async Python framework built on top of the excellent uvloop & libuv that also powers Node.js) to build some APIs for live channel management & operations. We hand-wrote our OpenAPI and used it to generate documentation and a CLI, which was an improvement over what was there (or not) before. Other teams used the OpenAPI document to generate SDKs to interact with our service.

    If you're looking for maximum requests per second you can change the asyncio event loop with one like UVLoop.

    The source code from the project resides in the github, with more than 8.6k stars and 596 forks is a very popular github, but no new releases are made since 2018, looks pure much not maintained anymore, no PR's are accepted no Issues are closed, still without windows or macOS Silicon, or PyPy3 support. Japronto it self uses uvloop with more than 9k stars and 521 forks and different from japronto is seems to be well maintained.
  • Modern Python Performance Considerations

    If you are building server-side applications using Python 3 and async API and if you didn't use https://github.com/MagicStack/uvloop, you are missing out on performance big time.

    Also, if you happen to build microservices, don't forget to try PyPy, that's another easy performance booster (if it's compatible to your app).

  • SearX On Windows: A Short(ish) Tech Journey
    3 projects | /r/u_SyntaxAerror | 17 Apr 2022
    And so I did some searching, and found that SearX isn't officially supported on Windows. Not to be deterred, I did another quick search and found that with pip and/or docker, you should be able to install SearX straightforwardly on Windows. After trying this for a bit, I realized that uvloop, a (questionably optional dependency of SearX) is not supported on Windows. I tried a couple things to get it to work, but they didn't end up working for me either through user error, ignorance, or plain old not working.

    they also wrote uvloop [0] which is fantastic and advances the cutting edge of what can be done with modern asyncio-based Python. I saw a ~3x improvement in the throughput of a microservice I wrote when I first tried it out years ago. currently at $dayjob we just use it by default in every Python service, whether or not we expect that service to be performance-critical.

  • How does asynchronous code work in programming languages?
    2 projects | /r/ProgrammingLanguages | 10 Jan 2022
    If you manage to grok how uvloop works as well as Python's default asyncio loop scheduler, you'll understand this style. It is not by itself a parallelism enabler, but network I/O the coroutines triggered would run in parallel nevertheless, though CPU bound computations would not by default.

    Take a look at these guys: https://github.com/MagicStack They are a consultancy that obviously can make good stuff, their libraries are widely used by the Python community. This is how I would monetize your library honestly. It is a source of trust that can unlock other opportunities that would be much harder to obtain without it.

    Nice ! What about python with the free asyncio upgrade https://github.com/MagicStack/uvloop ?
