    Project mention: Is Rust Web Yet? | | 2022-04-16

    Mypy together with this plug-in gives you typing for django.

  • classes

    Smart, pythonic, ad-hoc, typed polymorphism for Python

    Project mention: Typeclasses in Python | | 2021-07-08

    Today I am going to introduce a new concept for Python developers: typeclasses. It is a concept behind our new dry-python library called classes.

  • starlite

    Light, Flexible and Extensible ASGI API framework

    Project mention: What new in Starlite 1.1 | | 2022-02-14

    One feature you could actually contribute to is this:

  • nitpick

    Enforce the same settings on multiple projects

    Project mention: Creating A Modern Python Development Environment | | 2022-04-12

    It can become tedious maintaining configurations across projects, especially since EditorConfig, pytest-cov, flake8, Mypy and pre-commit all require configuration files. Nitpick is a tool and flake8 plugin that enforces the same configurations across multiple language-independent projects, automating this tedious configuration.

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

  • cachew

    Transparent and persistent cache/serialization powered by type hints

  • Wagtail-Pipit

    Pipit is a Wagtail CMS boilerplate which aims to provide an easy and modern developer workflow with a React-rendered frontend.

    Project mention: Headless Wagtail, what are the pain points? | | 2022-02-25

    To better understand how to set up such a project I went through The Definitive Guide to Next.js and Wagtail by Michael Yin and this boilerplate repo by Frojd. I recommend you checkout the repo first and get the book only if you need further explanations.

  • pfun

    Functional, composable, asynchronous, type-safe Python.

    Project mention: good examples of functional-like python code that one can study? | | 2021-06-29

    Another examples: pfun - stuff you'd find in FP language, but in Python (like using monads for effects)

  • lagom

    📦 Autowiring dependency injection container for python 3 (by meadsteve)

  • pandas-stubs

    Pandas type stubs. Helps you type-check your code.

    Project mention: How can I fix LSP showing as ERRORS for python library sentence? | | 2021-08-19

    I haven't had personal experience with using pandas with pyright but check out stubs for pandas. Maybe something like this could help.

  • mmpm

    MagicMirror Package Manager

    Project mention: Willing to pay for help | | 2021-11-17
  • phantom-types

    👻 Phantom types for Python

  • docopt-ng

    Humane command line arguments parser. Now with maintenance, typehints, and complete test coverage.

    Project mention: To that guy who told me about argparse | | 2022-02-03

    Note, the python source of docopt seems to have been effectively abandoned, so a better bet these days might be docopt-ng from the jazzband coop

  • flake8-typing-imports

    flake8 plugin which checks that typing imports are properly guarded

  • typeforce

    Make mypy more effective

    Project mention: typeforce: Make mypy more effective | | 2022-05-03
  • openapi-type

    OpenAPI represented as a Python type. Use it to parse specifications written in JSON and YAML formats.

  • patina

    Project mention: Show HN: Patina – Python Adaptations of Rust's Option, Result, and HashMap | | 2021-05-27
  • django-multiple-schemas

    Sample project that describes how you can handle schema within your Django application.

    Project mention: Production-ready shell startup scripts: The Set Builtin | | 2021-05-27

    When you build an application and make it available through container technology, either you have an ENTRYPOINT or CMD instructions at the end of its Dockerfile. Depending on which framework you're using and some requirements you have, sometimes it's better to have a bash script responsible for running your project. When it's available, generally, you'll see a bunch of commands that are executed, like the following script I created for the project Django Multiple Schemas:

  • orinoco

    Functional composable pipelines allowing clean separation of the business logic and its implementation
