  • GitHub repo pydantic

    Data parsing and validation using Python type hints

    Project mention: Strict Python Function Parameters | | 2022-01-23

    Slightly off-topic, but everyone writing modern Python should be familiar with Pydantic and similar libraries that use type hints for validation and parsing:

    We're using Pydantic for Robusta ( and absolutely love it. You get the best of traditional Python (rapid prototyping and no boilerplate) while still being able to scale your codebase and keep it maintainable. Robusta is the first large project I've written in Python where I'm not encountering type errors at runtime left and right.

  • GitHub repo jsonparser

    One of the fastest alternative JSON parser for Go that does not require schema

    Project mention: Whats the fastest JSON unmarshaling package as of right now? | | 2021-11-02

    If you don't know the schema or you only need to access one or two fields in a much larger JSON object, I would recommend as it provides an easy API to access specific values without fully unmarshaling. This is an unusual use case though, 9 times out of 10 I would tend to use easyjson.

  • GitHub repo mercury-parser

    📜 Extract meaningful content from the chaos of a web page

    Project mention: Build your self-hosted Evernote | | 2022-01-06
