1. orjson

   1 22 6,975 8.2 Python

   Fast, correct Python JSON library supporting dataclasses, datetimes, and numpy

   

   Project mention: Web scraping of a dynamic website using Python with HTTP Client | dev.to | 2024-09-28

   The library already has support for an HTTP client that allows bypassing Cloudflare - CurlImpersonateHttpClient. Since we have to work with JSON responses we could use parsel_crawler added in version 0.3.0, but I think this is excessive for such tasks, besides I like the high speed of orjson.. Therefore, we'll need to implement our crawler rather than using one of the ready-made ones.
