Requests
The elegant, human-friendly HTTP library that made Python's most-used API for talking to the web.
Pydantic
Data validation and settings management using Python type hints, backed by a Rust core.
pytest
The Python testing framework that makes writing small tests easy and scales to complex functional test suites.
webpack
A static module bundler that builds a dependency graph of your project's modules and packages them into optimized browser bundles
HTTPX
A next-generation HTTP client for Python with sync, async, and HTTP/2 support
Uvicorn
A lightning-fast ASGI server for Python, built on uvloop and httptools.
