Episode notes
PyX Middleware For Reliable Packaging
- PyX is a middleware front-end to PyPI that solves packaging and build reliability problems.
- It targets reproducible builds, private registries, and easier installs for heavy packages like GPU libraries.
Use A Managed Registry For Heavy Builds
- Consider using a hosted or mirrored registry for teams to avoid rebuild and authentication headaches.
- A managed registry like PyX can simplify internal package publishing and building complex wheels.
Litestar: Batteries-Included Alternative
- Litestar positions itself between FastAPI and Django by offering more built-in components without forcing Pydantic.
- It supports splitting apps across files and alternative validators like attrs or SQLAlchemy integration.
