Ecosystem

that-depends is part of the modern-python organization — a collection of open-source templates and libraries for production-ready Python applications.

Newer DI framework: modern-di

If you're starting a new project, consider modern-di — the newer DI framework from the same author. It ships as a small core plus a family of thin framework adapters, in contrast to that-depends's batteries-included approach.

that-depends remains actively maintained. The migration guide on the modern-di docs walks through the API differences if you want to move an existing project across.
