DI components of Web frameworks

Several modern Python web frameworks include DI components, including:

• FastAPI -> Dependencies - First Steps.
• Litestar -> Dependency Injection.
• Sanic -> https://sanic.dev/en/plugins/sanic-ext/injection.html.
• Xpresso -> di (see above)
• Blacksheep -> Rodi (see above)
• Aiodine (dead, see below) was the DI framework for the Bocadillo project (also dead)

Archived or unmaintained DI frameworks

• Serum ★84: "Dependency injection framework for Python 3.6" (unmaintained)
• Aiodine ★54: "Async-first Python dependency injection library" (unmaintained)
• Wiring ★27: Architectural foundation for Python applications. (Unmaintained).

Integration with web frameworks

• Flask-Injector ★246: Adds Injector support to Flask.
• Pyramid-Wiring ★0: integration of Wiring and Pyramid (unmaintained).
