What it is and what it does
azurefunctions-extensions-base is a foundational library for the Azure Functions Python worker that enables custom extensions to recognize and bind to SDK types and HttpV2 types. It is not designed for direct use; instead, it serves as the base layer for specialized extension packages that add specific bindings (blob storage, Cosmos DB, Event Hubs, Service Bus) and protocol handlers (FastAPI over HTTP).
The package has no runtime dependencies and installs with low friction. It supports Python 3.8 and later, with active maintenance as of mid-2026. Developers should install this only as a transitive dependency of an extending package, not directly in application code.
Use it for
- Building custom Azure Functions extensions that need to bind to Azure SDK types.
- Extending Azure Functions with new protocol handlers beyond standard HTTP.
- Integrating FastAPI or other frameworks as Azure Functions bindings.
- Adding support for Azure services (blob, Cosmos DB, Event Hubs, Service Bus) as function triggers or outputs.
