Components Contrib

The purpose of Components Contrib is to provide open, community-driven, reusable components for building distributed applications. These components are being used by the Dapr project, but are separate and decoupled from it.

Using components developers can interact with bindings, state stores, messaging systems and more, without caring about the underlying implementation.

Available component types:

For documentation on how components are being used in Dapr in a language/platform agnostic way, visit Dapr Docs.
