umbraco-context-api

The Context API is Umbraco's communication system that enables extensions to share data and functionality through the component hierarchy without tight coupling. It uses a provider-consumer pattern where parent elements provide contexts that descendant components can access. Contexts cascade down through the DOM tree and use tokens for type-safe access to services like notifications, workspaces, and user information.

Provider: Element that provides context to descendants via provideContext()

Consumer: Element that accesses context via consumeContext() or getContext()
