To share state between Umbraco backoffice extensions, implement a global context that provides a persistent, session-scoped shared state and API surface for cross-extension coordination. This prevents logic duplication across multiple plugins.

A global context in the Umbraco backoffice is a persistent, session-scoped shared state and API surface. It enables centralized service state and shared functions available throughout the session for cross-extension coordination.

To register a global context extension manifest in Umbraco, generate a context token and implementation class, then publish the globalContext extension via the package manifest so backoffice consumers can reliably access the shared state.

Yes, you need a context token to implement type-safe state in Umbraco. Creating the context token and a global context class follows Umbraco’s extension patterns, ensuring shared session-level state is type-safe across consumers.

Use a global context instead of local component state in Umbraco when multiple UI components or plugins need to read and update the same shared session-level state, requiring cross-extension coordination and centralized service state.
