Umbraco Context API

What is it?

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.

Documentation

Always fetch the latest docs before implementing:

• Main docs: https://docs.umbraco.com/umbraco-cms/customizing/foundation/context-api
• Consume Context: https://docs.umbraco.com/umbraco-cms/customizing/foundation/context-api/consume-a-context
• Provide Context: https://docs.umbraco.com/umbraco-cms/customizing/foundation/context-api/provide-a-context
• Foundation: https://docs.umbraco.com/umbraco-cms/customizing/foundation

Workflow

1. Fetch docs - Use WebFetch on the URLs above
2. Ask questions - Need to consume or provide? Which context? One-time or subscription?
3. Generate code - Implement context consumption or provision based on latest docs
4. Explain - Show what was created and how contexts flow
