@kbn/core-chrome-browser-internal

Implementation of Core's browser-side Chrome service.

Responsibilities

  • ChromeService — lifecycle class (setup / start / stop) that wires up all chrome subsystems and returns the InternalChromeStart contract.
  • State management — observable state for breadcrumbs, badges, nav links, nav controls, help menu, header banner, doc title, project navigation, and more. State is managed in src/state/ and src/services/.
  • createChromeApi — factory that assembles the public ChromeStart / internal InternalChromeStart API surface from the individual state slices.
  • ChromeServiceProvider wiring — start() returns a withProvider(children) function that wraps the React tree with ChromeServiceProvider from @kbn/core-chrome-browser-context.

What does NOT live here

UI components (headers, sidenav, loading indicator, breadcrumbs, etc.) live in @kbn/core-chrome-browser-components. This package is purely state and API — no React rendering.
