55-58: LGTM! Consider adding explicit return type.The implementation is clean and effectively serves its purpose of forcing a re-render.
Consider adding an explicit return type for better type safety:
-function useForceRedraw(){ +function useForceRedraw(): () => void {
219-221: LGTM! Consider improving the comment clarity.The solution effectively addresses the context update issue while avoiding render loops.
Consider improving the comment clarity:
-//force rerender because chaging a ref does not update the context -//changing provided to a useState will result in a rendering loop because of the useLayoutEffect below +// Force re-render when context ref changes, as ref updates don't trigger re-renders +// Note: Using useState here would create an infinite loop due to the useLayoutEffect belowsrc/core/component.test.tsx (1)
247-251: LGTM! Fix empty object type.The Component1 changes effectively test the readonly prop behavior.
Replace the empty object type with a proper interface as flagged by static analysis:
-const Component2 = createCesiumComponent<string, {}>({ +const Component2 = createCesiumComponent<string, Record<string, never>>({

169-169: LGTM! Verify impact of context dependency.
The addition of ctx to dependency arrays ensures proper reactivity to context changes.
Let's verify that the context dependency doesn't cause unnecessary re-renders:
Also applies to: 234-234, 276-276, 317-317
✅ Verification successful
LGTM! Context dependency is correctly implemented
The ctx dependency in the dependency arrays is necessary and properly used:
updatePropertiesusesctxin theupdatecallback and event manager operationsmountusesctxfor element creation and context provisionunmountusesctxfor cleanup and event management- The effect hook properly tracks context changes for updating properties
The context changes will not cause unnecessary re-renders because:
- Context is only used for essential operations (creation, updates, and cleanup)
- Updates are guarded by shallow prop comparison (
shallowEquals) - Context updates are batched through React's scheduling

267-282: LGTM! Test coverage is comprehensive.
The test assertions effectively verify both the initial context state and updates when readOnlyProp changes.
Changing a read only prop recreates an component. But if the component provides values with a context the context did not get updated . Additionally if the context changes all componets below need to be updated to work with the new context see
This pr adds a forced redraw (change of dumy state) after provided.current gets changed.
I tried changing provided to a useState but this resultet in an redraw loop ( provided changes -> useCallbacks need to update with the provided values -> layoutEffect reexecutes and remounts componets -> provided changes).
The solution feels kind of hacky but i didn't want to rewrite the core logic with all the useRefs. This could leed to more bugs, but i am open to suggestions/alternative solutions. This forced Redraw should not leed to Problems. The mount callbak only gets called once on initial draw and once after a readonly prop changes.
To update all components using the context it was added to the dependency array. This implys that all components using the context get remounted by the useLayoutEffect (callbacks change, layoutEffect gets reexecuted). This fixes
I added a test to check for correct context after a readonly prop changes
