71-92: 🛠️ Refactor suggestion
Consider enhancing error handling and logging
While the error handling is good, there are a few improvements to consider:
- The TODO comment suggests incomplete implementation
- Using console.error might not be ideal for production environments
Consider implementing a proper error handling strategy:
- console.error( - "Sample was removed from cache before image loaded", - sampleId - ); + const error = new Error(`Sample ${sampleId} was removed from cache before image loaded`); + // Replace with your logging/error reporting service + this.handleError(error);Also, consider implementing the handleError method in the class to centralize error handling:
private handleError(error: Error) { // Integration with proper error tracking service // e.g., Sentry, Application Insights, etc. }
94-109: 🛠️ Refactor suggestion
Maintain consistent error handling approach
The error handling should follow the same pattern as suggested for the load event listener. Also, consider making the fallback strategy more explicit.
Consider this improvement:
- console.error( - "Failed to load image for sample with id", - sampleId, - "at url", - source - ); + const error = new Error(`Failed to load image for sample ${sampleId} at ${source}`); + this.handleError(error); + // Make fallback strategy more explicit + const FALLBACK_OPTIONS = { + src: BASE64_BLACK_IMAGE, + width: 2, + height: 2 + }; - image.src = BASE64_BLACK_IMAGE; + image.src = FALLBACK_OPTIONS.src;Committable suggestion was skipped due to low confidence.

107-110: 💡 Codebase verification
⚠️ Potential issueAfter analyzing the Modal component implementation and event listener management, I can now provide a final response:
Event listener cleanup needs improvement
The current implementation has a potential memory leak because:
- The "close" event listener is added in
onLookerSetbut only removed inmodalCloseHandler- There's no cleanup on component unmount
- The event listener removal is asymmetric - it's removed during modal close but not during looker changes
To fix this, add a cleanup effect:
useEffect(() => { return () => { // Cleanup on unmount activeLookerRef.current?.removeEventListener("close", modalCloseHandler); }; }, [modalCloseHandler]);And in
onLookerSet, remove any existing listener before adding a new one:const onLookerSet = useCallback((looker: fos.Lookers) => { // Remove existing listener if any activeLookerRef.current?.removeEventListener("close", modalCloseHandler); onLookerSetSubscribers.current.forEach((sub) => sub(looker)); looker.addEventListener("close", modalCloseHandler); }, []);🔗 Analysis chain
Event listener cleanup needs improvement
The current implementation has potential issues with event listener lifecycle management:
- The cleanup is asymmetric - listeners are added in
onLookerSetbut removed inmodalCloseHandler- Missing cleanup on component unmount
- No protection against multiple listener registrations
- Potential stale closure issues with
modalCloseHandlerConsider implementing this improved pattern:
const Modal = () => { + const modalCloseHandlerRef = useRef(modalCloseHandler); + + useEffect(() => { + modalCloseHandlerRef.current = modalCloseHandler; + }, [modalCloseHandler]); + + useEffect(() => { + return () => { + // Cleanup on unmount + if (activeLookerRef.current) { + activeLookerRef.current.removeEventListener( + "close", + modalCloseHandlerRef.current + ); + } + }; + }, []); + const onLookerSet = useCallback((looker: fos.Lookers) => { onLookerSetSubscribers.current.forEach((sub) => sub(looker)); + + // Remove existing listener if any + if (activeLookerRef.current) { + activeLookerRef.current.removeEventListener( + "close", + modalCloseHandlerRef.current + ); + } + looker.addEventListener("close", modalCloseHandler); }, []);Let's verify the event listener management in other components:
Let me gather more context about the Modal component implementation to better understand the event listener management.
Let me search for any cleanup effects in the Modal component to better understand the event listener management.
Let me check the full Modal component implementation to understand how the event listeners are managed.

⚠️ Potential issueAdd null check for abortController parameter
The
abortControllerparameter is used directly without null checks on line 465, which could cause runtime errors when the parameter is not provided.Add a default AbortController or add null checks:

⚠️ Potential issueAbortController Cannot Be Reused After Abort
After calling
this.abortController.abort()in thedetachmethod, theAbortControllercannot be reused. If the instance may be reattached or reused after detachment, consider reinitializing theAbortController. Since it is declared asreadonly, you might need to adjust the design to allow reinitialization.
