173-194: Consider additional error handling in cleanup method.The
cleanupCurrentStreammethod is now the central place for resource cleanup, but it doesn't have try/catch blocks to handle potential errors during cleanup operations. Media API operations can sometimes throw exceptions that should be caught to prevent them from interrupting the cleanup process.async cleanupCurrentStream() { + try { if (this.quaggaInitialized) { Quagga.stop() this.quaggaInitialized = false } if (this.mediaStream) { this.mediaStream.getTracks().forEach(track => track.stop()) this.mediaStream = null } if (this.webcam) { this.webcam.stop() } const webcamElement = document.getElementById("webcam") if (webcamElement && webcamElement.srcObject) { const tracks = webcamElement.srcObject.getTracks() tracks.forEach(track => track.stop()) webcamElement.srcObject = null } + } catch (error) { + console.error('Error during stream cleanup:', error) + } },

168-170: Good addition of lifecycle hook for resource cleanup!Adding the
beforeUnmountlifecycle hook ensures that media resources are properly cleaned up when the component is unmounted, preventing potential memory leaks and resource issues. This is a critical improvement for proper resource management.
190-192: Enhanced stream cleanup implementation.Stopping each track individually before setting srcObject to null is the correct approach for thoroughly releasing camera resources. Without this explicit track stopping, users might experience issues like the camera light remaining on after navigation or component destruction.
235-235: Good practice storing stream reference.Storing the media stream in a component property allows for proper cleanup later. This is a key part of the fix that enables more reliable resource management.
299-301: Improved camera cancellation flow.Simplifying the
cancelCameramethod to rely on the centralizedcleanupCurrentStreammethod reduces code duplication and ensures consistent cleanup behavior across different component lifecycle events. This is a good refactoring approach.
