The parse function now checks for empty input at the top and returns immediately, avoiding unnecessary processing overhead for trivial cases. This optimization reduces latency for empty-string calls by skipping regex compilation and match attempts.
Implement avatar management with image upload, client-side cropping, and server-side storage. Users can now upload profile pictures from their local filesystem, crop them to a square aspect ratio using a drag-and-resize interface, and save the result. The backend stores cropped images in a dedicated avatars directory and updates the user record with the new avatar path. Includes validation for file type and size limits, plus fallback to default avatar on error.
