Flapkit: zero-dependency React split-flap display component with sound
bennyschudel · x · 2026-09-18
Flapkit is an open-source React component simulating airport-style mechanical split-flap displays: zero dependencies, customizable fonts/colors/timing/mechanical sounds, multi-language and emoji support, with CSS and Canvas renderers. The technique builds on Jhey's 'Time Travel with JavaScript' article, using four clipped children to animate flaps without DOM duplication.
