A browser based golf swing analyzer built with Vite, React, Redux, Tailwind and Konva.js.

Video playback is completely client side - there is no video uploading or server side integration required. Swing lines are drawn using canvas with the help of Konva.js.

There are lots of swing analyzer apps available for IOS and Android, but none on the web. My goal is to try to see how close a browser implementation can get to a native app.
