Working on a way to debug animations in React Native 👀 Record a gesture on device, scrub it from the browser, see where the UI or JS thread dropped frames. @keyframer_dev inspector: a babel plugin + <MotionScan /> for an on-device overlay

The talk about Keyframer - The Reanimated Visual editor it's up. 🎥 Watch it here: youtube.com/watch?v=vVVKvS3c… PS: I had only 1 day to prep for the @appjsconf talk but it was really fun :)
I'm building a visual editor for Reanimated. It's still early, but I'd love for you to try it and tell me what's missing, confusing and exciting :) 👉 keyframer.dev
