MediaPipe Hand Tracking & Face Detection in JavaScript

A beginner MediaPipe JavaScript example builds a rainbow drawing app in the browser with real-time hand tracking and face detection. To run the app, serve the HTML file over HTTP and use the provided code to request the webcam feed. This requires no npm or backend setup, making it a zero-installation project. To start, create an index.html file and paste in the provided HTML code, then replace the console.log line with the code to request the webcam feed.
