Hammer.js Multi-touch Gestures

Hammer.js is a JavaScript library designed for detecting and handling multi-touch gestures such as tap, doubletap, press, pan, swipe, pinch, and rotate in web applications. It aims to provide a unified API across touch, mouse, and pointer events, offering a lightweight solution with no external dependencies and a small footprint (7.34 kB minified + gzipped for v2.0.8). However, the main `hammerjs` package has not seen active development since its last stable release, version 2.0.8, published over 10 years ago on April 22, 2016. While it was a popular choice for gesture recognition, its maintenance status means that users often look to forks like `@egjs/hammerjs` for continued support or migrate to newer, actively maintained gesture libraries.
