## What it is
Hammer.js is a small JavaScript library for detecting and handling multi-touch gestures like tap, swipe, pinch, and press in web applications. It ships with built-in recognizers and lets developers define custom gestures via a manager and recognizer API.

## Use cases
- add swipe navigation to a mobile web app
- detect pinch-to-zoom on an image gallery
- handle tap and double-tap events on touch devices
- implement press-and-hold interactions
- create custom multi-touch gestures like triple tap
- make a webapp feel native on tablets and phones

## When to choose
- you need touch gesture recognition in a browser-based app
- you want a tiny, dependency-free gesture library
- you need custom gesture recognizers beyond the built-ins

## When to avoid
- your app is desktop-only with mouse input
- you need full pointer event handling rather than gestures
- you're using a framework that already provides gesture abstractions

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, animation
- domain: web-development, frontend
- platform: browser
- tags: touch-gestures, mobile-web, gesture-recognition, dom-events, javascript
