## What it is
Pressure.js is a lightweight JavaScript library that unifies Force Touch, 3D Touch, and Pointer Pressure handling on the web behind a single simple API. It includes a time-based polyfill for unsupported devices and supports multitouch across iPhones, MacBooks, trackpads, and pointer-event devices.

## Use cases
- handle 3D touch press events on iPhone web apps
- detect force touch pressure in the browser
- add pressure-sensitive interactions to web elements
- polyfill force press for devices without pressure support
- handle multitouch pressure on multiple elements simultaneously
- implement quick-look style deep press actions like Instagram
- support Wacom tablet and Surface pen pressure in web apps

## When to choose
- you need a unified API for Force Touch, 3D Touch, and pointer pressure across devices
- you want a tiny (~2.5kB) dependency with a polyfill fallback for unsupported hardware
- you need multitouch pressure handling on different elements at once

## When to avoid
- your project only targets modern browsers where native Pointer Events pressure suffices
- you need actively developed support for new devices (last release 2022)
- you are not building browser-based touch/pointer interactions

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, middleware
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: force-touch, 3d-touch, pointer-events, pressure-sensing, polyfill, touch-input
