## What it is
nipplejs is a dependency-free, vanilla TypeScript library that renders virtual joysticks for touch and mouse capable web interfaces. It supports static, semi, and dynamic joystick modes with multitouch, axis locking, and event-based vector output for controlling games or UIs.

## Use cases
- add an on-screen joystick to a mobile web game
- control a character with touch drag input in the browser
- build dual-stick touch controls for a web shooter
- capture analog stick vector input from touch and mouse
- create a horizontal-only slider-style touch control
- replace keyboard controls with touch controls on tablets

## When to choose
- you need a lightweight, zero-dependency virtual joystick in vanilla JS or any framework
- you want multitouch support with configurable modes, axis locking, and styling
- you're building touch-friendly games or remote-control UIs for mobile browsers

## When to avoid
- you need native mobile joystick widgets outside the browser
- you require gamepad hardware input rather than on-screen touch controls
- you need a full touch gesture library beyond joysticks
