Lazarus Strikes npm Again with New Wave of Malicious Packages
The Socket Research Team has discovered six new malicious npm packages linked to North Korea’s Lazarus Group, designed to steal credentials and deploy backdoors.
wheel-gestures
Advanced tools
wheel gestures and momentum detection in the browser
Install wheel-gestures using your package manager:
yarn add wheel-gestures # OR npm install wheel-gestures
Import and create an instance of WheelGestures and then add the element you want to observe.
import { WheelGestures } from 'wheel-gestures'
// create an instance per element
const wheelGestures = WheelGestures()
// find and observe the element the user can interact with
const element = window.document.querySelector('.slider')
wheelGestures.observe(element)
// add your event callback
wheelGestures.on('wheel', (wheelEventState) => {
//...
})
There are options to customize the behaviour.
This is the TypeScript type of the WheelEventState object provided. Even if you do not use TypeScript, this might be helpful to see how the data is provided:
export type VectorXYZ = [number, number, number]
export interface WheelEventState {
isStart: boolean
isMomentum: boolean
isEnding: boolean
isMomentumCancel: boolean
axisDelta: VectorXYZ
axisVelocity: VectorXYZ
axisMovement: VectorXYZ
axisMovementProjection: VectorXYZ
event: WheelEvent | WheelEventData
previous?: WheelEventState
}

OS & Browsers
Other people also thought that it might be helpful for some interactions to be able to distinguish between user initiated wheel events and the ones that are triggered by inertia scroll, but none of the other known libraries delivered results in the precision I needed, so I developed my own solution.
