Get Started

Zoom Image is a small collection of utilities for zooming image on the web. It is written in pure TypeScript and has no dependencies. The library is built with framework agnostic in mind, so it can be used with any framework adapters or even without

Installation

pnpm

$ pnpm add @zoom-image/core

npm

$ npm install @zoom-image/core

yarn

$ yarn add @zoom-image/core

CDN

<script src="https://unpkg.com/@zoom-image/core"></script>

Everything will be exposed to global as window.ZoomImage

Example with Vanilla JS

Simply importing the utilities you need from @zoom-image/core

<div id="container" class="imageContainer"><img class="image" alt="Large Pic" src="/image.webp" /></div>

.imageContainer {
  width: var(--imageContainerWidth);
  height: var(--imageContainerHeight);
}

.image {
  max-width: 100%;
  max-height: 100%;
}

import { createZoomImageWheel } from "@zoom-image/core"

const container = document.getElementById("container")
createZoomImageWheel(container)
