Package Exports

zoom-level

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (zoom-level) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

ABOUT

This plugin allows you to detect browser's and separate element's zoom level.

INSTALLATION

npm install zoom-level
# or via yarn
yarn add zoom-level

USAGE

import zoomLevel from "zoom-level";

console.log(zoomLevel()); // 1;

window.addEventListener("resize", () => {
  console.log(zoomLevel()); // will return current browser's zoom level
});

Or, in case you want to detect separate element's zoom level (they can use own zoom CSS property which stacks with browser's one);

import { elementZoomLevel } from "zoom-level";

const zoomedBlock = document.createElement("div");
zoomedBlock.style.zoom = 0.5;
zoomedBlock.style.width = "150px";
zoomedBlock.style.height = "150px";
zoomedBlock.style.margin = "32px";
zoomedBlock.style.padding = "32px";
zoomedBlock.style.background = "rgba(0,0,0,.05)";
zoomedBlock.innerText = "Lorem ipusm dolor sit amet";
document.appendChild(zoomedBlock);

console.log(elementZoomLevel(zoomedBlock)); // 0.5;

window.addEventListener("resize", () => {
  console.log(elementZoomLevel(zoomedBlock)); // if you zoom to 200% it'll be 1
});
