ABOUT

This plugin allows you to detect browser's and separate element's zoom level.
It is lightweight and has no dependencies!

INSTALLATION

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

INSTALLATION NOTE:
This lib is written in ES6+ and delivering with both, transpiled and untranspiled versions:

  • main field of package.json is pointing to transpiled ES3-compatible version with CJS modules resolution;
  • module field is pointing to transpiled ES3-compatible version with ES modules resolution;
  • esnext field is pointing to the ES6+ version with ES modules resolution;

Depending on your targets you may have to use Webpack and/or Babel to pull untranspiled version of package.
See some tips on wiring thing up: https://2ality.com/2017/06/pkg-esnext.html

USAGE

import zoomLevel from "zoom-level";
 
zoomLevel(); // 1;
 
window.addEventListener("resize", () => {
  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);
 
elementZoomLevel(zoomedBlock); // 0.5;
 
window.addEventListener("resize", () => {
  elementZoomLevel(zoomedBlock); // if you zoom to 200% it'll be 1
});

TESTS

Sadly i have no idea how to manage testing of this package, due to there is no known ways to control browser's zoom level.
If you know how to do it - please let me know.
