Package Exports

window-resizeto

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 (window-resizeto) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

window-resizeto

A window.resizeTo polyfill for test environments like Jest & JSDOM.

Installation

npm i -D window-resizeto

Usage

There are a few different ways you can use window-resizeto:

With Jest:

// jest.config.js
module.exports = {
  setupFilesAfterEnv: [
    // polyfill window.resizeTo
    'window-resizeto/polyfill'
  ]
}

// some-test.spec.js
window.resizeTo(500, 500)
// window is now resize to 500x500

Standalone with the polyfill:

import 'window-resizeto/polyfill'

window.resizeTo(500, 500)
// window is now resized to 500x500

With the ponyfill:

import { resizeTo } from 'window-resizeto'

resizeTo(window, 500, 500)
// window is now resized to 500x500

How it works

Basically just sets the window's outerWidth, outerHeight, innerWidth, innerHeight, and fires a resize event. The source code is currently just <10 LoC, so take a look under the hood! :)

Credits

Inspiration for creating this came from mq-polyfill and a few other code samples that are nearly exact replicas. I wanted a package I could re-use in my projects' tests instead of having to constantly create a helper file, and so window-resizeto was born!
