Window Opener

A small javaScript utility to make sure that window.open actually opens same domain windows at the size you requested.

Why

Opening a window with a set viewport is notoriously difficult across all the different browsers, and they usually end up 20px or so too short.

How

It opens a new window as per usual, but then checks the innerHeight and innerWidth match the initial request, and adjusts the window size accordingly.

Wont

Unfortunately it will not run cross domain due to same origin security policies.

Installation

NPM

npm install window-opener --save

YARN

yarn add window-opener

bower install window-opener --save

Manual

    windowOpener.open('http://www.domain.com', '_blank', 'width=500px, height=500px');
</script>

Demo

A super simple demo

API

open( url, windowName, [windowFeatures] )

This is exactly the same as window.open

wrap()

Wraps the native window.open method with windowOpener.open, meaning you don't have to update any of your code.

windowOpener.wrap();

...

// all window.open calls now run via windowOpener.open
window.open('http://www.domain.com', '_blank', 'width=500px, height=500px');

unWrap()

Restores the native window.open method
