A node module to detect if the local computer has a fullscreen window open

detect-fullscreen - Detect fullscreen windows in node.js

This is some code that tries to detect if the user has a fullscreen window open. It should work pretty well in OSX. It works in Windows but needs some better support for computers with multiple screens. Unfortunately it won't work at all in Linux right now, although I would like to change that.

How To Use It

var x = require('detect-fullscreen')
console.log(x.isFullscreen())
=> true/false

How It Works

It works a little differently in OSX and Windows. You can see the code at Fullscreen.css

On OSX, the code iterates through all of the elements visible on the screen. One of these elements might be the Menubar which appears at the top of the screen. If that element doesn't exist, we assume that there's a fullscreen window on that display.

On Windows, the code checks the bounds of the active window. If they meet/exceed the resolution of the screen, we treat it as a fullscreen window.

What Happens With Multiple Displays?

If a computer has multiple displays, and one of them has a fullscreen window, then isFullscreen() will return true.

How to recompile for a different node.js version?

I am trying to use this package with electron and I get this error when I include it in the project.

Error: The module '/Users/vik/Documents/code/app/node_modules/detect-fullscreen/build/Release/Fullscreen.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 93. This version of Node.js requires
NODE_MODULE_VERSION 110. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

I tried using npm install and npm rebuild but it doesn't fix the problem. Any help here would be appreciated. Thanks!

Fullscreen detection is broken for newer macs which have a notch

It seems like notch is somehow causing the fullscreen detection to not work. Run the example in the readme to recreate the bug.
