devtools-detect

Detect if DevTools is open and its orientation

Useful for when you want something special to happen when DevTools is open. Like pausing canvas, adding style debug info, etc.

Demo

Install

$ npm install --save devtools-detect

Usage

<script src="node_modules/devtools-detect/index.js"></script>
<script>
	// check if it's open
	console.log('is DevTools open?', window.devtools.open);
	// check it's orientation, null if not open
	console.log('and DevTools orientation?', window.devtools.orientation);

	// get notified when it's opened/closed or orientation changes
	window.addEventListener('devtoolschange', function (e) {
		console.log('is DevTools open?', e.detail.open);
		console.log('and DevTools orientation?', e.detail.orientation);
	});
</script>

Caveats

Doesn't work if DevTools is undocked and will show false positive if you toggle any kind of sidebar.
