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.
This package has a lot of flaws. It used to work better, but browsers changed, and the detection now has too many false-positives.
npm install devtools-detect<script type="module">
import devtools from './node_modules/devtools-detect/index.js';
// Check if it's open
console.log('Is DevTools open:', devtools.isOpen);
// Check it's orientation, `undefined` if not open
console.log('DevTools orientation:', devtools.orientation);
// Get notified when it's opened/closed or orientation changes
window.addEventListener('devtoolschange', event => {
console.log('Is DevTools open:', event.detail.isOpen);
console.log('DevTools orientation:', event.detail.orientation);
});
</script>- Chrome DevTools
- Safari DevTools
- Firefox DevTools
- Opera DevTools
Doesn't work if DevTools is undocked and will show false positive if you toggle any kind of sidebar.
