Documentation 📖

Learn how to use the inspector and see it live in the Development tools guide.

Quick start

Include the script to load the inspector:
<script src="path/to/inspector.js"></script>

Call CKEditorInspector.attach( editor ) when the editor instance is ready:
	.create( ... )
	.then( editor => {
		CKEditorInspector.attach( editor );
	} )
	.catch( error => {
		console.error( error );
	} );

Note: You can attach to multiple editors under unique names at a time. Then you can select the editor instance in the drop–down inside the inspector panel to switch context.
CKEditorInspector.attach( {
	'header-editor': editor1,
	'footer-editor': editor2,
	// ...
} );

Call CKEditorInspector.detach( name ) to detach the inspector from an editor instance.
Tip: CKEditorInspector.attach() returns the generated name of the editor if it was not provided.
// Attach the inspector to two editor instances:
const generatedName = CKEditorInspector.attach( editor1 );
CKEditorInspector.attach( { arbitraryName: editor2 } );

// ...

// Detach from the instances:
CKEditorInspector.detach( generatedName );
CKEditorInspector.detach( 'arbitraryName' );

Attaching to all editor instances

When multiple CKEditor 5 instances are running in DOM, you can call CKEditorInspector.attachToAll( [ options ] ) to attach the inspector to all of them at the same time. A shorthand for CKEditorInspector.attach( editor, [ options ] ) called individually for each instance.
// Discover all editor instances in DOM and inspect them all.

You can also pass the optional configuration object to this method.
Note: This method works with CKEditor v12.3.0 or later. Earlier editor versions will not be discovered.

Toggling the inspector visibility

Click the button in the upper-right corner of the inspector to quickly show or hide it. You can also use the Alt+F12 (+F12 on Mac) keyboard shortcut.
The button that toggles the inspector visibility.


You can pass configuration options to CKEditorInspector.attach() and CKEditorInspector.attachToAll() methods as the last argument:
CKEditorInspector.attach( editor, {
	// configuration options
} );

CKEditorInspector.attach( { 'editor-name': editor }, {
	// configuration options
} );

CKEditorInspector.attachToAll( {
	// configuration options
} );


To attach the inspector with a collapsed UI, use the options.isCollapsed option.
Note: This option works when CKEditorInspector.attach() is called for the first time only.
CKEditorInspector.attach( { 'editor-name': editor }, {
	// Attach the inspector to the "editor" but the UI will be collapsed.
	isCollapsed: true
} );


To configure the environment:
git clone git@github.com:ckeditor/ckeditor5-inspector.git
cd ckeditor5-inspector
yarn install

Start the webpack file watcher:
yarn dev

and open http://path/to/ckeditor5-inspector/sample/inspector.html in your web browser.

When the changelog is ready, you should bump the version:
yarn release:bump-version

Note: You can use the --dry-run option to see what this task does.

Building for production

When the changelog is ready and the version was bumped, build the inspector for production:
yarn build

Note: Run the sample and make sure global CKEDITOR_INSPECTOR_VERSION is correct.
