CKEditor 5 inspector

The official CKEditor 5 rich text editor instance inspector for developers.

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:

ClassicEditor
	.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.
CKEditorInspector.attachToAll();

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.

Configuration

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
} );

isCollapsed

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
} );

git clone [e-mail]:ckeditor/ckeditor5-inspector.git

Updating the version

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.

Publishing the npm package

Finally, make the changes public:
