DecoupledEditor (editor-decoupled)
@ckeditor/ckeditor5-editor-decoupled/src/decouplededitor
The decoupled editor implementation. It provides an inline editable and a toolbar. However, unlike other editors, it does not render these components anywhere in the DOM unless configured.
This type of an editor is dedicated to integrations which require a customized UI with an open structure, allowing developers to specify the exact location of the interface.
See the document editor demo to learn about possible use cases for the decoupled editor.
In order to create a decoupled editor instance, use the static
DecoupledEditor.create()
method.
Note that you will need to attach the editor toolbar and menu bar to your web page manually, in a desired place, after the editor is initialized.

readonly inherited
editing : EditingController
module:editor-decoupled/decouplededitor~DecoupledEditor#editing
The editing controller. Controls user input and rendering the content for editing.
-
Defines whether the editor is in the read-only mode.
In read-only mode the editor commands are disabled so it is not possible to modify the document by using them. Also, the editable element(s) become non-editable.
In order to make the editor read-only, you need to call the
enableReadOnlyMode
method:editor.enableReadOnlyMode( 'feature-id' );
- Later, to turn off the read-only mode, call
disableReadOnlyMode
:
editor.disableReadOnlyMode( 'feature-id' );
Parameters
value : boolean
- Later, to turn off the read-only mode, call

keystrokes : EditingKeystrokeHandler
module:editor-decoupled/decouplededitor~DecoupledEditor#keystrokes
An instance of the
EditingKeystrokeHandler
.It allows setting simple keystrokes:
// Execute the bold command on Ctrl+E: editor.keystrokes.set( 'Ctrl+E', 'bold' ); // Execute your own callback: editor.keystrokes.set( 'Ctrl+E', ( data, cancel ) => { console.log( data.keyCode ); // Prevent the default (native) action and stop the underlying keydown event // so no other editor feature will interfere. cancel(); } );
Note: Certain typing-oriented keystrokes (like Backspace or Enter) are handled by a low-level mechanism and trying to listen to them via the keystroke handler will not work reliably. To handle these specific keystrokes, see the events fired by the editing view document (

bind( bindProperties ) → MultiBindChain
module:editor-decoupled/decouplededitor~DecoupledEditor#bind:MANY_BIND
Binds observable properties to other objects implementing the
Observable
interface.Read more in the dedicated guide covering the topic of property bindings with some additional examples.
Consider two objects: a
button
and an associatedcommand
(bothObservable
).A simple property binding could be as follows:
button.bind( 'isEnabled' ).to( command, 'isEnabled' );
or even shorter:
button.bind( 'isEnabled' ).to( command );
which works in the following way:
button.isEnabled
instantly equalscommand.isEnabled
,- whenever
command.isEnabled
changes,button.isEnabled
will immediately reflect its value.
Note: To release the binding, use
unbind
.You can also "rename" the property in the binding by specifying the new name in the
to()
chain:button.bind( 'isEnabled' ).to( command, 'isWorking' );
It is possible to bind more than one property at a time to shorten the code:
button.bind( 'isEnabled', 'value' ).to( command );
which corresponds to:
button.bind( 'isEnabled' ).to( command ); button.bind( 'value' ).to( command );
The binding can include more than one observable, combining multiple data sources in a custom callback:
button.bind( 'isEnabled' ).to( command, 'isEnabled', ui, 'isVisible', ( isCommandEnabled, isUIVisible ) => isCommandEnabled && isUIVisible );
Using a custom callback allows processing the value before passing it to the target property:
button.bind( 'isEnabled' ).to( command, 'value', value => value === 'heading1' );
It is also possible to bind to the same property in an array of observables. To bind a
button
to multiple commands (alsoObservables
) so that each and every one of them must be enabled for the button to become enabled, use the following code:button.bind( 'isEnabled' ).toMany( [ commandA, commandB, commandC ], 'isEnabled', ( isAEnabled, isBEnabled, isCEnabled ) => isAEnabled && isBEnabled && isCEnabled );
Parameters
bindProperties : Array<'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'data' | 'focus' | 'id' | 'config' | 'destroy' | 'isReadOnly' | 'ui' | 'editing' | 'model' | 'locale' | 't' | 'execute' | 'plugins' | 'keystrokes' | 'accessibility' | 'commands' | 'conversion' | 'state' | 'enableReadOnlyMode' | 'disableReadOnlyMode' | 'setData' | 'getData' | 'initPlugins' | 'sourceElement' | 'updateSourceElement'>

decorate( methodName ) → void
module:editor-decoupled/decouplededitor~DecoupledEditor#decorate
Turns the given methods of this object into event-based ones. This means that the new method will fire an event (named after the method) and the original action will be plugged as a listener to that event.
Read more in the dedicated guide covering the topic of decorating methods with some additional examples.
Decorating the method does not change its behavior (it only adds an event), but it allows to modify it later on by listening to the method's event.
For example, to cancel the method execution the event can be stopped:
class Foo extends ObservableMixin() { constructor() { super(); this.decorate( 'method' ); } method() { console.log( 'called!' ); } } const foo = new Foo(); foo.on( 'method', ( evt ) => { evt.stop(); }, { priority: 'high' } ); foo.method(); // Nothing is logged.
Note: The high priority listener has been used to execute this particular callback before the one which calls the original method (which uses the "normal" priority).
It is also possible to change the returned value:
foo.on( 'method', ( evt ) => { evt.return = 'Foo!'; } ); foo.method(); // -> 'Foo'
Finally, it is possible to access and modify the arguments the method is called with:
method( a, b ) { console.log( `${ a }, ${ b }` ); } // ... foo.on( 'method', ( evt, args ) => { args[ 0 ] = 3; console.log( args[ 1 ] ); // -> 2 }, { priority: 'high' } ); foo.method( 1, 2 ); // -> '3, 2'
Parameters
methodName : 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'data' | 'focus' | 'id' | 'config' | 'destroy' | 'isReadOnly' | 'ui' | 'editing' | 'model' | 'locale' | 't' | 'execute' | 'plugins' | 'keystrokes' | 'accessibility' | 'commands' | 'conversion' | 'state' | 'enableReadOnlyMode' | 'disableReadOnlyMode' | 'setData' | 'getData' | 'initPlugins' | 'sourceElement' | 'updateSourceElement'

Delegates selected events to another
Emitter
. For instance:emitterA.delegate( 'eventX' ).to( emitterB ); emitterA.delegate( 'eventX', 'eventY' ).to( emitterC );
then
eventX
is delegated (fired by)emitterB
andemitterC
along withdata
:emitterA.fire( 'eventX', data );
and
eventY
is delegated (fired by)emitterC
along withdata
:emitterA.fire( 'eventY', data );

destroy() → Promise<unknown>
module:editor-decoupled/decouplededitor~DecoupledEditor#destroy
Destroys the editor instance, releasing all resources used by it.
Updates the original editor element with the data if the
updateSourceElementOnDestroy
configuration option is set totrue
.Note: The decoupled editor does not remove the toolbar and editable when destroyed. You can do that yourself in the destruction chain:
editor.destroy() .then( () => { // Remove the toolbar from DOM. editor.ui.view.toolbar.element.remove(); // Remove the editable from DOM. editor.ui.view.editable.element.remove(); console.log( 'Editor was destroyed' ); } );
Returns

disableReadOnlyMode( lockId ) → void
module:editor-decoupled/decouplededitor~DecoupledEditor#disableReadOnlyMode
Removes the read-only lock from the editor with given lock ID.
When no lock is present on the editor anymore, then the
isReadOnly
property will be set tofalse
.Parameters
lockId : string | symbol
The lock ID for setting the editor to the read-only state.
Returns
void
-
inherited
enableReadOnlyMode( lockId ) → void
module:editor-decoupled/decouplededitor~DecoupledEditor#enableReadOnlyMode
Turns on the read-only mode in the editor.
Editor can be switched to or out of the read-only mode by many features, under various circumstances. The editor supports locking mechanism for the read-only mode. It enables easy control over the read-only mode when many features wants to turn it on or off at the same time, without conflicting with each other. It guarantees that you will not make the editor editable accidentally (which could lead to errors).
Each read-only mode request is identified by a unique id (also called "lock"). If multiple plugins requested to turn on the read-only mode, then, the editor will become editable only after all these plugins turn the read-only mode off (using the same ids).
Note, that you cannot force the editor to disable the read-only mode if other plugins set it.
After the first
enableReadOnlyMode()
call, theisReadOnly
property will be set totrue
:editor.isReadOnly; // `false`. editor.enableReadOnlyMode( 'my-feature-id' ); editor.isReadOnly; // `true`.
You can turn off the read-only mode ("clear the lock") using the
disableReadOnlyMode()
method:editor.enableReadOnlyMode( 'my-feature-id' ); // ... editor.disableReadOnlyMode( 'my-feature-id' ); editor.isReadOnly; // `false`.
All "locks" need to be removed to enable editing:
editor.enableReadOnlyMode( 'my-feature-id' ); editor.enableReadOnlyMode( 'my-other-feature-id' ); // ... editor.disableReadOnlyMode( 'my-feature-id' ); editor.isReadOnly; // `true`. editor.disableReadOnlyMode( 'my-other-feature-id' ); editor.isReadOnly; // `false`.
Parameters
lockId : string | symbol
A unique ID for setting the editor to the read-only state.

fire( eventOrInfo, args ) → GetEventInfo<TEvent>[ 'return' ]
module:editor-decoupled/decouplededitor~DecoupledEditor#fire
Fires an event, executing all callbacks registered for it.
The first parameter passed to callbacks is an
EventInfo
object, followed by the optionalargs
provided in thefire()
method call.Type parameters
Parameters
eventOrInfo : GetNameOrEventInfo<TEvent>
The name of the event or
EventInfo
object if event is delegated.args : TEvent[ 'args' ]
Additional arguments to be passed to the callbacks.
Returns
GetEventInfo<TEvent>[ 'return' ]

. However, the return value can be changed by listeners through modification of theevt.return
's property (the event info is the first param of every callback).
-
Focuses the editor.

getData( [ options ] = { [options.rootName], [options.trim], options[key: string] } ) → string
module:editor-decoupled/decouplededitor~DecoupledEditor#getData
Gets the data from the editor.
editor.getData(); // -> '<p>This is editor!</p>'
If your editor implementation uses multiple roots, you should pass root name as one of the options:
editor.getData( { rootName: 'header' } ); // -> '<p>Content for header part.</p>'
By default, the editor outputs HTML. This can be controlled by injecting a different data processor. See the Markdown output guide for more details.
A warning is logged when you try to retrieve data for a detached root, as most probably this is a mistake. A detached root should be treated like it is removed, and you should not save its data. Note, that the detached root data is always an empty string.
Parameters
[ options ] : object
Additional configuration for the retrieved data. Editor features may introduce more configuration options that can be set through this parameter.
Properties[ options.rootName ] : string
Root name. Defaults to
'main'
.[ options.trim ] : 'none' | 'empty'
Whether returned data should be trimmed. This option is set to
'empty'
by default, which means that whenever editor content is considered empty, an empty string is returned. To turn off trimming use'none'
. In such cases exact content will be returned (for example'<p> </p>'
for an empty editor).options[key: string] : unknown
Returns
string
Output data.

listenTo( emitter, event, callback, [ options ] ) → void
module:editor-decoupled/decouplededitor~DecoupledEditor#listenTo:BASE_EMITTER
Registers a callback function to be executed when an event is fired in a specific (emitter) object.
Events can be grouped in namespaces using
:
. When namespaced event is fired, it additionally fires all callbacks for that namespace.// myEmitter.on( ... ) is a shorthand for myEmitter.listenTo( myEmitter, ... ). myEmitter.on( 'myGroup', genericCallback ); myEmitter.on( 'myGroup:myEvent', specificCallback ); // genericCallback is fired. myEmitter.fire( 'myGroup' ); // both genericCallback and specificCallback are fired. myEmitter.fire( 'myGroup:myEvent' ); // genericCallback is fired even though there are no callbacks for "foo". myEmitter.fire( 'myGroup:foo' );
An event callback can stop the event and set the return value of the
fire
method.Type parameters

Creates and sets the value of an observable properties of this object. Such a property becomes a part of the state and is observable.
It accepts a single object literal containing key/value pairs with properties to be set.
This method throws the
observable-set-cannot-override
error if the observable instance already has a property with the given property name. This prevents from mistakenly overriding existing properties and methods, but means thatfoo.set( 'bar', 1 )
may be slightly slower thanfoo.bar = 1
.In TypeScript, those properties should be declared in class using
declare
keyword. In example:public declare myProp1: number; public declare myProp2: string; constructor() { this.set( { 'myProp1: 2, 'myProp2: 'foo' } ); }
Parameters
values : object
An object with
name=>value
pairs.

create( sourceElementOrData, config ) → Promise<DecoupledEditor>
module:editor-decoupled/decouplededitor~DecoupledEditor.create
Creates a new decoupled editor instance.
Note: remember that
DecoupledEditor
does not append the toolbar element to your web page, so you have to do it manually after the editor has been initialized.There are two ways how the editor can be initialized.
Using an existing DOM element (and loading data from it)
You can initialize the editor using an existing DOM element:
DecoupledEditor .create( document.querySelector( '#editor' ) ) .then( editor => { console.log( 'Editor was initialized', editor ); // Append the toolbar to the <body> element. document.body.appendChild( editor.ui.view.toolbar.element ); } ) .catch( err => { console.error( err.stack ); } );
The element's content will be used as the editor data and the element will become the editable element.
Creating a detached editor
Alternatively, you can initialize the editor by passing the initial data directly as a string. In this case, you will have to manually append both the toolbar element and the editable element to your web page.
DecoupledEditor .create( '<p>Hello world!</p>' ) .then( editor => { console.log( 'Editor was initialized', editor ); // Append the toolbar to the <body> element. document.body.appendChild( editor.ui.view.toolbar.element ); // Initial data was provided so the editor UI element needs to be added manually to the DOM. document.body.appendChild( editor.ui.getEditableElement() ); } ) .catch( err => { console.error( err.stack ); } );
This lets you dynamically append the editor to your web page whenever it is convenient for you. You may use this method if your web page content is generated on the client side and the DOM structure is not ready at the moment when you initialize the editor.
Using an existing DOM element (and data provided in
config.initialData
)You can also mix these two ways by providing a DOM element to be used and passing the initial data through the configuration:
DecoupledEditor .create( document.querySelector( '#editor' ), { initialData: '<h2>Initial data</h2><p>Foo bar.</p>' } ) .then( editor => { console.log( 'Editor was initialized', editor ); // Append the toolbar to the <body> element. document.body.appendChild( editor.ui.view.toolbar.element ); } ) .catch( err => { console.error( err.stack ); } );
This method can be used to initialize the editor on an existing element with the specified content in case if your integration makes it difficult to set the content of the source element.
Note that an error will be thrown if you pass the initial data both as the first parameter and also in the configuration.
Configuring the editor
See the editor configuration documentation to learn more about customizing plugins, toolbar and more.
Parameters
sourceElementOrData : string | HTMLElement
The DOM element that will be the source for the created editor or the editor's initial data.
If a DOM element is passed, its content will be automatically loaded to the editor upon initialization. The editor data will be set back to the original element once the editor is destroyed only if the updateSourceElementOnDestroy option is set to
true
.If the initial data is passed, a detached editor will be created. In this case you need to insert it into the DOM manually. It is available via
editor.ui.getEditableElement()
.config : EditorConfig
The editor configuration.
Defaults to
{}
Returns
Promise<DecoupledEditor>
A promise resolved once the editor is ready. The promise resolves with the created editor instance.
Events
-
inherited
change:isReadOnly( eventInfo, name, value, oldValue )
module:editor-decoupled/decouplededitor~DecoupledEditor#event:change:isReadOnly
Fired when the
isReadOnly
property changed value.Parameters
eventInfo : EventInfo
An object containing information about the fired event.
name : string
Name of the changed property (
isReadOnly
).value : boolean
New value of the
isReadOnly
property with given key ornull
, if operation should remove property.oldValue : boolean
Old value of the
isReadOnly
property with given key ornull
, if property was not set before.
-

change:state( eventInfo, name, value, oldValue )
module:editor-decoupled/decouplededitor~DecoupledEditor#event:change:state
Fired when the
state
property changed value.Parameters
eventInfo : EventInfo
An object containing information about the fired event.
name : string
Name of the changed property (
state
).value : 'ready' | 'initializing' | 'destroyed'
New value of the
state
property with given key ornull
, if operation should remove property.oldValue : 'ready' | 'initializing' | 'destroyed'
Old value of the

property with given key ornull
, if property was not set before.
-
inherited
change:{property}( eventInfo, name, value, oldValue )
module:editor-decoupled/decouplededitor~DecoupledEditor#event:change:{property}
Fired when a property changed value.
observable.set( 'prop', 1 ); observable.on<ObservableChangeEvent<number>>( 'change:prop', ( evt, propertyName, newValue, oldValue ) => { console.log( `${ propertyName } has changed from ${ oldValue } to ${ newValue }` ); } ); observable.prop = 2; // -> 'prop has changed from 1 to 2'
Parameters
eventInfo : EventInfo
An object containing information about the fired event.
name : string
The property name.
value : TValue
The new property value.
oldValue : TValue
The previous property value.
-
Fired when this editor instance is destroyed. The editor at this point is not usable and this event should be used to perform the clean-up in any plugin.
See also the
editor.state
property.Parameters
eventInfo : EventInfo
An object containing information about the fired event.
-
Fired when the data and all additional editor components are ready.
Note: This event is most useful for plugin developers. When integrating the editor with your website or application, you do not have to listen to
editor#ready
because when the promise returned by the staticEditor.create()
event is resolved, the editor is already ready. In fact, since the first moment when the editor instance is available to you is insidethen()
's callback, you cannot even add a listener to theeditor#ready
event.See also the
editor.state
property.Parameters
eventInfo : EventInfo
An object containing information about the fired event.
-
inherited
set:isReadOnly( eventInfo, name, value, oldValue )
