Angular rich text editor component

Angular is a TypeScript-based, open-source, single-page web application framework. The CKEditor 5 component for Angular supports integrating different editor types.

Starting from version 6.0.0 of this package, you can use native type definitions provided by CKEditor 5. Check the details about {@link getting-started/setup/typescript-support TypeScript support}.

Supported Angular versions

Because of the breaking changes in the Angular library output format, the @ckeditor/ckeditor5-angular package is released in the following versions to support various Angular ecosystems:

CKEditor 5 version	Angular version	Details
Actively supported versions
`^6`	`13+`	Requires CKEditor 5 in version 37 or higher.
Past releases (no longer maintained)
`^5`	`13+`	Requires Angular in version 13+ or higher. Lower versions are no longer maintained.
`^5`	`13+`	Requires Angular in version 13+ or higher. Lower versions are no longer maintained.
`^4`	`9.1+`	Requires CKEditor 5 in version 34 or higher.
`^3`	`9.1+`	Requires Node.js in version 14 or higher.
`^2`	`9.1+`	Migration to TypeScript 4. Declaration files are not backward compatible.
`^1`	`5.x - 8.x`	Angular versions are no longer maintained.

All available Angular versions are listed on npm, where they can be pulled from.

Quick start

Using CKEditor 5 Builder

The easiest way to use CKEditor 5 in your Angular application is by configuring it with CKEditor 5 Builder and integrating it with your application. Builder offers an easy-to-use user interface to help you configure, preview, and download the editor suited to your needs. You can easily select:

the features you need,
the preferred framework (React, Angular, Vue or Vanilla JS),
the preferred distribution method.

You get ready-to-use code tailored to your needs!

Setting up the project

This guide assumes you already have a Angular project. To create such a project, you can use Angular CLI. Refer to the Angular documentation to learn more.

Installing from npm

First, install the CKEditor 5 packages:

ckeditor5 – package with open-source plugins and features.
ckeditor5-premium-features – package with premium plugins and features.

Depending on your configuration and chosen plugins, you may need to install the first or both packages.

npm install ckeditor5 ckeditor5-premium-features

Then, install the CKEditor 5 WYSIWYG editor component for Angular:

npm install @ckeditor/ckeditor5-angular

The following setup differs depending on the type of component you use.

NGModule components

If you want to use NGModule components, add the CKEditorModule to the imports array. It will make the CKEditor 5 component available in your Angular application.

// app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { CKEditorModule } from '@ckeditor/ckeditor5-angular';

import { AppComponent } from './app.component';

@NgModule( {
	declarations: [
		AppComponent
	],
	imports: [
		BrowserModule,
		CKEditorModule
	],
	providers: [],
	bootstrap: [ AppComponent ]
} )
export class AppModule { }

Then, import the editor in your Angular component and assign it to a public property to make it accessible from the template. The below example shows how to use the component with open-source and premium plugins.

// app.component.ts

import { Component } from '@angular/core';
import { ClassicEditor, Bold, Essentials, Italic, Mention, Paragraph, Undo } from 'ckeditor5';
import { SlashCommand } from 'ckeditor5-premium-features';

import 'ckeditor5/ckeditor5.css';
import 'ckeditor5-premium-features/ckeditor5-premium-features.css';

@Component( {
	selector: 'app-root',
	templateUrl: './app.component.html',
	styleUrls: [ './app.component.css' ]
} )
export class AppComponent {
	title = 'angular';

	public Editor = ClassicEditor;
	public config = {
		toolbar: [ 'undo', 'redo', '|', 'bold', 'italic' ],
		plugins: [
			Bold, Essentials, Italic, Mention, Paragraph, SlashCommand, Undo
		],
		licenseKey: '<YOUR_LICENSE_KEY>',
		mention: {
			// Mention configuration
		}
	}
}

Finally, use the <ckeditor> tag in the template to run the rich text editor:

<!-- app.component.html -->

<ckeditor [editor]="Editor" [config]="config" data="<p>Hello, world!</p>"></ckeditor>

Standalone components

Standalone components provide a simplified way to build Angular applications. They are enabled in Angular 17 by default. Standalone components aim to simplify the setup and reduce the need for NGModules. That is why you do not need such a module in this case.

Instead, add the CKEditorModule to the imports in your app component. The component needs the standalone option set to true.

import { Component } from '@angular/core';
import { CKEditorModule } from '@ckeditor/ckeditor5-angular';
import { ClassicEditor, Bold, Essentials, Italic, Mention, Paragraph, Undo } from 'ckeditor5';
import { SlashCommand } from 'ckeditor5-premium-features';

import 'ckeditor5/ckeditor5.css';
import 'ckeditor5-premium-features/ckeditor5-premium-features.css';

@Component( {
	selector: 'app-root',
	templateUrl: './app.component.html',
	imports: [ CKEditorModule ],
	standalone: true
} )
export class AppComponent {
	title = 'angular';

	public Editor = ClassicEditor;
	public config = {
		toolbar: [ 'undo', 'redo', '|', 'bold', 'italic' ],
		plugins: [
			Bold, Essentials, Italic, Mention, Paragraph, SlashCommand, Undo
		],
		licenseKey: '<YOUR_LICENSE_KEY>',
		mention: {
			// Mention configuration
		}
	}
}

Then, use the <ckeditor> tag in the template to run the rich text editor:

<!-- app.component.html -->

<ckeditor [editor]="Editor" [config]="config" data="<p>Hello, world!</p>"></ckeditor>

Supported `@Input` properties

The following @Input properties are supported by the CKEditor 5 rich text editor component for Angular:

`editor` (required)

The {@link getting-started/setup/editor-lifecycle Editor} which provides the static {@link module:core/editor/editor~Editor.create create()} method to create an instance of the editor:

<ckeditor [editor]="Editor"></ckeditor>

`config`

The {@link module:core/editor/editorconfig~EditorConfig configuration} of the editor:

<ckeditor [config]="{ toolbar: [ 'heading', '|', 'bold', 'italic' ] }"></ckeditor>

`data`

The initial data of the editor. It can be a static value:

<ckeditor data="<p>Hello, world!</p>"></ckeditor>

or a shared parent component's property

@Component( {
	// ...
} )
export class MyComponent {
	public editorData = '<p>Hello, world!</p>';
	// ...
}

<ckeditor [data]="editorData"></ckeditor>

`tagName`

The tag name of the HTML element on which the rich text editor will be created.

The default tag is <div>.

<ckeditor tagName="textarea"></ckeditor>

`disabled`

Controls the editor's {@link module:core/editor/editor~Editor#isReadOnly read–only} state:

@Component( {
	// ...
} )
export class MyComponent {
	public isDisabled = false;
	// ...
	toggleDisabled() {
		this.isDisabled = !this.isDisabled
	}
}

<ckeditor [disabled]="isDisabled"></ckeditor>

<button (click)="toggleDisabled()">
	{{ isDisabled ? 'Enable editor' : 'Disable editor' }}
</button>

`watchdog`

An instance of the {@link module:watchdog/contextwatchdog~ContextWatchdog ContextWatchdog} class that is responsible for providing the same context to multiple editor instances and restarting the whole structure in case of crashes.

import CKSource from 'path/to/custom/build';

const Context = CKSource.Context;
const Editor = CKSource.Editor;
const ContextWatchdog = CKSource.ContextWatchdog;

@Component( {
	// ...
} )
export class MyComponent {
	public editor = Editor;
	public watchdog: any;
	public ready = false;

	ngOnInit() {
		const contextConfig = {};

		this.watchdog = new ContextWatchdog( Context );

		this.watchdog.create( contextConfig )
			.then( () => {
				this.ready = true;
			} );
	}
}

<div *ngIf="ready">
	<ckeditor [watchdog]="watchdog"></ckeditor>
	<ckeditor [watchdog]="watchdog"></ckeditor>
	<ckeditor [watchdog]="watchdog"></ckeditor>
</div>

`editorWatchdogConfig`

If the watchdog property is not used, {@link module:watchdog/editorwatchdog~~EditorWatchdog EditorWatchdog} will be used by default. editorWatchdogConfig property allows for passing a {@link module:watchdog/watchdog~~WatchdogConfig config} to that watchdog.

@Component( {
	// ...
} )
export class MyComponent {
	public myWatchdogConfig = {
		crashNumberLimit: 5,
		// ...
	};
	// ...
}

<ckeditor [editorWatchdogConfig]="myWatchdogConfig"></ckeditor>

`disableTwoWayDataBinding`

Allows disabling the two-way data binding mechanism. The default value is false.

The reason for the introduction of this option are performance issues in large documents. By default, while using the ngModel directive, whenever the editor's data is changed, the component must synchronize the data between the editor instance and the connected property. This results in calling the {@link module:core/editor/editor~Editor#getData editor.getData()} function, which causes a massive slowdown while typing in large documents.

This option allows the integrator to disable the default behavior and only call the {@link module:core/editor/editor~Editor#getData editor.getData()} method on demand, which prevents the slowdowns. You can read more in the relevant issue.

Supported `@Output` properties

The following @Output properties are supported by the CKEditor 5 rich text editor component for Angular:

`ready`

Fired when the editor is ready. It corresponds with the editor#ready event. It is fired with the editor instance.

Note that this method might be called multiple times. Apart from initialization, it is also called whenever the editor is restarted after a crash. Do not keep the reference to the editor instance internally, because it will change in case of restart. Instead, you should use watchdog.editor property.

`change`

Fired when the content of the editor has changed. It corresponds with the {@link module:engine/model/document~Document#event:change:data editor.model.document#change:data} event. It is fired with an object containing the editor and the CKEditor 5 change:data event object.

<ckeditor [editor]="Editor" (change)="onChange($event)"></ckeditor>

import { ClassicEditor } from 'ckeditor5';
import { ChangeEvent } from '@ckeditor/ckeditor5-angular/ckeditor.component';

@Component( {
	// ...
} )
export class MyComponent {
	public Editor = ClassicEditor;

	public onChange( { editor }: ChangeEvent ) {
		const data = editor.getData();

		console.log( data );
	}
	// ...
}

`blur`

Fired when the editing view of the editor is blurred. It corresponds with the {@link module:engine/view/document~Document#event:blur editor.editing.view.document#blur} event. It is fired with an object containing the editor and the CKEditor 5 blur event data.

`focus`

Fired when the editing view of the editor is focused. It corresponds with the {@link module:engine/view/document~Document#event:focus editor.editing.view.document#focus} event. It is fired with an object containing the editor and the CKEditor 5 focus event data.

`error`

Fired when the editor crashes. Once the editor is crashed, the internal watchdog mechanism restarts the editor and fires the ready event.

Prior to ckeditor5-angular `v7.0.1`, this event was not fired for crashes during the editor initialization.

Integration with `ngModel`

The component implements the ControlValueAccessor interface and works with the ngModel. Here is how to use it:

Create some model in your component to share with the editor:

@Component( {
	// ...
} )
export class MyComponent {
	public model = {
		editorData: '<p>Hello, world!</p>'
	};
	// ...
}

Use the model in the template to enable a two–way data binding:

<ckeditor [(ngModel)]="model.editorData" [editor]="Editor"></ckeditor>

Styling

The CKEditor 5 rich text editor component for Angular can be styled using the component style sheet or using a global style sheet. See how to set the CKEditor 5 component's height using these two approaches.

Setting the height via the component style sheet

First, create a (S)CSS file in the parent component's directory and style the given editor's part preceded by the :host and ::ng-deep pseudo selectors:

/* src/app/app.component.css */

:host ::ng-deep .ck-editor__editable_inline {
	min-height: 500px;
}

Then in the parent component add the relative path to the above style sheet:

/* src/app/app.component.ts */

@Component( {
	// ...
	styleUrls: [ './app.component.css' ]
} )

Setting the height via a global style sheet

To style the component using a global style sheet, first, create it:

/* src/styles.css */

.ck-editor__editable_inline {
	min-height: 500px;
}

Then, add it in the angular.json configuration file:

"architect": {
	"build": {
		"options": {
			"styles": [
				{ "input": "src/styles.css" }
			]
		}
	}
}

Setting the placeholder

To display {@link features/editor-placeholder the placeholder} in the main editable element, set the placeholder field in the CKEditor 5 rich text editor component configuration:

@Component( {
	// ...
} )
export class MyComponent {
	public config = {
		placeholder: 'Type the content here!'
	}
}

Accessing the editor instance

The CKEditor 5 rich text editor component provides all the functionality needed for most use cases. When access to the full CKEditor 5 API is needed you can get the editor instance with an additional step.

To do this, create a template reference variable #editor pointing to the <ckeditor> component:

<ckeditor #editor [editor]="Editor"></ckeditor>

Then get the <ckeditor> component using a property decorated by @ViewChild( 'editor' ) and access the editor instance when needed:

@Component()
export class MyComponent {
	@ViewChild( 'editor' ) editorComponent: CKEditorComponent;

	public getEditor() {
		// Warning: This may return "undefined" if the editor is hidden behind the `*ngIf` directive or
		// if the editor is not fully initialised yet.
		return this.editorComponent.editorInstance;
	}
}

The editor creation is asynchronous so the `editorInstance` will not be available until the editor is created. If you want to make changes to an editor that has just been created, a better option would be getting the CKEditor 5 instance on the [`ready`](#ready) event.

How to?

Using the Document editor type

If you want to use the {@link framework/document-editor document (decoupled) editor}, you need to {@link module:editor-decoupled/decouplededitor~DecoupledEditor.create add the toolbar to the DOM manually}:

// app.component.ts

import { Component } from '@angular/core';
import { CKEditorModule } from '@ckeditor/ckeditor5-angular';
import { DecoupledEditor, Essentials, Italic, Paragraph, Bold, Undo } from 'ckeditor5';

import 'ckeditor5/ckeditor5.css';

@Component( {
	selector: 'app-root',
	templateUrl: './app.component.html',
	imports: [ CKEditorModule ],
	standalone: true
} )
export class AppComponent {
	title = 'angular';

	public Editor = DecoupledEditor;
	public config = {
		plugins: [ Bold, Essentials, Italic, Paragraph, Undo ],
		toolbar: [ 'undo', 'redo', '|', 'bold', 'italic' ]
	}
	public onReady( editor: DecoupledEditor ): void {
		const element = editor.ui.getEditableElement()!;
		const parent = element.parentElement!;

		parent.insertBefore(
			editor.ui.view.toolbar.element!,
			element
		);
	}
}

And then, link the method in the template:

<!-- app.component.html -->

<ckeditor [editor]="Editor" data="<p>Hello, world!</p>" (ready)="onReady($event)"></ckeditor>

Using the editor with collaboration plugins

We provide a few ready-to-use integrations featuring collaborative editing in Angular applications:

CKEditor 5 with real-time collaboration features
CKEditor 5 with real-time collaboration and revision history features
CKEditor 5 with the revision history feature
CKEditor 5 with the track changes feature

It is not mandatory to build applications on top of the above samples, however, they should help you get started.

Localization

CKEditor 5 supports multiple UI languages, and so does the official Angular component. Follow the instructions below to translate CKEditor 5 in your Angular application.

Similarly to CSS style sheets, both packages have separate translations. Import them as shown in the example below. Then, pass them to the translations array of the config property.

import { Component } from '@angular/core';
import { CKEditorModule } from '@ckeditor/ckeditor5-angular';
import { ClassicEditor } from 'ckeditor5';
// More imports...

import coreTranslations from 'ckeditor5/translations/es.js';
import premiumFeaturesTranslations from 'ckeditor5-premium-features/translations/es.js';

// style sheets imports...

@Component( {
	selector: 'app-root',
	templateUrl: './app.component.html',
	imports: [ CKEditorModule ],
	standalone: true
} )
export class AppComponent {
	title = 'angular';
	public Editor = ClassicEditor;
	public config = {
		translations: [ coreTranslations, premiumFeaturesTranslations ]
	}
}

For advanced usage see the {@link getting-started/setup/ui-language Setting the UI language} guide.
