This section explains the steps required to create a simple Angular Rich Text Editor component and configure its available functionalities.

To get start quickly with Angular Rich Text Editor using CLI and Schematics, you can check on this video:

Setup Angular Environment

You can use Angular CLI to setup your Angular applications. To install Angular CLI use the following command.

npm install -g @angular/cli@16.0.1

Create an Angular Application

Start a new Angular application using below Angular CLI command.

ng new my-app

This command will prompt you for a few settings for the new project, such as whether to add Angular routing and which stylesheet format to use.

By default, it will create a CSS-based application.

Next, navigate to the created project folder:

cd my-app

Adding Syncfusion Rich Text Edior package

All the available Essential JS 2 packages are published in npmjs.com registry.

To install Rich Text Editor component, use the following command.

npm install @syncfusion/ej2-angular-richtexteditor --save

The –save will instruct NPM to include the rich text editor package inside of the dependencies section of the package.json.

Adding CSS reference

The following CSS files are available in ../node_modules/@syncfusion package folder.
This can be referenced in [src/styles.css] using following code.

  @import '../../node_modules/@syncfusion/ej2-base/styles/material.css';
  @import '../../node_modules/@syncfusion/ej2-icons/styles/material.css';
  @import '../../node_modules/@syncfusion/ej2-buttons/styles/material.css';
  @import '../../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css';
  @import '../../node_modules/@syncfusion/ej2-inputs/styles/material.css';
  @import '../../node_modules/@syncfusion/ej2-lists/styles/material.css';
  @import '../../node_modules/@syncfusion/ej2-navigations/styles/material.css';
  @import '../../node_modules/@syncfusion/ej2-popups/styles/material.css';
  @import '../../node_modules/@syncfusion/ej2-dropdowns/styles/material.css';
  @import '../../node_modules/@syncfusion/ej2-richtexteditor/styles/material.css';

Adding Rich Text Editor component

Modify the template in the [src/app/app.component.ts] file to render the Rich Text Editor component. Add the Angular Rich Text Editor by using the <ejs-richtexteditor> selector in the template section of the app.component.ts file.

import { Component } from '@angular/core';
import { ToolbarService, LinkService, ImageService, HtmlEditorService } from '@syncfusion/ej2-angular-richtexteditor';
import { RichTextEditorAllModule } from '@syncfusion/ej2-angular-richtexteditor'
@Component({
  imports: [
    RichTextEditorAllModule
  ],
  standalone: true,
  selector: 'app-root',
  template: `<ejs-richtexteditor id='defaultRTE' [value]="value"></ejs-richtexteditor>`,
  providers: [ToolbarService, LinkService, ImageService, HtmlEditorService]
})

export class AppComponent {
  public value:string = `<p>The Syncfudion Rich Text Editor, a WYSIWYG (what you see is what you get) editor, is a user interface that allows you to create, edit, and format rich text content. You can try out a demo of this editor here.</p><p><b>Key features:</b></p><ul>
    <li>
        <p>Provides &lt;IFRAME&gt; and &lt;DIV&gt; modes.</p>
    </li>
    <li>
        <p>Bulleted and numbered lists.</p>
    </li>
    <li>
        <p>Handles images, hyperlinks, videos, hyperlinks, uploads, etc.</p>
    </li>
    <li>
        <p>Contains undo/redo manager. </p>
    </li>
  </ul><div style="display: inline-block; width: 60%; vertical-align: top; cursor: auto;"><img alt="Sky with sun" src="https://cdn.syncfusion.com/ej2/richtexteditor-resources/RTE-Overview.png" width="309" style="min-width: 10px; min-height: 10px; width: 309px; height: 174px;" class="e-rte-image e-imginline e-rte-drag-image" height="174" /></div>  `;
}

Module Injection

To create Rich Text Editor with additional features, inject the required modules. The following modules are used to extend Rich Text Editor’s basic functionality.

• HtmlEditor - Inject this module to use Rich Text Editor as html editor.
• Image - Inject this module to use image feature in Rich Text Editor.
• Link - Inject this module to use link feature in Rich Text Editor.
• QuickToolbar - Inject this module to use quick toolbar feature for the target element.
• Toolbar - Inject this module to use Toolbar feature.

These modules should be injected into the providers section of root NgModule or component class.

Additional feature modules are available here.

Configure the Toolbar

Configure the toolbar with custom tools using items field of toolbarSettings property in your application.

app.component.ts

import { RichTextEditorAllModule } from '@syncfusion/ej2-angular-richtexteditor'
import { DialogModule } from '@syncfusion/ej2-angular-popups'
import { Component } from '@angular/core';
import { ToolbarService, LinkService, ImageService, HtmlEditorService } from '@syncfusion/ej2-angular-richtexteditor';

@Component({
imports: [
        RichTextEditorAllModule,
        DialogModule
    ],
  standalone: true,
  selector: 'app-root',
  template: `<ejs-richtexteditor id='rteTool' [toolbarSettings]='tools' [value]="value" >
  </ejs-richtexteditor>`,
  providers: [ToolbarService, LinkService, ImageService, HtmlEditorService]
})

export class AppComponent {
  public tools: object = {
      items: ['Undo', 'Redo', '|',
          'Bold', 'Italic', 'Underline', 'StrikeThrough', '|',
          'FontName', 'FontSize', 'FontColor', 'BackgroundColor', '|',
          'SubScript', 'SuperScript', '|',
          'LowerCase', 'UpperCase', '|',
          'Formats', 'Alignments', '|', 'OrderedList', 'UnorderedList', '|',
          'Indent', 'Outdent', '|', 'CreateLink',
          'Image', '|', 'ClearFormat', 'Print', 'SourceCode', '|', 'FullScreen']
  };
  
  public value:string = `<p>The Syncfudion Rich Text Editor, a WYSIWYG (what you see is what you get) editor, is a user interface that allows you to create, edit, and format rich text content. You can try out a demo of this editor here.</p><p><b>Key features:</b></p><ul>

   </li>
   <li>
      <p>Handles images, hyperlinks, videos, hyperlinks, uploads, etc.</p>
   </li>
   <li>
      <p>Contains undo/redo manager. </p>
   </li>
</ul><div style="display: inline-block; width: 60%; vertical-align: top; cursor: auto;"><img alt="Sky with sun" src="https://cdn.syncfusion.com/ej2/richtexteditor-resources/RTE-Overview.png" width="309" style="min-width: 10px; min-height: 10px; width: 309px; height: 174px;" class="e-rte-image e-imginline e-rte-drag-image" height="174" /></div>  `;

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Insert images and links

The image module inserts an image into Rich Text Editor’s content area, and the link module links external resources such as website URLs, to selected text in the Rich Text Editor’s content, respectively.

The link inject module adds a link icon to the toolbar and the image inject module adds an image icon to the toolbar.

Specifies the items to be rendered in the quick toolbar based on the target element such image, link, and text element. The quick toolbar opens to customize the element by clicking the target element.

app.component.ts

import { RichTextEditorAllModule } from '@syncfusion/ej2-angular-richtexteditor'
import { DialogModule } from '@syncfusion/ej2-angular-popups'
import { Component } from '@angular/core';
import { ToolbarService, LinkService, ImageService, HtmlEditorService, QuickToolbarService } from '@syncfusion/ej2-angular-richtexteditor';
@Component({
    imports: [
            RichTextEditorAllModule,
            DialogModule
        ],
    standalone: true,
    selector: 'app-root',
    template: `<ejs-richtexteditor id='defaultRTE' [value]="value" [toolbarSettings]='tools' [quickToolbarSettings]='quickTools'></ejs-richtexteditor>`,
    providers: [ToolbarService, LinkService, ImageService, HtmlEditorService, QuickToolbarService]
})
export class AppComponent  {
    public tools: object = {
        items: ['Undo', 'Redo', '|',
            'Bold', 'Italic', 'Underline', 'StrikeThrough', '|',
            'FontName', 'FontSize', 'FontColor', 'BackgroundColor', '|',

            'LowerCase', 'UpperCase', '|',
            'Formats', 'Alignments', '|', 'OrderedList', 'UnorderedList', '|',
            'Indent', 'Outdent', '|', 'CreateLink',
            'Image', '|', 'ClearFormat', 'Print', 'SourceCode', '|', 'FullScreen']
    };
    public quickTools: object = {
        image: [
            'Replace', 'Align', 'Caption', 'Remove', 'InsertLink', '-', 'Display', 'AltText', 'Dimension']
    };

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Run the application

Use the following command to run the application in the browser.

ng serve --open

Retrieve the formatted content

To retrieve the editor contents, use the value property of Rich Text Editor.

  let rteValue: string = this.rteObj.value;

Or, you can use the getHtml public method to retrieve the Rich Text Editor content.

  let rteValue: string = this.rteObj.getHtml();

To fetch the Rich Text Editor’s text content, use getText method.

  
  let rteValue: string = this.rteObj.contentModule.getText();

Retrieve the number of characters in the Rich Text Editor

To get the maximum number of characters in the Rich Text Editor’s content, use getCharCount

  let rteCount: number = this.rteObj.getCharCount();
