How to Handle Line Breaks in Rich Text Editor for Angular?

When using the Angular Rich Text Editor, text retrieved from an API that contains \n characters may not automatically render as new lines. Instead, these characters need to be converted to HTML <br> tags.

This article provides a comprehensive guide to implementing this conversion to ensure correct rendering of line breaks in the rich text editor.

Rich Text Editor Implementation

The core approach involves replacing \n characters with <br> tags in the value string before it is set to the Rich Text Editor. This ensures that line breaks are displayed correctly as HTML content.

1. HTML Template Configuration: Reference the rich text editor and include a button to trigger the value change:

<ejs-richtexteditor #rteInstance>
  <ng-template #valueTemplate>
    <p>entered first</p>
  </ng-template>
</ejs-richtexteditor>
<div>
  <button class="e-btn" (click)="onclick()">Change Value</button>
</div>

2. Modify the Component:

Update your Angular component so that when you set the editor’s value, \n is replaced with <br>. This allows the text to be correctly interpreted and displayed with line breaks in the HTML context.

import { RichTextEditorComponent,} from '@syncfusion/ej2-angular-richtexteditor';

export class AppComponent {
  @ViewChild('rteInstance')
  public rteObj: RichTextEditorComponent;

  onclick(): void {
    let value ='<b>Bold</b>\n<i>Italic</i>\n<b><i>Bold Italic</i></b>\n<b>';
    // Convert \n to <br> for HTML rendering
    this.rteObj.value = value.replace(/\n/g, '<br>');
  }
}

By implementing the above steps, you can manage and render text with correct line breaks in the Syncfusion Rich Text Editor, ensuring content from APIs is displayed in the intended format.
