Example code snippet to show/hide spinner

// showSpinner() will make the spinner visible
showSpinner(document.getElementById('container'));

// hideSpinner() method used hide spinner
hideSpinner(document.getElementById('container'));

Refer to the following example.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { DocumentEditorContainerModule } from '@syncfusion/ej2-angular-documenteditor'



import { Component, OnInit, ViewChild } from '@angular/core';
import { DocumentEditorContainerComponent, ImageFormat, ToolbarService } from '@syncfusion/ej2-angular-documenteditor';
import { showSpinner ,hideSpinner,createSpinner} from '@syncfusion/ej2-popups';

@Component({
imports: [
        
        DocumentEditorContainerModule
    ],


standalone: true,
      selector: 'app-container',
      // specifies the template string for the DocumentEditorContainer component
      template: `<button id='export'(click)="onClick(this)">Export</button><ejs-documenteditorcontainer  id="container" #documenteditor_default serviceUrl="https://services.syncfusion.com/angular/production/api/documenteditor/" height="600px" style="display:block" [enableToolbar]=true> </ejs-documenteditorcontainer>`,
      providers: [ToolbarService]
})
export class AppComponent implements OnInit {
    @ViewChild('documenteditor_default')
    public container?: DocumentEditorContainerComponent;

    ngOnInit(): void {
        createSpinner({
            // Specify the target for the spinner to show
              target: (document.getElementById('container') as HTMLElement) as HTMLElement
          });
    }
    onClick( args: any):void {
        // load your default document here
        let data: string= '{"sections":[{"sectionFormat":{"pageWidth":612,"pageHeight":792,"leftMargin":72,"rightMargin":72,"topMargin":72,"bottomMargin":72,"differentFirstPage":false,"differentOddAndEvenPages":false,"headerDistance":36,"footerDistance":36,"bidi":false},"blocks":[{"paragraphFormat":{"afterSpacing":30,"styleName":"Heading 1","listFormat":{}},"characterFormat":{},"inlines":[{"characterFormat":{},"text":"Adventure Works Cycles"}]}],"headersFooters":{"header":{"blocks":[{"paragraphFormat":{"listFormat":{}},"characterFormat":{},"inlines":[]}]},"footer":{"blocks":[{"paragraphFormat":{"listFormat":{}},"characterFormat":{},"inlines":[]}]}}}],"characterFormat":{"bold":false,"italic":false,"fontSize":11,"fontFamily":"Calibri","underline":"None","strikethrough":"None","baselineAlignment":"Normal","highlightColor":"NoColor","fontColor":"empty","fontSizeBidi":11,"fontFamilyBidi":"Calibri","allCaps":false},"paragraphFormat":{"leftIndent":0,"rightIndent":0,"firstLineIndent":0,"textAlignment":"Left","beforeSpacing":0,"afterSpacing":0,"lineSpacing":1.0791666507720947,"lineSpacingType":"Multiple","listFormat":{},"bidi":false},"defaultTabWidth":36,"trackChanges":false,"enforcement":false,"hashValue":"","saltValue":"","formatting":false,"protectionType":"NoProtection","dontUseHTMLParagraphAutoSpacing":false,"formFieldShading":true,"styles":[{"name":"Normal","type":"Paragraph","paragraphFormat":{"lineSpacing":1.149999976158142,"lineSpacingType":"Multiple","listFormat":{}},"characterFormat":{"fontFamily":"Calibri"},"next":"Normal"},{"name":"Default Paragraph Font","type":"Character","characterFormat":{}},{"name":"Heading 1 Char","type":"Character","characterFormat":{"fontSize":16,"fontFamily":"Calibri Light","fontColor":"#2F5496"},"basedOn":"Default Paragraph Font"},{"name":"Heading 1","type":"Paragraph","paragraphFormat":{"beforeSpacing":12,"afterSpacing":0,"outlineLevel":"Level1","listFormat":{}},"characterFormat":{"fontSize":16,"fontFamily":"Calibri Light","fontColor":"#2F5496"},"basedOn":"Normal","link":"Heading 1 Char","next":"Normal"},{"name":"Heading 2 Char","type":"Character","characterFormat":{"fontSize":13,"fontFamily":"Calibri Light","fontColor":"#2F5496"},"basedOn":"Default Paragraph Font"},{"name":"Heading 2","type":"Paragraph","paragraphFormat":{"beforeSpacing":2,"afterSpacing":6,"outlineLevel":"Level2","listFormat":{}},"characterFormat":{"fontSize":13,"fontFamily":"Calibri Light","fontColor":"#2F5496"},"basedOn":"Normal","link":"Heading 2 Char","next":"Normal"},{"name":"Heading 3","type":"Paragraph","paragraphFormat":{"leftIndent":0,"rightIndent":0,"firstLineIndent":0,"textAlignment":"Left","beforeSpacing":2,"afterSpacing":0,"lineSpacing":1.0791666507720947,"lineSpacingType":"Multiple","outlineLevel":"Level3","listFormat":{}},"characterFormat":{"fontSize":12,"fontFamily":"Calibri Light","fontColor":"#1F3763"},"basedOn":"Normal","link":"Heading 3 Char","next":"Normal"},{"name":"Heading 3 Char","type":"Character","characterFormat":{"fontSize":12,"fontFamily":"Calibri Light","fontColor":"#1F3763"},"basedOn":"Default Paragraph Font"},{"name":"Heading 4","type":"Paragraph","paragraphFormat":{"leftIndent":0,"rightIndent":0,"firstLineIndent":0,"textAlignment":"Left","beforeSpacing":2,"afterSpacing":0,"lineSpacing":1.0791666507720947,"lineSpacingType":"Multiple","outlineLevel":"Level4","listFormat":{}},"characterFormat":{"italic":true,"fontFamily":"Calibri Light","fontColor":"#2F5496"},"basedOn":"Normal","link":"Heading 4 Char","next":"Normal"},{"name":"Heading 4 Char","type":"Character","characterFormat":{"italic":true,"fontFamily":"Calibri Light","fontColor":"#2F5496"},"basedOn":"Default Paragraph Font"},{"name":"Heading 5","type":"Paragraph","paragraphFormat":{"leftIndent":0,"rightIndent":0,"firstLineIndent":0,"textAlignment":"Left","beforeSpacing":2,"afterSpacing":0,"lineSpacing":1.0791666507720947,"lineSpacingType":"Multiple","outlineLevel":"Level5","listFormat":{}},"characterFormat":{"fontFamily":"Calibri Light","fontColor":"#2F5496"},"basedOn":"Normal","link":"Heading 5 Char","next":"Normal"},{"name":"Heading 5 Char","type":"Character","characterFormat":{"fontFamily":"Calibri Light","fontColor":"#2F5496"},"basedOn":"Default Paragraph Font"},{"name":"Heading 6","type":"Paragraph","paragraphFormat":{"leftIndent":0,"rightIndent":0,"firstLineIndent":0,"textAlignment":"Left","beforeSpacing":2,"afterSpacing":0,"lineSpacing":1.0791666507720947,"lineSpacingType":"Multiple","outlineLevel":"Level6","listFormat":{}},"characterFormat":{"fontFamily":"Calibri Light","fontColor":"#1F3763"},"basedOn":"Normal","link":"Heading 6 Char","next":"Normal"},{"name":"Heading 6 Char","type":"Character","characterFormat":{"fontFamily":"Calibri Light","fontColor":"#1F3763"},"basedOn":"Default Paragraph Font"}],"lists":[],"abstractLists":[],"comments":[],"revisions":[],"customXml":[]}';

        // showSpinner() will make the spinner visible
        showSpinner((document.getElementById('container') as HTMLElement) as HTMLElement);
        // Open the default document
        (this.container as DocumentEditorContainerComponent ).documentEditor.open(data);
        setInterval(function(){

            // hideSpinner() method used hide spinner
            hideSpinner((document.getElementById('container') as HTMLElement));

        }, 5000);
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Note: In above example, we have used setInterval to hide spinner, just for demo purpose.
