This section explains the steps required to create a simple Standalone Angular PDF Viewer in Angular 17 and above with –no-standalone flag.

Setup Angular Environment

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

npm install -g @angular/cli

Create an Angular Application

Start a new Angular application using the Angular CLI command as follows.

ng new my-app --no-standalone
cd my-app

Installing Syncfusion PDF Viewer package

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

To install PDF Viewer component, use the following command.

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

Copy the contents of the ej2-pdfviewer-lib folder from ./node_modules/@syncfusion/ej2-pdfviewer/dist to the src/assets directory using the command:

cp -R ./node_modules/@syncfusion/ej2-pdfviewer/dist/ej2-pdfviewer-lib  src/assets/ej2-pdfviewer-lib

Confirm that there is an ‘ej2-pdfviewer-lib’ directory within your public directory, housing the assets of the PDF Viewer library.
Validate that your server has been configured to utilize the Content-Type: application/wasm MIME type. Additional information can be found in the Troubleshooting section.

Registering PDF Viewer Module

Import PDF Viewer module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-pdfviewer [src/app/app.module.ts].

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
// import the PdfViewer Module for the PDF Viewer component
import { PdfViewerModule, LinkAnnotationService, BookmarkViewService,
         MagnificationService, ThumbnailViewService, ToolbarService,
         NavigationService, TextSearchService, TextSelectionService,
         PrintService, FormDesignerService, FormFieldsService, 
         AnnotationService, PageOrganizerService } from '@syncfusion/ej2-angular-pdfviewer';
import { AppComponent } from './app.component';

@NgModule({
  //declaration of ej2-angular-pdfviewer module into NgModule
  imports: [BrowserModule, PdfViewerModule],
  declarations: [AppComponent],
  bootstrap: [AppComponent],
   providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               TextSearchService, TextSelectionService, PrintService,
               AnnotationService, FormDesignerService, FormFieldsService, PageOrganizerService]
})
export class AppModule { }

Adding CSS reference

Add the Angular PDF Viewer component’s styles as given below in src/styles.css file.

@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-dropdowns/styles/material.css';
@import '../node_modules/@syncfusion/ej2-inputs/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-splitbuttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-pdfviewer/styles/material.css';
@import '../node_modules/@syncfusion/ej2-notifications/styles/material.css';

Adding PDF Viewer component

Add the Angular PDF Viewer by using <ejs-pdfviewer> selector in template section of the src/app/app.component.ts file to render the PDF Viewer component.

import { Component, OnInit } from '@angular/core';
import { PdfViewerModule, LinkAnnotationService, BookmarkViewService,
         MagnificationService, ThumbnailViewService, ToolbarService,
         NavigationService, TextSearchService, TextSelectionService,
         PrintService, FormDesignerService, FormFieldsService, 
         AnnotationService, PageOrganizerService } from '@syncfusion/ej2-angular-pdfviewer';

@Component({
  selector: 'app-root',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
                <ejs-pdfviewer id="pdfViewer"
                    [documentPath]='document'
                    [resourceUrl]='resource' 
                    style="height:640px;display:block">
                </ejs-pdfviewer>
             </div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               TextSearchService, TextSelectionService, PrintService,
               AnnotationService, FormDesignerService, FormFieldsService, PageOrganizerService]
})
export class AppComponent implements OnInit {
  public document: string = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';
  public resource: string = "https://cdn.syncfusion.com/ej2/26.2.11/dist/ej2-pdfviewer-lib";
  ngOnInit(): void {
  }
}

Run the application

Use the following command to run the application in browser.

ng serve --open

The output will appear as follows.

app.component.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { PdfViewerModule, LinkAnnotationService, BookmarkViewService,
         MagnificationService, ThumbnailViewService, ToolbarService,
         NavigationService, TextSearchService, TextSelectionService,
         PrintService, FormDesignerService, FormFieldsService, 
         AnnotationService, PageOrganizerService } from '@syncfusion/ej2-angular-pdfviewer';

@Component({
  selector: 'app-container',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
  <ejs-pdfviewer 
    id="pdfViewer" 
    [documentPath]='document' 
    [resourceUrl]='resource' 
    style="height:640px;display:block">
  </ejs-pdfviewer>
</div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               TextSearchService, TextSelectionService, PrintService,
               AnnotationService, FormDesignerService, FormFieldsService, PageOrganizerService]
})
export class AppComponent implements OnInit {
    public document = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';
    public resource: string = "https://cdn.syncfusion.com/ej2/26.2.11/dist/ej2-pdfviewer-lib";
    ngOnInit(): void {
    }
}
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';


platformBrowserDynamic().bootstrapModule(AppModule)
  .catch(err => console.error(err));
