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

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
       } 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]
})
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 { LinkAnnotationService, BookmarkViewService, MagnificationService,
         ThumbnailViewService, ToolbarService, NavigationService,
         AnnotationService, TextSearchService, TextSelectionService,
         PrintService
       } 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"
                       [serviceUrl]='service'
                       [documentPath]='document'
                       style="height:640px;display:block">
                </ejs-pdfviewer>
             </div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               AnnotationService, TextSearchService, TextSelectionService,
               PrintService]
})
export class AppComponent implements OnInit {
  public service = 'https://ej2services.syncfusion.com/production/web-services/api/pdfviewer';
  public document = 'PDF_Succinctly.pdf';
  ngOnInit(): void {
  }
}

Run the application

Use the following command to run the application in browser.

ng serve --open

The output will appear as follows.

import { Component, OnInit } from '@angular/core';
import {
  LinkAnnotationService, BookmarkViewService, MagnificationService, ThumbnailViewService,
  ToolbarService, NavigationService, AnnotationService, TextSearchService, TextSelectionService, PrintService
} 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" [serviceUrl]='service' [documentPath]='document' style="height:640px;display:block"></ejs-pdfviewer>
</div>`,
  providers: [LinkAnnotationService, BookmarkViewService, MagnificationService,
    ThumbnailViewService, ToolbarService, NavigationService, AnnotationService, TextSearchService, TextSelectionService, PrintService]
})
export class AppComponent implements OnInit {
    public service = 'https://ej2services.syncfusion.com/production/web-services/api/pdfviewer';
    public document = 'PDF_Succinctly.pdf';
    ngOnInit(): void {
    }
}
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { PdfViewerModule, LinkAnnotationService, BookmarkViewService, MagnificationService, ThumbnailViewService,
  ToolbarService, NavigationService, TextSearchService, TextSelectionService, PrintService  } from '@syncfusion/ej2-angular-pdfviewer';


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

@NgModule({
  imports: [ BrowserModule , PdfViewerModule ],
  declarations: [ AppComponent ],
  bootstrap: [AppComponent],
  providers: [LinkAnnotationService, BookmarkViewService, MagnificationService,
    ThumbnailViewService, ToolbarService, NavigationService, TextSearchService, TextSelectionService, PrintService]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
