The Essential JS 2 for JavaScript (global script) is an ES5 formatted pure JavaScript framework which can be directly used in latest web browsers.

Step 1: Create an app folder my-app for the Essential JS 2 JavaScript components.

Step 2: The Essential JS 2 component’s global scripts and styles are already hosted in the below CDN link formats.

Syntax:

Script: https://cdn.syncfusion.com/ej2/{Version}/dist/{PACKAGE_NAME}.min.js

Styles: https://cdn.syncfusion.com/ej2/{Version}/{PACKAGE_NAME}/styles/material.css

Example:

Script: https://cdn.syncfusion.com/ej2/26.2.11/dist/ej2.min.js

Styles: https://cdn.syncfusion.com/ej2/26.2.11/ej2-base/styles/material.css

Step 3: Create a HTML page (index.html) in my-app location and add the CDN link references. Now, add the Div element and initiate the Essential JS 2 PDF Viewer component in the index.html by using following code.

<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head>
     <title>Essential JS 2</title>
     <!-- Essential JS 2 material theme -->

     <link href="https://cdn.syncfusion.com/ej2/29.2.4/ej2-splitbuttons/styles/material.css" rel="stylesheet">

     <body>
          <!--element which is going to render-->
          <div id="container">
               <div id="PdfViewer" style="height:580px;width:100%;"></div>
          </div>
          <script>                
               //Initialize PDF Viewer component
               var pdfviewer = new ej.pdfviewer.PdfViewer({
                    documentPath:'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf',
                    resourceUrl:'https://cdn.syncfusion.com/ej2/29.2.4/dist/ej2-pdfviewer-lib'
               });
               ej.pdfviewer.PdfViewer.Inject(ej.pdfviewer.TextSelection, ej.pdfviewer.TextSearch, ej.pdfviewer.Print, ej.pdfviewer.Navigation, ej.pdfviewer.Toolbar,ej.pdfviewer.Magnification, ej.pdfviewer.Annotation, ej.pdfviewer.FormDesigner, ej.pdfviewer.FormFields, ej.pdfviewer.PageOrganizer);
               
               //PDF Viewer control rendering starts
               pdfviewer.appendTo('#PdfViewer');
          </script>       
	     <script>
			var ele = document.getElementById('container');
			if(ele) {
				ele.style.visibility = "visible";
			}   
        </script>
</body></html>

Steps to Load PDF Viewer with Local Resources

To use local resources with your PDF Viewer, follow these steps:

Step 1: Ensure that your application includes the ej2-pdfviewer-lib folder. This folder must contain the pdfium.js, pdfium.wasm files, and the PDF file that you intend to display. These should reside in the same location as the ej2.min.js script and its related styles.

Step 2: Assign local file paths to the documentPath and resourceUrl properties within the PDF Viewer setup. The documentPath should refer to your PDF file, while the resourceUrl should point to the directory containing the supporting resources.

Step 3: Insert the necessary script and style references within the <head> section of your HTML file. Make sure these point to your local copies of the files instead of CDN links.

By following these steps, you will configure your PDF Viewer to load the required resources locally. See the code snippet below for reference.

<script>

var pdfviewer = new ej.pdfviewer.PdfViewer({
    documentPath:window.location.origin +'/resources/pdfsuccinctly.pdf',
    resourceUrl:window.location.origin +'/resources/ej2-pdfviewer-lib'
});
            
</script>

Step 4: Now, run the index.html in web browser, it will render the Essential JS 2 PDF Viewer component.
