Getting Started with the KendoReact PDF Viewer

This guide provides essential information about using the KendoReact PDF Viewer package. You will learn how to install the PDF Viewer package, add a PDF Viewer component to your project, style the component, and activate your license.

After completing this guide, you will be able to reproduce the following example.

Setting Up Your React Project

Before you install the KendoReact PDF Viewer, make sure that you have a running React project. The easiest way to set up a project for the KendoReact components is to use the create-kendoreact-app tool that is described in the Get Started with KendoReact article.

Installing the PDF Viewer Package

All KendoReact packages are distributed through npm and offer a similar installation experience. To use the PDF Viewer component, start with the installation of the PDF Viewer npm package and its dependencies. Use Node.js v5.0.0 or later.

Copy Codenpm install --save @progress/kendo-react-pdf-viewer @progress/kendo-data-query @progress/kendo-drawing @progress/kendo-file-saver @progress/kendo-react-animation @progress/kendo-react-buttons @progress/kendo-react-data-tools @progress/kendo-react-dateinputs @progress/kendo-react-dropdowns @progress/kendo-react-indicators @progress/kendo-react-inputs @progress/kendo-react-intl @progress/kendo-react-progressbars @progress/kendo-react-treeview @progress/kendo-react-upload @progress/kendo-licensing @progress/kendo-svg-icons

When using the component with Next.js, it will also be required to install the node-loader library and load it to the webpack in next.config.js as demonstrated below. In addition, depending on the configuration, it might also be needed to install the canvas dependency:

Copy Codeconst nextConfig = {
  webpack: (config, { dev, isServer, webpack, nextRuntime }) => {
    config.module.rules.push({
      test: /\.node$/,
      loader: "node-loader"
    });
    return config;
  }
}

Importing the Component

After installing the package, import the PDF Viewer component in the React App.

In the src/App.js file of your React project, import the PDFViewer component from the PDF Viewer package.

Copy Code// ES2015 module syntax
import { PDFViewer } from '@progress/kendo-react-pdf-viewer';

Copy Code// CommonJS format
const { PDFViewer } = require('@progress/kendo-react-pdf-viewer');

Using the Component

1. After installing the PDF Viewer package and importing the components, add the PDFViewer tag to the App component file of your React project (for example, src/App.js).

2. Set the url prop to a local PDF file in order to display initial PDF content in the viewer.

   Copy Codefunction PDFViewerContainer() {
       return (
         <>
           <PDFViewer url="sample.pdf"/>
         </>
       );
   }
   
   ReactDOM.render(
     <PDFViewerContainer />,
     document.getElementById('app')
   );

3. To style the PDF Viewer, install and import the Default theme, which is one of the three beautiful themes for KendoReact.

   3.1. Install the Default theme package.

   Copy Codenpm install --save @progress/kendo-theme-default

   3.2. Import the CSS file from the package in src/App.js. Add this import before your existing App.css import.

   Copy Codeimport '@progress/kendo-theme-default/dist/all.css';

4. Build and run the application by typing the following command in the root folder of your project:

   Copy Codenpm start

5. Navigate to http://localhost:3000 to see the KendoReact PDF Viewer component on the page.

Activating Your License Key

Using any of the UI components in the KendoReact library requires either a commercial license key or an active trial license key.

Follow the instructions on the KendoReact My License page to activate your trial or commercial license. You can skip this step if your application already contains a KendoReact license file.
