Note

The complete sample project How to use the Web Document Viewer in JavaScript with Vue is available in the DevExpress Examples repository.

The server-side model stores reports that can be rendered in the HTML5 Document Viewer integrated in the Vue JavaScript application.

This project consists of the following server and client parts:

Server (Back-End) Application

Review the following topics to create a back-end application:

• Document Viewer Server-Side Application (ASP.NET MVC)
• Document Viewer Server-Side Application (ASP.NET Core)

Client (Front-End) Application

Create a folder to store application files. Use the command prompt and perform the following steps to create and configure the client part:

1. Ensure you have the current Node.js versions with NPM installed on your machine.

   node -v
   npm -v
   

2. Install the Vue CLI (command line interface tool) globally:

   npm install -g @vue/cli
   

3. Create a Vue application with a default preset and navigate to the created folder:

   vue create vue-report-viewer
   

   cd vue-report-viewer
   

4. Install DevExpress packages:

   npm install devextreme @devexpress/analytics-core devexpress-reporting
   

5. Create the src/components/WebDocumentViewer.vue file with the following content:

   WebDocumentViewer.vue

   <template>
   <div ref="viewer" style="position: absolute; left: 0; right: 0; top: 0; bottom: 0" data-bind="dxReportViewer: $data"></div>
   </template>
   
   <script>
   import ko from "knockout";
   import 'devexpress-reporting/dx-webdocumentviewer';
   
   export default {
   name: "WebDocumentViewer",
   mounted() {
       var viewerOptions = {
           reportUrl: ko.observable("Products"), // The URL of a report.
           requestOptions: {
           host: "https://localhost:54114/",
       // Use this line for the ASP.NET MVC backend
       //invokeAction: "/WebDocumentViewer/Invoke"
       // Use this line for the ASP.NET Core backend
       invokeAction: "DXXRDV"
           }
       };
       ko.applyBindings(viewerOptions, this.$refs.viewer);
   },
   beforeDestroy() {
       ko.cleanNode(this.$refs.viewer);
   }
   };
   </script>
   

   Important

   In the code above, set the host port number to your back-end application’s server port number.

6. Open the src/App.vue file and replace its content with the following code to display the Web Document Viewer component on the page:

   App.vue

   <template>
   <div>
       <WebDocumentViewer />
   </div>
   </template>
   
   <script>
   import WebDocumentViewer from './components/WebDocumentViewer';
   
   export default {
   name: 'app',
   components: {
       WebDocumentViewer
   }
   }
   </script>
   

7. Add styles to the file src/main.js:

   main.js

   import "jquery-ui/themes/base/all.css";
   import "devextreme/dist/css/dx.common.css";
   import "devextreme/dist/css/dx.light.css";
   import "@devexpress/analytics-core/dist/css/dx-analytics.common.css";
   import "@devexpress/analytics-core/dist/css/dx-analytics.light.css";
   import "devexpress-reporting/dist/css/dx-webdocumentviewer.css";
   

8. Run the application:

   npm run serve
   

9. Open the http://localhost:8080/ location in browser to see the test report.
