This example incorporates the Web Document Viewer into a client-side app built with React. The example consists of two parts:
-
The ServerSideApp folder contains the backend project. The project is an ASP.NET Core application that enables cross-domain requests (CORS) (Access-Control-Allow-Origin) and implements custom web report storage.
-
The react-document-viewer folder contains the client application built with React.
In the ServerSideApp/ServerSideApp folder, run the following command:
dotnet run
The server starts at http://localhost:5000. To debug the server, run the application in Visual Studio.
In the react-document-viewer folder, run the following commands:
npm install
npm run dev
Open http://localhost:3000/ in your browser to view the result. The application displays the Web Document Viewer with the TestReport report.
