    npm version

    March 30, 2022:

    Note this repository will be no longer be maintained by the original developers. We encourage all users to switch to clover-iiif, which will provide the same image viewing experience in OpenSeadragon, along with support for audio and video files in a single viewer.

    Updated viewer

    Image of OpenSeadragon React Viewer

    A React wrapper component around the OpenSeadragon viewer. Feed OpenSeadragonViewer a IIIF manifest URL, and it will render an OpenSeadragon viewer with:

    • FontAwesome toolbar icons
    • A tile source dropdown navigation menu
    • Thumbnails navigation
    • Download options
    • Support for deep linking, and saving URL parameters

    Installation and usage

    npm install openseadragon-react-viewer
    
    // And peer dependencies
    npm install @emotion/react openseadragon react-device-detect react-select

    Then use it in your app:

    import React from "react";
    import { OpenSeadragonViewer } from "openseadragon-react-viewer";
    
    const App = () => {
      // Provide either a local IIIF manifest object
      const manifest = MY_AWESOME_MANIFEST;
    
      // Or, provide a publicly accessible URL of a IIIF manifest
      const manifestUrl = "https://some-manifest-url-here.json";
    
      // Options to show/hide extra UI features in the viewer
      // height(in pixels) option is default to 800 for wide-screens and 500 for narrow-screens
      // All other options default to 'true'
      const options = {
        showDropdown: true,
        showThumbnails: true,
        showToolbar: true,
        deepLinking: true,
        height: 800,
      };
    
      // Pass through any OpenSeadragon config options you'd like to override
      const openSeadragonOptions = {
        gestureSettingsMouse: {
          scrollToZoom: true,
        },
      };
    
      // Customize which tool bar controls are displayed
      const toolBarOptions = {
        showZoom: true,
        showFullScreen: true,
        showDownload: true,
        showPreviousNext: true,
      };
    
      // Note: A local manifest will take precedence over manifestUrl if both props are supplied
      return (
        <OpenSeadragonViewer
          manifest={manifest}
          manifestUrl={manifestUrl}
          options={options}
          openSeadragonOptions={openSeadragonOptions} // Optional
          toolBarOptions={toolBarOptions} // Optional
        />
      );
    };
    
    export default App;

    Cross-site Requests

    ** This info pulled from the Diva.js package**

    You may receive an error that looks something like this:

    XMLHttpRequest cannot load http://example.com/demo/imagefiles.json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8000' is therefore not allowed access.

    This is a security precaution that all browsers use to prevent cross-site request forgeries. If you receive this message it is because your manifestUrl prop and the server used to serve the OpenSeadragon React Viewer are not at the same server address.

    To fix this you must ensure that the OpenSeadragon React Viewer host's React application, and the location pointed to by the manifestUrl prop are being served by the same server, or you must create an exception using the Access-Control-Allow-Origin header on your server to explicitly white-list the manifestUrl location.
