Detailed description of issue
I have a chrome extension in an iframe, and I want to load the pdf viewer in sidebar
We render react app in a extension which is a sidebar basically


The issue is, how can i set up license key which would support this behavior? I tried with chrome-extension//unique id it did not work, how can i overcome this issue?

Expected behaviour
A user can view pdf in sidebar at any given moment at any website.

Does your issue happen with every document, or just one?
We have a web app as well it works in fine there but we need this to integrate with our extension as well

Link to document
{Provide a link to the document in question if possible}

Code snippet


export const PDFViewer = ({url, name, size}: IPDFViewer) => {
  const viewer = useRef(null);
  useEffect(() => {
    const initializeWebViewer = async (blob: Blob) => {
      try {
        const instance = await WebViewer(
          {
            path: '/',
            licenseKey: 'license-key',
          },
          viewer.current
        );
        blob &&
          (await instance.UI.loadDocument(blob, {
            filename: name,
          }));
        instance.setLayoutMode(instance.LayoutMode.Single);
        // stops inline executing of js
        instance.Core.disableEmbeddedJavaScript();
      } catch (e) {
        logging.capture(e);
      }
    };

    const loadPdf = async () => {
      const file = await fetchAsset(url);

      initializeWebViewer(file);
    };

    loadPdf();
  }, [url]);
  return <Box ref={viewer} {...sizes[size]} w='100%' flexShrink={0} />;
};

Hello usman,

The license key is tied to a domain, therefore if its running on the domain it should be fine.

Hi @tgordon
The chrome extension can be opened in any domain (google,youtube,etc). I cant create license keys for all. Is there any work around for such cases?

Hello usman,

The license has to be tied to a specific domain, wherever your server is that is hosting the files should be the domain you’re using.
