Open a document from Blob

If your document is already in Blob format you can pass the Blob object directly to loadDocument function.

WebViewer(...)
  .then(instance => {
    instance.loadDocument(myBlob, { filename: 'myfile.pdf' });

    const { docViewer } = instance;
    docViewer.on('documentLoaded', () => {
      // perform document operations
    });
  });
