Opening a document in WebViewer from Blob

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

WebViewer(...)
  .then(instance => {
    // `myBlob` is your blob data which can come
    // from sources such as a server or the filesystem
    instance.UI.loadDocument(myBlob, { filename: 'myfile.pdf' });

    const { documentViewer } = instance.Core;
    documentViewer.addEventListener('documentLoaded', () => {
      // perform document operations
    });
  });

See more WebViewer events such as documentLoaded to understand when to execute API operations.
