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.

1WebViewer(...)
2  .then(instance => {
3    // `myBlob` is your blob data which can come
4    // from sources such as a server or the filesystem
5    instance.UI.loadDocument(myBlob, { filename: 'myfile.pdf' });
6
7    const { documentViewer } = instance.Core;
8    documentViewer.addEventListener('documentLoaded', () => {
9      // perform document operations
10    });
11  });
