Downloading multiple documents

Hi there, I wanted to see if there was any way to easily download a group of different PDFs via the front end. We’re using an Angular app… so far I’ve had luck with using this code to generate a PDF download for the current document loaded:

const { docViewer, annotManager } = this.wvInstance;
const doc = docViewer.getDocument();
const xfdfString = await annotManager.exportAnnotations();

const options = {
downloadType: ‘pdf’
const data = await doc.getFileData(options);
const arr = new Uint8Array(data);
const blob = new Blob([arr], { type: ‘application/pdf’ });

I’m starting to look into how this could be altered so that I can generate blobs for other PDFs that are not currently loaded in the instance. Any help would be much appreciated!

Hello ,

If you want to download a group of different PDFs, can you use window.fetch API to download the documents as blobs? If so, then I found this stack overflow post with some sample code:

let me know if you have more questions.
