I\'m having troubles in finding a solution for this: I retrieve a PDF blob from a SQL filestream field using Javascript in this way (it\'s a lightswitch project)

Answer 1

I am using viewer in an iframe;

And fetch API used as follows;

 fetch(pdfSourceUrl).then((response: Response) => {
            response.blob().then((blob) => {
              var url = URL.createObjectURL(blob);
              pdfIframe.src = `pdfjs/web/viewer.html?file=${url}`;
            });
          });

Eventually iframe src created as follows;

http://localhost:9000/pdfjs/web/viewer.html?file=blob:http://localhost:9000/14f6a2ec-ad25-40ab-9db8-560c15e90f6e
