Hey! I have two remarks, I think:

  • there's no need to append the 'link' to the body (unless you need it there?)
  • we should release the created URLObject by window.URL.revokeObjectURL(url);

Download for IE works with FileSaver.js, e.g.

axios({

  responseType: 'blob', // important
}).then((response) => {
  FileSaver.saveAs(new Blob([response.data]));

For me this is not working properly when using blob response type. It only works when i set responseType to arraybuffer. Also when using arraybuffer, it shows downloading after 1 minute or so depending on file size.

Help, this way the pdf is first streamed, then recreated, but without all the images. Can I somehow directly download the created pdf (on the server side, it's all intact, pictures there and everything)? Or how can I get around this?

result.Content.Headers.ContentDisposition.FileName = fileName;

React:
this.apiClient.get(URL, {

Does this save the file to browser memory first, and then initiate the download? The problem is if you are downloading a 10 or 100mb file, the browser will not show any download progress until the entire blob is in the browser memory (you can see the progress in the network tab)
