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);

const url = window.URL.createObjectURL(blob);
const link = document.createElement('a');
link.href = url;
const contentDisposition = response.headers['content-disposition'];
let fileName = 'unknown';
if (contentDisposition) {
    const fileNameMatch = contentDisposition.match(/filename="(.+)"/);
    if (fileNameMatch.length === 2)
        fileName = fileNameMatch[1];
}
link.setAttribute('download', fileName);
document.body.appendChild(link);
link.click();

window.URL.revokeObjectURL(url);

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?

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)

If you'd prefer to have the document open in another tab inline use the following.

The important part is removing the download attribute and adding the type option when creating the Blob.

axios({
  url: 'http://localhost:5000/static/example.pdf',
  method: 'GET',
  responseType: 'blob', // important
}).then((response) => {
  const url = window.URL.createObjectURL(new Blob([response.data], { type: 'application/pdf' }));
  const link = document.createElement('a');
  link.href = url;
  link.target = '_blank'
  link.click();
});

This solution requires the entire downloaded file to fit into the browser's memory. Beyond a certain file size, it will either result in out of memory error, or just crash the browser. Terrible idea.
