My Business Requirements is that downloads do not trigger a new tab to open.

When I download a signed download link, it will open a new tab and then quickly close it before downloading. I find it strange. Is there any way to trigger the download in the current tab?

I have to use the following code for substitution:

const a = document.createElement('a');
    a.href = res?.DomainObj;
    a.download = fileName;
    a.click();

Is there any configuration that can be operated?

I have the exact same doubt. I also replaced FileSaver.js with direct a[download] that does not trigger a new tab:

   const downloadLink = document.createElement('a');

    downloadLink.href = downloadUrl;
    document.body.appendChild(downloadLink);
    downloadLink.click();
    document.body.removeChild(downloadLink);

Looking at the source code it, when CORS is not enabled and adds a.target = '_blank' https://github.com/eligrey/FileSaver.js/blob/master/src/FileSaver.js#L99 is there a specific reason for it?

If the download fails and you aren't using a.target = '_blank', then your webpage will be replaced by the error page, if you do it in a new tab, then the new tab is the one with the error page.
