Create a temporary 'a' element to trigger the download const linkElement = document.createElement('a'); linkElement.setAttribute('href', dataUri); linkElement.setAttribute('download', fileName); // 4. Append to body, click, and then remove it document.body.appendChild(linkElement); linkElement.click(); linkElement.remove(); } Use code with caution.
