Useful if you need to view the Base64 PDF in your app before the user decides to download it.
In modern web development, downloading files directly from a browser without a dedicated server-side file URL is a common requirement. In Vue.js , the "vue download base64 pdf" pattern typically involves receiving a Base64-encoded string from an API and triggering a client-side download. Set the href and download attributes downloadLink
const downloadBase64PDF = (base64String, fileName = 'document.pdf') => { // 1. Ensure the string has the correct Data URL prefix const linkSource = `data:application/pdf;base64,${base64String}`; // 2. Create a temporary anchor element const downloadLink = document.createElement("a"); // 3. Set the href and download attributes downloadLink.href = linkSource; downloadLink.download = fileName; // 4. Trigger the download downloadLink.click(); }; Use code with caution. 2. The Blob Strategy (Recommended for Large Files)
APIs sometimes return the Base64 string with the data:application/pdf;base64, prefix already attached, and sometimes they don't. Always check if the string starts with JVB (the Base64 signature for %PDF ) to decide whether to append the prefix manually.
