PDF generator available?

Ask us anything

I managed to create my own pdf receipt using pdf-lib and my top co-worker chat-GPT. A few things to know;

The instance name is PDFLib.
Ask chat-GPT to do write small sections at a time.
If your wanting to print straight away on a button press this is how you can do it.

createReceipt().then((pdfBytes) => { 
  const blob = new Blob([pdfBytes], { type: 'application/pdf' });
  // Create a Blob URL for the Blob
  const pdfBlobUrl = URL.createObjectURL(blob);
  // Create a hidden iframe element
  var iframe = document.createElement('iframe');
  iframe.style.display = 'none';
  iframe.src = pdfBlobUrl;
  // Append the iframe to the document body
  document.body.appendChild(iframe);
  // Wait for the PDF to load in the iframe
  iframe.onload = function() {
    // Call print on the iframe's content window
    iframe.contentWindow.print();
    // Optionally, remove the iframe after printing
    setTimeout(function() {
       document.body.removeChild(iframe);
     }, 2000);
  };
});

Here’s PDF-LIB’s documentation https://pdf-lib.js.org/

Hope this helps,
Good Luck!
