pdf-lib Library for Customizing PDFs in NetSuite

pdf-lib is a JavaScript library that allows dynamic creation and modification of PDFs. In NetSuite, you can leverage pdf-lib within a SuiteScript to customize PDF documents dynamically.

Steps to Use pdf-lib in NetSuite:

1. Include the pdf-lib library: Since NetSuite does not support direct NPM installations, you need to upload pdf-lib as a script file to the NetSuite File Cabinet and reference it in your script.
2. Load the library in your SuiteScript using require.
3. Modify PDF content dynamically.

Key Features of pdf-lib:

• Create PDFs from scratch.
• Modify existing PDFs by adding text, images, and annotations.
• Merge or split PDF pages.

This approach helps in dynamically generating or customizing PDFs in NetSuite without relying on external services.

Sample Script for PDF Modification:

/**
 * @NApiVersion 2.x
 * @NScriptType Suitelet
 */
defined(['N/ui/serverWidget', 'N/file', 'N/log', 'pdf-lib'], function (serverWidget, file, log, PDFLib) {
  function onRequest(context) {
    try {
      // Load an existing PDF from the File Cabinet
      var pdfFile = file.load({ id: '12345' });
      var pdfBytes = pdfFile.getContents();
       
      // Load the document using pdf-lib
      var pdfDoc = PDFLib.PDFDocument.load(pdfBytes);
      var pages = pdfDoc.getPages();
      var firstPage = pages[0];
       
      // Draw text on the first page
      firstPage.drawText('Custom Text', {
        x: 50,
        y: 700,
        size: 12
      });
       
      // Save the modified PDF
      var modifiedPdfBytes = pdfDoc.save();
      var modifiedPdfFile = file.create({
        name: 'modified_document.pdf',
        fileType: file.Type.PDF,
        contents: modifiedPdfBytes,
        folder: 123 // Target folder ID
      });
       
      modifiedPdfFile.save();
      log.debug('Success', 'PDF modified successfully.');
    } catch (e) {
      log.error('Error modifying PDF', e);
    }
  }
  return { onRequest: onRequest };
});
