Supercharged Document Signing

GroupDocs.Signature for Node.js via Java 23.12 lets developers integrate a seamless document signing experience into their applications. It enables them to sign critical documents directly within their solutions. The following code example illustrates the feature usage.



const groupdocs = require('@groupdocs/groupdocs.signature')

function signWithBarcode(filePath, outputPath) {
  const signature = new groupdocs.Signature(filePath);

  // Create barcode option with predefined barcode text
  const options = new groupdocs.BarcodeSignOptions('JohnSmith');
  // Setup barcode encoding type
  options.setEncodeType(groupdocs.BarcodeTypes.Code128);
  // Set signature position
  options.setLeft(100);
  options.setTop(100);
  options.setWidth(200);
  options.setHeight(50);
  
  // Sign document to file
  signature.sign(outputFilePath, options);
}

module.exports = signWithBarcode

Document Signature Verification

Beef up the security of your applications by offering signature verification capabilities with this version of the Node.js document signing API. Users can effortlessly verify and confirm the authenticity of signed documents, as highlighted in this code sample.



function verifyBarcode(filePath) { 
  // Initialize Signature instance
  const signature = new groupdocs.Signature(filePath);

  // Initialize BarcodeVerifyOptions
  const options = new groupdocs.BarcodeVerifyOptions();
  options.setAllPages(true); // This value is set by default
  options.setText('John');
  options.setMatchType(groupdocs.TextMatchType.Contains);

  // Verify document signatures
  const result = signature.verify(options);

  if (result.isValid()) {
    console.log('\nDocument was verified successfully!');
  } else {
    console.log('\nDocument failed the verification process.');
  }
}

module.exports = verifyBarcode

With GroupDocs.Signature for Node.js via Java 23.12, users can work with a tool that allows them to locate and validate signatures embedded within their documents. This sample code illustrates signature search in Node.js.



function searchForBarcode(filePath) {
  const signature = new groupdocs.Signature(filePath);
  const options = new groupdocs.BarcodeSearchOptions();
  options.setAllPages(true); // this value is set by default

  // Search for signatures in the document
  const signatures = signature.search(groupdocs.BarcodeSignature.class, options).toArray();
  console.log('\nSource document contains the following signatures.');

  for (const barcodeSignature of signatures) {
    console.log(`Barcode signature found at page ${barcodeSignature.getPageNumber()} with type ${barcodeSignature.getEncodeType()} and text ${barcodeSignature.getText()}`);
  }
}

module.exports = searchForBarcode

Document Information Retrieval

Retrieve extensive file information in your document signing solutions, such as metadata, formatting, and page count, for improved processing. Check out this example code to learn how to use this feature.



function getDocumentInfo(filePath) {

  const signature = new groupdocs.Signature(filePath);

  const documentInfo = signature.getDocumentInfo();

  console.log(`Document properties ${path.basename(filePath)}`);
  console.log(` - format : ${documentInfo.getFileType().getFileFormat()}`);
  console.log(` - extension : ${documentInfo.getFileType().getExtension()}`);
  console.log(` - size : ${documentInfo.getSize()}`);
  console.log(` - page count : ${documentInfo.getPageCount()}`);
  console.log(` - Form Fields count : ${documentInfo.getFormFields().size()}`);
  console.log(` - Text signatures count : ${documentInfo.getTextSignatures().size()}`);
  console.log(` - Image signatures count : ${documentInfo.getImageSignatures().size()}`);
  console.log(` - Digital signatures count : ${documentInfo.getDigitalSignatures().size()}`);
  console.log(` - Barcode signatures count : ${documentInfo.getBarcodeSignatures().size()}`);
  console.log(` - QrCode signatures count : ${documentInfo.getQrCodeSignatures().size()}`);
  console.log(` - FormField signatures count : ${documentInfo.getFormFieldSignatures().size()}`);

  for (const pageInfo of documentInfo.getPages().toArray()) {
    console.log(` - page-${pageInfo.getPageNumber()} Width ${pageInfo.getWidth()}, Height ${pageInfo.getHeight()}`);
  }
}

module.exports = getDocumentInfo
