GroupDocs.Metadata makes it easy for Node.js via Java developers to add metadata details to JPEG files from within their applications by implementing a few easy steps.
// load the file in an instance of Metadata class
const metadata = new groupdocs.metadata.Metadata('input.jpeg');
// add a property containing the content author
var affected = metadata.addProperties(new groupdocs.metadata.ContainsTagSpecification(
groupdocs.metadata.Tags.getTime().getPrinted()),
new groupdocs.metadata.PropertyValue(new Date()));
// process operation results
console.log('Affected properties: ${affected}');
// save the file with updated metadata
metadata.save('output.jpeg');
