module.exports = { saveGifMetadata }; This is a basic example to demonstrate the feature. You'll need to modify and extend it to fit your specific requirements. Additionally, ensure you handle errors, implement security measures (e.g., validate user input), and optimize performance.

Here's a high-level example using Node.js, Express.js, and AWS S3:
