const fileName = 'example.txt'; // Replace with your desired file name
const filePath = './path/to/your/file.txt'; // Replace with the path to your local file

// Read the file data
const fileData = fs.readFileSync(filePath);

// Prepare the parameters for the upload
const params = {
  Bucket: bucketName,
  Key: fileName,
  Body: fileData,
};

// Upload the file to Object Storage
cos.upload(params, (err, data) => {
  if (err) {
    console.error('Error uploading file:', err);
  } else {
    console.log('File uploaded successfully:', data);
  }
});

This Node.js symphony commences by importing the essential modules: ‘ibm-cos-sdk’ for interacting with IBM Cloud Object Storage and ‘fs’ for file system operations.
