import axios from 'axios';

const downloadFile = () => {
  axios({
    url: 'http://your-api-url/download', // Replace with your actual API URL
    method: 'GET',
    responseType: 'blob', // Important: Set responseType to 'blob' for binary data
  })
    .then((response) => {
      // Create a blob URL for the response data
      const url = window.URL.createObjectURL(new Blob([response.data]));
      
      // Create a temporary <a> element to trigger the download
      const link = document.createElement('a');
      link.href = url;
      link.setAttribute('download', 'filename.ext'); // Set the desired filename
      document.body.appendChild(link);
      link.click();

      // Clean up the URL object
      window.URL.revokeObjectURL(url);
    })
    .catch((error) => {
      console.error('Error downloading file:', error);
    });
};

const FileDownloadButton = () => {
  return (
    <button onClick={downloadFile}>Download File</button>
