find the size of a csv file in javascript

To find the size of a csv file in javascript, you can use the XMLHttpRequest object to send a HEAD request to the server and retrieve the Content-Length header of the file. Here's an example code snippet:

index.tsx
function getCsvFileSize(url, callback) {
  var xhr = new XMLHttpRequest();
  xhr.open('HEAD', url);
  xhr.onreadystatechange = function() {
    if (xhr.readyState === XMLHttpRequest.DONE) {
      if (xhr.status === 200) {
        var size = xhr.getResponseHeader('Content-Length');
        callback(parseInt(size));
      } else {
        console.error('getCsvFileSize: request failed with status ' + xhr.status);
        callback(0);
      }
    }
  };
  xhr.send(null);
}

// Usage:
getCsvFileSize('path/to/file.csv', function(size) {
  console.log('The size of file.csv is ' + size + ' bytes.');
});

This function sends a HEAD request to the specified URL and retrieves the Content-Length header from the server's response. It then passes the size (in bytes) to a callback function that you can use to display or further process the result.
