2 lines

Next, you can call the readdir function to read the contents of a directory:

index.ts
fs.readdir('/path/to/directory', (err, files) => {
  if (err) {
    console.error(err);
    return;
  }

  console.log(files);
  // handle files here
});

10 lines

The first argument to readdir is the path to the directory you want to read. The second argument is a callback function that is called when the read operation is complete. In the callback function, you can handle the returned files array or handle any errors that occurred during the read operation.

Note that the fs-extra library is an extension of the built-in fs module in Node.js, providing additional functionality and safety features.
