How do you get a list of the names of all files present in a directory in Node.js?

In Node.js, you can use the fs (file system) module to get a list of file names in a directory. Here's an example using the fs.readdir function:

const fs = require('fs');

const directoryPath = '/path/to/your/directory';

// Read the contents of the directory
fs.readdir(directoryPath, (err, files) => {
  if (err) {
    console.error('Error reading directory:', err);
    return;
  }

  // Log the list of file names
  console.log('Files in the directory:');
  files.forEach(file => {
    console.log(file);
  });
});

Replace '/path/to/your/directory' with the actual path of the directory you want to list files from.

In this example:

• fs.readdir is used to read the contents of the specified directory.
• The callback function receives an array of file names (files) or an error (err).
• If there is an error, it's logged to the console. Otherwise, it logs each file name in the directory.

Note that the file names returned by readdir include both files and directories. If you want to filter only files, you can use the fs.stat method to check the type of each entry.

Here's an updated example that filters only files:

const fs = require('fs');
const path = require('path');

const directoryPath = '/path/to/your/directory';

fs.readdir(directoryPath, (err, files) => {
  if (err) {
    console.error('Error reading directory:', err);
    return;
  }

  // Filter only files
  const fileNames = files.filter(file => {
    const filePath = path.join(directoryPath, file);
    return fs.statSync(filePath).isFile();
  });

  console.log('Files in the directory:');
  fileNames.forEach(fileName => {
    console.log(fileName);
  });
});

In this updated example, fs.statSync(filePath).isFile() is used to check if each entry is a file. The path.join method is used to construct the full path to each file.
