# 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:

```jsx
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:

```jsx
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.
