Protocol – All Files in a Directory

To iterate and process all files in a directory using JavaScript, you can use the Node.js module called fs (file system). This module provides various methods to read, write, and manipulate files and directories.

Example:

In this example, we will demonstrate how to list all files in a directory using the fs.readdir() method.

    
      const fs = require('fs');
      const directoryPath = 'path/to/directory';
      
      fs.readdir(directoryPath, (err, files) => {
        if (err) {
          console.log('Error reading directory:', err);
          return;
        }
        
        files.forEach((file) => {
          console.log(file);
        });
      });

In the above code:

  • fs.readdir() method is used to read the contents of a directory.
  • The directory path is provided as the first argument.
  • If an error occurs while reading the directory, the err parameter will contain the error object.
  • If successful, the files parameter will contain an array of filenames present in the directory.
  • We can iterate over the files array and perform actions on each file.
