walk

What is walk?

The 'walk' npm package is used for traversing directories and handling files within those directories. It provides a simple and efficient way to walk through a directory tree, allowing you to perform operations on files and directories as you encounter them.

What are walk's main functionalities?

Walking a directory

This feature allows you to walk through a directory and handle files and directories as they are encountered. The 'file' event is triggered for each file, and the 'directory' event is triggered for each directory.

const walk = require('walk');

const walker = walk.walk('/path/to/directory', {});

walker.on('file', function (root, fileStats, next) {
  console.log('File: ' + fileStats.name);
  next();
});

walker.on('directory', function (root, dirStats, next) {
  console.log('Directory: ' + dirStats.name);
  next();
});

walker.on('end', function () {
  console.log('All files traversed.');
});

Filtering files

This feature allows you to filter out certain directories from being walked. In this example, the 'node_modules' and '.git' directories are excluded from the traversal.

const walk = require('walk');

const walker = walk.walk('/path/to/directory', {
  filters: ['node_modules', '.git']
});

walker.on('file', function (root, fileStats, next) {
  console.log('File: ' + fileStats.name);
  next();
});

walker.on('end', function () {
  console.log('All files traversed.');
});

Handling errors

This feature allows you to handle errors that occur during the directory traversal. The 'errors' event is triggered when an error is encountered, and you can log or handle the error as needed.

const walk = require('walk');

const walker = walk.walk('/path/to/directory', {});

walker.on('file', function (root, fileStats, next) {
  console.log('File: ' + fileStats.name);
  next();
});

walker.on('errors', function (root, nodeStatsArray, next) {
  nodeStatsArray.forEach(function (n) {
    console.error('Error: ' + n.error.message);
  });
  next();
});

walker.on('end', function () {
  console.log('All files traversed.');
});

Other packages similar to walk

The 'fs-extra' package extends the native Node.js 'fs' module with additional methods and functionality, including methods for walking directories. It provides a more comprehensive set of file system utilities compared to 'walk'.

klaw

The 'klaw' package is a Node.js file system walker that provides a stream-based API for traversing directories. It is similar to 'walk' but offers a more modern and flexible approach with support for streams.

readdirp

The 'readdirp' package is a recursive version of 'fs.readdir' with additional features such as filtering and streaming. It is similar to 'walk' but provides a more powerful and flexible API for reading directories recursively.
