Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including directory-tree with all npm packages installed. Try it out:

var directoryTree = require("directory-tree")

directory-tree v2.2.4

Convert a directory tree to a JS object.

Build Status

directory-tree

Creates a JavaScript object representing a directory tree.

Install

$ npm install directory-tree

Usage

const dirTree = require("directory-tree");
const tree = dirTree("/some/path");

And you can also filter by an extensions regex: This is useful for including only certain types of files.

const dirTree = require("directory-tree");
const filteredTree = dirTree("/some/path", { extensions: /\.txt/ });

Example for filtering multiple extensions with Regex.

const dirTree = require("directory-tree");
const filteredTree = dirTree("/some/path", {
  extensions: /\.(md|js|html|java|py|rb)$/
});

You can also exclude paths from the tree using a regex:

const dirTree = require("directory-tree");
const filteredTree = dirTree("/some/path", { exclude: /some_path_to_exclude/ });

You can also specify which additional attributes you would like to be included about each file/directory:

const dirTree = require('directory-tree');
const filteredTree = dirTree('/some/path', {attributes:['mode', 'mtime']});

The default attributes are [name, size, extension, path] for Files and [name, size, path] for Directories

A callback function can be executed with each file that matches the extensions provided:

const PATH = require('path');
const dirTree = require('directory-tree');

const tree = dirTree('./test/test_data', {extensions:/\.txt$/}, (item, PATH, stats) => {
    console.log(item);
});

The callback function takes the directory item (has path, name, size, and extension) and an instance of node path and an instance of node FS.stats.

You can also pass a callback function for directories:

const PATH = require('path');
const dirTree = require('directory-tree');

const tree = dirTree('./test/test_data', {extensions:/\.txt$/}, null, (item, PATH, stats) => {
    console.log(item);
});

Options

exclude : RegExp|RegExp[] - A RegExp or an array of RegExp to test for exlusion of directories.

extensions : RegExp - A RegExp to test for exclusion of files with the matching extension.

attributes : string[] - Array of FS.stats attributes.

normalizePath : Boolean - If true, windows style paths will be normalized to unix style pathes (/ instead of \).

Result

Given a directory structured like this:

photos
├── summer
│   └── june
│       └── windsurf.jpg
└── winter
    └── january
        ├── ski.png
        └── snowboard.jpg

directory-tree will return this JS object:

{
  "path": "photos",
  "name": "photos",
  "size": 600,
  "type": "directory",
  "children": [
    {
      "path": "photos/summer",
      "name": "summer",
      "size": 400,
      "type": "directory",
      "children": [
        {
          "path": "photos/summer/june",
          "name": "june",
          "size": 400,
          "type": "directory",
          "children": [
            {
              "path": "photos/summer/june/windsurf.jpg",
              "name": "windsurf.jpg",
              "size": 400,
              "type": "file",
              "extension": ".jpg"
            }
          ]
        }
      ]
    },
    {
      "path": "photos/winter",
      "name": "winter",
      "size": 200,
      "type": "directory",
      "children": [
        {
          "path": "photos/winter/january",
          "name": "january",
          "size": 200,
          "type": "directory",
          "children": [
            {
              "path": "photos/winter/january/ski.png",
              "name": "ski.png",
              "size": 100,
              "type": "file",
              "extension": ".png"
            },
            {
              "path": "photos/winter/january/snowboard.jpg",
              "name": "snowboard.jpg",
              "size": 100,
              "type": "file",
              "extension": ".jpg"
            }
          ]
        }
      ]
    }
  ]
}

Note

Device, FIFO and socket files are ignored.

Files to which the user does not have permissions are included in the directory tree, however, directories to which the user does not have permissions, along with all of its contained files, are completely ignored.

Dev

To run tests go the package root in your CLI and run,

$ npm test

Make sure you have the dev dependencies installed (e.g. npm install .)
