bootstrap-treeview-node

• list directory-tree (recursively) based on directory-tree,
• working nicely with bootstrap-treeview.

Creates an javascript object representing a directory tree.

Install

npm i -S bootstrap-treeview-node

##Usage

var dirTree = require('bootstrap-treeview-node')
var tree = dirTree('/some/path')

And you can also filter by extensions (with Array), or by name patterns (with RegExp):

var dirTree = require('bootstrap-treeview-node')
var filteredTree = dirTree('/some/path', {include: ['.jpg', '.png']})

This will take a directory tree:

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

And return a js object:

{
  "href": "photos",
  "text": "photos",
  "size": 600,
  "nodes": [
    {
      "href": "photos/summer",
      "text": "summer",
      "size": 400,
      "nodes": [
        {
          "href": "photos/summer/june",
          "text": "june",
          "size": 400,
          "nodes": [
            {
              "href": "photos/summer/june/windsurf.jpg",
              "size": 400,
              "text": "windsurf.jpg",
            }
          ]
        }
      ]
    },
    {
      "href": "photos/winter",
      "text": "winter",
      "size": 200,
      "nodes": [
        {
          "href": "photos/winter/january",
          "text": "january",
          "size": 200,
          "nodes": [
            {
              "href": "photos/winter/january/ski.png",
              "text": "ski.png",
              "size": 100,
            },
            {
              "href": "photos/winter/january/snowboard.jpg",
              "text": "snowboard.jpg",
              "size": 100,
            }
          ]
        }
      ]
    }
  ]
}

API

dirTree(path [, options])

• path {String}: is the relative or absolute path to the base directory e.g. '.' for cwd.
• options {Object}: Options object

Options

• href {Function}: overridable function to generate href string from path: href = opts.href(path)s
• root {String}: resolve href path to this root path.
• include {RegExp|Array}: optional, Array tests the file extension, RegExp tests the filename.
• ignore {RegExp|Array}: optional, Array tests the file extension, RegExp tests the filename.

Examples

var tree
tree = dirTree('.', {root: '/', include: ['.jpg', '.png']}) // list only files with .jpg or .png file extensions, resolve href to '/'
tree = dirTree('/home/pi', {include: /^[A-z]/}) // list only files/directories that start with letters
tree = dirTree('../', {ignore: /^\./}) // ignore only files/directories that start with a dot like .git

var relPath = '../node_modules'
tree = dirTree(relPath, {
  href: function (path) { return path.replace(relPath, '') }, // replace relative path and take as new `root href`
  root: '/'
})

Test

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

$ npm test

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