##directory-tree-promise

Install

  npm install directory-tree-promise

Usage

Use async await while traversing a directory tree.

  const directoryTree = require('directory-tree-promise')
  const tree = await directoryTree('./example')

Output of tree:

{
  "path": "./example",
  "name": "example",
  "children": [
    {
      "path": "example/subfolder",
      "name": "subfolder",
      "children": [
        // excluded
      ],
      "size": 22
    },
    {
      // excluded
    }
  ],
  "size": 34
}

You can also pass an async function as a second parameter to modify the object returned for files

  const directoryTree = require('directory-tree-promise')
  const tree = await directoryTree('./example', async file => {
    file.content = await someFunctionToReadFileData(file.path)
    return file
  })

Object Property Reference

Items are returned with the following properties:

• path (path to item)
• name (name of file including extension)
• extension (extension of object if isFile())
• size (file or folder size in bytes)
• children (array of items)

API Reference

isFile() -> bool

Each object in the tree is extended with a function isFile

  const directoryTree = require('directory-tree-promise')
  const tree = await directoryTree(process.cwd())
  tree.children[0].isFile() // true or false

Note

Device, FIFO and socket files are ignored.
