Directory Structure JSON

This module exposes functions with which you can:

• Get a JSON tree/structure of a folder (including subdirectories and files), note that you have specify the filesystem to use yourself. You can get JSON tree for a directory with n levels of children.

• Traverse a structure, giving callbacks to execute when a file or folder is found.

• It gives you all the details of the file and folder including date created, size in actual units, file extension and local path.

• You can use to it get only size of file you are uploading: Size Units: ['bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB']

Installation

npm install --save json-dir-tree

Get directory structure

var JsonDirTree = require('json-dir-tree');
var basepath = 'path/to/some/folder';
var fs = require('fs'); // you can select any filesystem as long as it implements the same functions that native fs uses.

JsonDirTree.getStructure(fs, basepath, function (err, structure, total) {
    if (err) console.log(err);

    console.log('there are a total of: ', total.folders, ' folders and ', total.files, ' files');
    console.log('the structure looks like: ', JSON.stringify(structure, null, 4));
});

Traverse structure

The structure retrieved from the example above can be traversed.

var JsonDirTree = require('json-dir-tree');
var basepath = 'path/to/some/folder'; // this will be prepended to the paths found in the structure

JsonDirTree.traverseTree(structure, basepath,
function (folder, path) {
    console.log('folder found: ', folder.name, 'at path: ', path);
},
function (file, path) {
    console.log('file found: ', file.name, 'at path: ', path);
});

Get file size

var JsonDirTree = require('json-dir-tree');
var basepath = 'path/to/some/file'; // this will be prepended to the paths found in the structure
var fileSize = JsonDirTree.getFileSize(basepath);
