Json File Tree for Node JS - IoT Shaman

Tree structure representing the contents of a given system drive. Simply pass in a start folder, or a list of files / folders, and this module will return an object that you can use in a user interface to represent your files!

Requirements

In order to use node-json-file-tree you will need the following resource(s):

• npm

Installation

npm install node-json-file-tree --save

Quick Start

The file tree structure can be created in 1 of 2 ways, either by providing a list of files / folders to it's constructor, or using the "seed" factory and providing an address for the root directory.

File Tree Seed (factory method)

Use this factory method to generate a file "seed". A seed will "grow" a file tree for you, first running a recursive directory scan, then converting the results into a file tree. This method is asynchornous and is provided as a Promise.

Methods

get(windows?: boolean = false): Promise<FileTreeSeed>;

Implementation

let ftsf = require('node-json-file-tree').FileTreeSeedFactory
// generate file tree seed from factory
ftsf.get().then(seed => { 
    // "grow" file tree from seed
    let start = __dirname;
    seed.getFileTree(start).then(tree => {
        // ...
    });
});

Manaul (via constructor)

When you already have a list of files / folders, you can manually populate a new instance of FileTree.

let FileTree = require('node-json-file-tree').FileTree;
let tree = new FileTree(['/path/to/file.txt'], ['/path/to/']);
// ...

File Tree Structure

The file tree object has the below definition (in Typescript):

interface FileTree {
    files: string[];
    folders: string[];
    nodes: FileTreeNode;
}
interface FileTreeNode {
    _files_: string[];
    [folder: string]: FileTreeNode;
}

Given the below list of files / folders, the file tree would look like:

• /small/path.txt
• /longer/folder/path2.txt

{
    "small": {
        "_files_": [ "path.txt" ]
    },
    "longer": {
        "folder": {
            "_files_": [ "path2.txt" ]
        },
        "_files_": []
    },
    "_files_": []
}
