json-directory-async

Get a JSON Object of your directory tree using (promises/async await) to not block other code from running while your directory tree is scanned.

Install

$ npm install json-directory-async
or
$ yarn add json-directory-async

Usage

const { Scanner } = require("json-directory-async");
// or
import { Scanner } from "json-directory-async";

//Javascript

const scan = new Scanner("C://Users");
scan.scan("C://Users").then((json) => {
  console.log(json);
  //or If you want it as a string
  console.log(JSON.parse(json));
});

//Typescript
import type { Documents } from "json-directory-async";

const scan = new Scanner("C://Users");
scan.scan("C://Users").then((json: Documents) => {
  console.log(json);
  //or If you want it as a string
  console.log(JSON.parse(json));
});

You can get folder and file stat information that NodeJS provides

const scan = new Scanner("C://Users", {
  showDepth: true,
  properties: ["mode", "mtime"],
});

You can use a callback to get each file and directory as it is being scanned:

const { Scanner } = require("json-directory-async");

const tree = scan.scan(
  "C://Users",
  {
    showExtension: true,
    showDepth: true,
    showType: false,
    properties: ["dev", "size"],
  },
  (item) => {
    console.log(item);
  }
);
