dir-to-json

Asynchronously convert directory tree structure into a JavaScript object.

Getting Started

Install

Yarn:

yarn add dir-to-json

NPM:

npm install dir-to-json --save

Usage

import dirToJson from "dir-to-json";

dirToJson("./path/to/my/dir", { sortType: true })
	.then(function (dirTree) {
		console.log(dirTree);
	})
	.catch(function (err) {
		throw err;
	});

Callback syntax

The callback syntax has been split into another module in version 1.0.0. If you would still like to use it, just change your import to dir-to-json/callback:

import dirToJson from "dir-to-json/callback";

dirToJson("./path/to/my/dir", function (err, dirTree) {
	if (err) {
		throw err;
	} else {
		console.log(dirTree);
	}
});

Requirements

• NodeJS version 14 or higher

Since Version 1.0.0 of dir-to-json, the lowest supported version of NodeJS is 14. If you are using an older version of Node, try installing dir-to-json@0.0.3
