Mongez FS is a sync file system for Nodejs that aims to make working with file system easier and more efficient.

Features

- The package covers all file system operations in simple usage.
- It is sync, so you can use it in your code without callbacks or promises.
- There is also async version of all methods.
- Works with files or directories.

Installation

``bash
npm install @mongez/fs
`

Using Yarn

`bash
yarn add @mongez/fs
`

Using pnpm

`bash
pnpm add @mongez/fs
`

Usage

All methods are sync, so you can use them in your code without callbacks or promises.

`ts
import { fileExists } from '@mongez/fs';
`

Copy file or directory

Copy a file or directory to another location.

`ts
import { copyPath, copyDirectory, copyFile } from '@mongez/fs';
