how to use the dir function from fs-extra in javascript

To use the dir function from the fs-extra package in JavaScript, you need to follow these steps:

1. Install fs-extra package by running the following command in your terminal.

npm install --save fs-extra

2 lines

2. Import the fs-extra package into your project.

index.tsx
const fs = require('fs-extra');
32 chars
2 lines

3. Use the dir function to create a directory at the specified path.

index.tsx
const directoryPath = 'path/to/directory';
fs.ensureDirSync(directoryPath);
76 chars
3 lines

In the above example, fs.ensureDirSync is a synchronous function that creates a directory at the specified path if it doesn't already exist. It also creates any necessary parent directories along the way.

4. Use the dir function to get a list of all files and directories in a directory.

index.tsx
const directoryPath = 'path/to/directory';
const files = fs.readdirSync(directoryPath);
console.log(files);
108 chars
4 lines

In the above example, fs.readdirSync is a synchronous function that returns an array of all files and directories in the specified directory.

5. Use the dir function to check whether a directory exists at a given path.

index.tsx
const directoryPath = 'path/to/directory';
const exists = fs.existsSync(directoryPath);
console.log(exists);
109 chars
4 lines

In the above example, fs.existsSync is a synchronous function that returns true if a directory exists at the specified path, and false otherwise.

That's how you can use the dir function from fs-extra in JavaScript to work with directory paths and the filesystem.
