File Copying

This feature allows for copying files and directories from one location to another. The code sample demonstrates how to use the async/await syntax to copy files.

import fs from 'fs-extra';

async function copyFiles() {
  try {
    await fs.copy('/path/to/source', '/path/to/dest');
    console.log('Files copied successfully!');
  } catch (err) {
    console.error(err);
  }
}

Reading and Writing JSON Files

This feature simplifies the process of reading and writing JSON files. The code sample shows how to read a JSON file, modify its content, and then write it back.

import fs from 'fs-extra';

async function readAndWriteJson() {
  try {
    const data = await fs.readJson('/path/to/some.json');
    console.log(data);
    data.newProp = 'newValue';
    await fs.writeJson('/path/to/some.json', data);
    console.log('JSON file updated successfully!');
  } catch (err) {
    console.error(err);
  }
}

Ensuring a Directory Exists

This feature checks if a directory exists, and if it does not, creates it. The code sample demonstrates how to ensure a directory exists.

import fs from 'fs-extra';

async function ensureDir() {
  try {
    await fs.ensureDir('/path/to/dir');
    console.log('Directory exists or was created successfully!');
  } catch (err) {
    console.error(err);
  }
}
