fs-extra

Copying files and directories

This feature allows you to copy files and directories from one location to another. The method returns a promise that resolves when the operation is complete.

const fs = require('fs-extra');

fs.copy('/path/to/source', '/path/to/dest')
  .then(() => console.log('Copy successful!'))
  .catch(err => console.error(err));

Moving files and directories

This feature enables you to move files and directories to a new location. Like copy, it returns a promise and provides a simple API for a task that would otherwise require multiple steps.

const fs = require('fs-extra');

fs.move('/path/to/source', '/path/to/dest')
  .then(() => console.log('Move successful!'))
  .catch(err => console.error(err));

Removing files and directories

This feature is used to delete files and directories. It is a safer and more powerful alternative to the standard 'fs.unlink' and 'fs.rmdir' methods, as it can remove non-empty directories.

const fs = require('fs-extra');

fs.remove('/path/to/dir')
  .then(() => console.log('Removal successful!'))
  .catch(err => console.error(err));

Reading and writing JSON files

This feature simplifies the process of reading and writing JSON files. It automatically handles stringifying objects when writing and parsing JSON data when reading.

const fs = require('fs-extra');

const myData = { name: 'fs-extra' };
fs.writeJson('/path/to/file.json', myData)
  .then(() => console.log('Write successful!'))
  .catch(err => console.error(err));

Ensuring a file or directory exists

This feature checks if a file or directory exists, and if it does not, it is created. This is useful for making sure that a given file or directory is present before performing operations on it.

const fs = require('fs-extra');

fs.ensureFile('/path/to/file.txt')
  .then(() => console.log('File exists!'))
  .catch(err => console.error(err));
