fsxt

Improved fork of fs-extra with extra [sic] features! fsxt provides support for Node 16 and above. Node 17 is required for better feature support.

Installation

npm install fsxt

pnpm install fsxt

yarn add fsxt
Copy

Or install with your preferred package manager (yarn, pnpm, ...)

Usage

fsxt is a mostly drop-in replacement for the node.js core fs module. All methods in fs can be used in their standard forms in fsxt, with some improvements.

You don't ever need to include the original fs module again:

const fs = require('fs'); // this is no longer necessary
Copy

you can now do this:

const fs = require('fsxt');
Copy

or if you prefer to make it clear that you're using fsxt and not fs, you may want to name your fs variable fsxt like so:

const fsxt = require('fsxt');
Copy

you can also keep both, but it's redundant:

const fs = require('fs');
const fsxt = require('fsxt');
Copy

Breaking changes from node:fs

The callback-based implementation of fs.exists now uses a propper error-first callback system like mz/fs.

Improvements on node:fs

All the improvements from mz/fs are included, which also includes improvements from graceful-fs.

Most methods are async by default, returning a Promise that resolves to the method's result, or rejects if the operation fails.

Sync methods on the other hand will throw if an error occurs, and directly return the resulting value to the caller if the operation succeeds.

You can also use the methods in the legacy node.js form, passing a callback as the last parameter, as a function that takes (error, result) parameters.

Example use:

const fs = require('fsxt');
// or
// import * as fs from 'fsxt';

// Async with promises:
fs.copy('/tmp/myfile', '/tmp/mynewfile')
  .then(() => console.log('success!'))
  .catch(err => console.error(err));

// Async with callbacks:
fs.copy('/tmp/myfile', '/tmp/mynewfile', err => {
  if (err) return console.error(err);
  console.log('success!');
});

// Sync:
try {
  fs.copySync('/tmp/myfile', '/tmp/mynewfile');
  console.log('success!');
} catch (err) {
  console.error(err);
}

// Async/Await:
async function copyFiles() {
  try {
    await fs.copy('/tmp/myfile', '/tmp/mynewfile');
    console.log('success!');
  } catch (err) {
    console.error(err);
  }
}

copyFiles();
Copy

Hacking on fsxt

Do you want to hack on fsxt? Well, you probably shouldn't. Still, you can go ahead and send a PR.

Please, no changes to anything in the lib folder; the contents of that folder are taken entirely verbatim from fs-extra, so they should be submitted upstream.

Running the Test Suite

fsxt contains like at least 4 tests that pass.

• npm run lint: runs eslint
• npm run test: runs the tests
• npm run test-no-fse: runs the tests, except for fs-extra tests

Windows

If you run the tests on the Windows and receive a lot of symbolic link EPERM permission errors, it's because on Windows you need elevated privilege to create symbolic links. You can either run the tests as Administrator or run npm run test-no-fse to test only fsxt-exclusive methods, which doesn't include symbolic links
