fs.extra

fs.extra

Adds copy, copyRecursive, mkdirp, move, walk, and rmrf to Node.JS' fs.

Install with npm install -S fs.extra

// this will have all of the normal fs methods
var fs = require('fs.extra');

fs.copy

Creates an fs.readStream and fs.writeStream and uses util.pump to efficiently copy.

fs.copy('foo.txt', 'bar.txt', function (err) {
  if (err) {
    throw err;
  }

  console.log("Copied 'foo.txt' to 'bar.txt');
});

fs.copyRecursive

Basically a local rsync, uses fs.copy to recursively copy files and folders (with correct permissions).

fs.copyRecursive('./foo', './bar', function (err) {
  if (err) {
    throw err;
  }

  console.log("Copied './foo' to './bar');
});

fs.mkdirp

Included from https://github.com/substack/node-mkdirp

// fs.mkdirp(path, mode=(0777 & (~process.umask())), cb);

fs.mkdirp('/tmp/foo/bar/baz', function (err) {
  if (err) {
    console.error(err);
  } else {
    console.log('pow!')
  }
});

fs.mkdirpSync

Included from https://github.com/substack/node-mkdirp

// fs.mkdirpSync(path, mode=(0777 & (~process.umask())));

try {
  fs.mkdirpSync('/tmp/foo/bar/baz');
} catch(e) {
  throw e;
}

fs.move

Attempts fs.rename, then tries fs.copy + fs.unlink before failing.

fs.move('foo.txt', 'bar.txt', function (err) {
  if (err) {
    throw err;
  }

  console.log("Moved 'foo.txt' to 'bar.txt');
});

fs.rmrf

Included from https://github.com/jprichardson/node-fs-extra

Recursively deletes a directory (like rm -rf)

// fs.rmrf(dir, callback);

fs.rmrf('/choose/me/carefully/', function (err) {
  if (err) {
    console.error(err);
  }
});

fs.rmrfSync

Included from https://github.com/jprichardson/node-fs-extra

Recursively deletes a directory (like rm -rf)

// fs.rmrfSync(dir);

fs.rmrfSync('/choose/me/carefully/');

fs.walk

See https://github.com/coolaj86/node-walk

var walker = fs.walk(dir)
  ;

// file, files, directory, directories
walker.on("file", function (root, stat, next) {
  var filepath = path.join(root, stat.name)
    ;

  console.log(filepath);
});

Aliases

For the sake of consistency you can call the recursive functions with their names as such

fs.rmRecursive <- fs.rmrf
fs.rmRecursiveSync <- fs.rmrfSync
fs.mkdirRecursive <- fs.mkdirp
fs.mkdirRecursiveSync <- fs.mkdirpSync
