mktmpdir v0.1.1

mktmpdir

mktmpdir creates a temporary directory, ported from Ruby's Dir.mktmpdir.

var mktmpdir = require('mktmpdir');

mktmpdir(function(err, dir, done) {
  if (err) throw err;
  // use the directory...
  fs.writeFile(dir + '/foo', 'hello, World', done);
}, function(err, dir) {
  // after the directory is removed.
});

Installation

$ npm install mktmpdir

Usage

mktmpdir(prefixSuffix, tmpdir, callback, onend)

The prefix and suffix of the name of the directory is specified by prefixSuffix. The directory is created under tmpdir or os.tmpdir() with 0700 permission.

Examples

mktmpdir(function(err, dir) {
  // dir is ".../d..."
});

mktmpdir('foo', function(err, dir) {
  // dir is ".../foo..."
});

mktmpdir(['foo', 'bar'], function(err, dir) {
  // dir is ".../foo...bar"
});

mktmpdir(null, '/var/tmp', function(err, dir) {
  // dir is "/var/tmp/d..."
});

// If a callback is invoked, the path of the directory and its contents are removed.
mktmpdir(function(err, dir, done) {
  if (err) throw err;
  fs.open(dir + '/foo', 'w', function(err, fd) {
    done(err);
  });
}, function(err) {
  // the directory has been removed.
});

// If a callback is not invoked, `mktmpdir` doesn't remove the directory.
mktmpdir(function(err, dir) {
  if (err) throw err;
  fs.open(dir + '/foo', 'w', function(err, fd) {
    // remove the directory.
    exec('rm -rf ' + dir);
  });
});
