  // path match a /^[\da-zA-Z]{5}\.txt$/
  console.log(path);

// return value match a /^[\da-zA-Z]{5}\.tmp$/
mktemp.createFileSync('XXXXX.tmp');

mktemp.createDir('XXXXXXX', function(err, path) {
  if (err) throw err;

  // path match a /^[\da-zA-Z]{7}$/

if support Promise, can use Promise style.

var mktemp = require('mktemp');

mktemp
  .createFile('XXXXX.txt')
  .then(function(path) {
    // path match a /^[\da-zA-Z]{5}\.txt$/
    console.log(path);
  })
  .catch(function(err) {
    console.error(err);
  });

mktemp
  .createDir('XXXXX')
  .then(function(path) {
    // path match a /^[\da-zA-Z]{5}$/
    console.log(path);
  })
  .catch(function(err) {
    console.error(err);
  });

mktemp functions are replace to random string from placeholder "X" in template. see example:

mktemp.createFileSync('XXXXXXX');  // match a /^[\da-zA-Z]{7}$/
mktemp.createFileSync('XXX.tmp');  // match a /^[\da-zA-Z]{3}\.tmp$/
mktemp.createFileSync('XXX-XXX');  // match a /^XXX-[\da-zA-Z]{3}$/
