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

  if (err) throw err;
 
  // path match a /^[\da-zA-Z]{7}$/ 
  console.log(path);
});

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}$/
