Function mkdtemp

Creates a unique temporary directory. A unique directory name is generated by appending six random characters to the end of the provided prefix. Due to platform inconsistencies, avoid trailing X characters in prefix. Some platforms, notably the BSDs, can return more than six random characters, and replace trailing X characters in prefix with random characters.

The optional options argument can be a string specifying an encoding, or an object with an encoding property specifying the character encoding to use.

import { mkdtemp } from 'fs/promises';

try {
  await mkdtemp(path.join(os.tmpdir(), 'foo-'));
} catch (err) {
  console.error(err);
}
Copy

The fsPromises.mkdtemp() method will append the six randomly selected characters directly to the prefix string. For instance, given a directory/tmp, if the intention is to create a temporary directory within/tmp, theprefix must end with a trailing platform-specific path separator (import { sep } from 'node:path').
