function promises.mkdtemp
Usage in Deno
```typescript import { promises } from "node:node__fs.d.ts"; ```
mkdtemp(prefix: string,options?: ,): Promise<string>
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.
```js
import { mkdtemp } from 'node:fs/promises';
import { join } from 'node:path';
import { tmpdir } from 'node:os';
try {
await mkdtemp(join(tmpdir(), 'foo-'));
} catch (err) {
console.error(err);
}
```
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`, the `prefix` must end with a trailing
platform-specific path separator
(`import { sep } from 'node:path'`).
Promise<string>
Fulfills with a string containing the file system path of the newly created temporary directory.
mkdtemp(prefix: string,options: BufferEncodingOption,): Promise<Buffer>
Asynchronously creates a unique temporary directory.
Generates six random characters to be appended behind a required `prefix` to create a unique temporary directory.
options: BufferEncodingOption
The encoding (or an object specifying the encoding), used as the encoding of the result. If not provided, `'utf8'` is used.
Promise<Buffer>
mkdtemp(prefix: string,options?: ,): Promise<string | Buffer>
Asynchronously creates a unique temporary directory.
