Get a temporary file path you can write to.
The callback resolves with a temporary file path you can write to. The file is automatically cleaned up after the callback is executed. Returns a promise that resolves with the return value of the callback after it is executed and the file is cleaned up.
#### callback
Type: (tempPath: string) => void
A callback that is executed with the temp file path. Can be asynchronous.
#### options
Type: object
You usually won't need either the extension or name option. Specify them only when actually needed.
##### extension
Type: string
File extension.
##### name
Type: string
Filename. Mutually exclusive with the extension option.
##### parentDirectory
Type: string
The name of a directory inside the OS temporary directory to create the temporary file in. The directory is created automatically if it doesn't exist.
By default, the temporary file is created directly inside the OS temporary directory. This option lets you group related temporary files into a subdirectory.
Useful for organizing temporary files by app or task, making cleanup and debugging easier.
`js
import {temporaryFile} from 'tempy';
temporaryFile({parentDirectory: 'my-app'});
//=> '/private/var/folders/3x/jf5977fn79jbglr7rk0tq4d00000gn/T/my-app/4f504b9edb5ba0e89451617bf9f971dd'
`
##### rootDirectory
Type: string
An absolute path to use as the base directory for temporary files, instead of the OS temporary directory.
You usually won't need this option. Prefer the parentDirectory option instead.
Useful for niche use-cases like different filesystem mounts or journaling filesystems. The directory is created automatically if it doesn't exist.
`js
import {temporaryFile} from 'tempy';
temporaryFile({rootDirectory: '/mnt/fast-storage/tmp'});
//=> '/mnt/fast-storage/tmp/4f504b9edb5ba0e89451617bf9f971dd'
`
Get a temporary directory path. The directory is created for you.
The callback resolves with a temporary directory path you can write to. The directory is automatically cleaned up after the callback is executed. Returns a promise that resolves with the return value of the callback after it is executed and the directory is cleaned up.
##### callback
Type: (tempPath: string) => void
A callback that is executed with the temp directory path. Can be asynchronous.
#### options
Type: Object
##### prefix
Type: string
Directory prefix.
Useful for testing by making it easier to identify cache directories that are created.
You usually won't need this option. Specify it only when actually needed.
##### parentDirectory
Type: string
The name of a directory inside the OS temporary directory to create the temporary directory in. The directory is created automatically if it doesn't exist.
By default, the temporary directory is created directly inside the OS temporary directory. This option lets you group related temporary directories into a subdirectory.
`js

temporaryDirectory({parentDirectory: 'my-app'});

Write data to a random temp file.
Write data to a random temp file. The file is automatically cleaned up after the callback is executed. Returns a promise that resolves with the return value of the callback after it is executed and the file is cleaned up.
##### fileContent
Type: string | Buffer | TypedArray | DataView | stream.Readable
Data to write to the temp file.
##### callback
Type: (tempPath: string) => void
A callback that is executed with the temp file path. Can be asynchronous.
##### options
See options.
Synchronously write data to a random temp file.
##### fileContent
Type: string | Buffer | TypedArray | DataView
Data to write to the temp file.
##### options
See options.
Get the root temporary directory path. For example: /private/var/folders/3x/jf5977fn79jbglr7rk0tq4d00000gn/T`
