## API
### temporaryFile(options?)
Get a temporary file path you can write to.
### temporaryFileTask(callback, options?)
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.
### temporaryDirectory(options?)
Get a temporary directory path. The directory is created for you.
### temporaryDirectoryTask(callback, options?)
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.*
### temporaryWrite(fileContent, options?)
Write data to a random temp file.
### temporaryWriteTask(fileContent, callback, options?)
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](#options).
### temporaryWriteSync(fileContent, 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](#options).
### rootTemporaryDirectory
Get the root temporary directory path. For example: `/private/var/folders/3x/jf5977fn79jbglr7rk0tq4d00000gn/T`
