Function __promisify__

  • __promisify__(file: PathOrFileDescriptor, data: string | Uint8Array, options?: WriteFileOptions): Promise<void>

  • Asynchronously append data to a file, creating the file if it does not exist.

    Parameters

    • file: PathOrFileDescriptor

      A path to a file. If a URL is provided, it must use the file: protocol. URL support is experimental. If a file descriptor is provided, the underlying file will not be closed automatically.

    • data: string | Uint8Array

      The data to write. If something other than a Buffer or Uint8Array is provided, the value is coerced to a string.

    • Optional options: WriteFileOptions

      Either the encoding for the file, or an object optionally specifying the encoding, file mode, and flag. If encoding is not supplied, the default of 'utf8' is used. If mode is not supplied, the default of 0o666 is used. If mode is a string, it is parsed as an octal integer. If flag is not supplied, the default of 'a' is used.

    Returns Promise<void>
