app.post("/", upload.array("documents", 5), (req, res) => {
	const { files } = req;
	const dest = path.join(__dirname, "uploads");
	const zipname = `files_${Math.random()}.zip`;
	const filenamer = ({ originalname }) => `${new Date().getTime()}_${originalname}`;
	zipper({ files, dest, zipname, filenamer })
