Example

const path = require("path");

const express = require("express");
const zipper = require("multer-zip").default;
const multer = require("multer");
const upload = multer(/* ... multer opts ... */);
const app = express();

// ... app definitions

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 })
        .then(() => {
            console.log("successfully zipped files");
        })
        .catch(error => {
            console.log(error);
        });

    res.send("zipping...");
});

app.post("/streamable", upload.array("documents", 5), (req, res) => {
    const { files } = req;
    const filenamer = ({ originalname }) => `${new Date().getTime()}_${originalname}`;
    zipper({ files, dest: res, filenamer })
        .then(() => {
            console.log("successfully zipped files");
        })
        .catch(error => {
            console.log(error);
        });
});

const PORT = process.env.PORT || 3000;
app.listen(PORT => console.log(`listening on port ${PORT}`));
