Javascript – How can I ensure token verification before image uploading?

I have a code so as to upload some images in Node.js. In this code, I’m using the "multer" module for the purpose of image uploading. But I want to ensure that the token of the user is verified before he or she can upload any image to my server. How can I do this?

Here’s my full code:

const express = require("express");
const multer = require("multer");
require("dotenv").config();

const app = express();
const router = express.Router();

app.use(router);

process.on("uncaughtException", (err) => console.error(err));

const storage = multer.createDiskStorage({
    destination: (req, file, cb) => cb(null, "uploads"),
    filename: (req, file, cb) => cb(null, Math.floor(Date.now() / 1000) + file.originalname)
});

const upload = multer({ storage: storage });

router.post("/upload-image", upload.single("image"), async (req, res, next) => {
    if (req.file) {
        res.status(200).json({ status: "OK", file_name: req.file.originalname });
        return next();
    }
    else return res.status(400).json({ status: "Bad Request" });
});

app.listen(process.env.CLOUD_SERVER_PORT, process.env.CLOUD_SERVER_IP_ADDRESS, () => console.log("Cloud server is running..."));

    You can manage token verification in the "filename" section.

    You can add a middleware to handle this authorization/authentication. Plus it is a good practice to separate this process from the actual business logic, and gives you the ability to extend this verification and use it with other routes.
