A CLOUD CONFIG FILE IS CREATED 

CloudConfig.js

const cloudinary = require("cloudinary").v2;

const { CloudinaryStorage } = require("multer-storage-cloudinary");

cloudinary.config({

  cloud_name: process.env.CLOUD_NAME,

  api_key: process.env.CLOUD_API_KEY,

  api_secret: process.env.CLOUD_API_SECRET,

});

const storage = new CloudinaryStorage({

  cloudinary: cloudinary,

  params: {

    folder: "wanderlust_DEV",

    allowedFormat: ["png", "jpeg", "jpg"],

  },

});

module.exports = {

  cloudinary,

  storage,

};

in APP.JS

const multer = require("multer");

const { storage } = require("../CloudConfig.js");

const upload = multer({ storage });

router

  .get(wrapAsync(listingController.index))

  // .post(

  //   isLoggedIn,

  //   ValidateListing,

  //   wrapAsync(listingController.postNewListing)

  // );

  .post(upload.single("listing[image]"), (req, res) => {
