Open the Initial/image-storage directory. Inside the directory, you will find a package.json file and an app.js file. The app.js file is where you will write the code, and package.json lists the dependencies for the image storage server. The upload service is dependent on express, connect-multiparty, path, and fs. Run the npm install command inside Initial/image-storage to install the dependencies locally.

The following is the code to import the modules:

var express = require("express");
var app = express();
var fs = require("fs");
