For handling file uploads, we are going to use a module named multer (https://www.npmjs.com/package/multer), and for managing file uploads to Cloudinary, we are going to use an npm named Cloudinary (https://www.npmjs.com/package/cloudinary). We are also going to use an npm named request (https://www.npmjs.com/package/request) for making HTTP calls from Node.js. Run the following command from the root of the application:

$ npm install --save cloudinary multer request

Or, you can run the following command instead:

$ yarn add cloudinary multer request
