How to handle files uploads

Using Cloudinary

The default Implementation is using Cloudinary
The files are sent to the server in the form of a base64 string and then uploaded to Cloudinary
Ensure to create an account on Cloudinary and add the credentials to the .env files

Using Multer

The multer middleware is already configured
It can handle both single and multiple file uploads
use it as follows

import { Router } from Express;
import upload from "./middlewares/multer.middleware";

const router = Router();

router.post("/single-upload", upload.single("image"), (req, res) => {
  // req.body.image: string - will hold the text field, where the file was uploaded on the server
});

router.post("/multiple-upload", upload.multiple("images", 2), (req, res) => {
  // req.body.images: string[] - will hold the text fields, where the files were uploaded on the server
});

There is a cleanup utility function to delete files in utils/delete-files.ts

Multer + Cloudinary

This is an other method that you might find interesting depending on your use case.
It would involve using multer to upload the files to the server and then using cloudinary to upload the files to the cloud.
For this you would have to change the utils/multer.ts file to make use of memory storage instead of disk storage. Then upload the file buffer using the function in utils/cloudinary.ts.
