Fixing req.files Undefined Issue in Express JS for File Uploads node js

Use multer for File Uploads

1. Install multer:

npm install multer

2. Set up the file upload in your Express app:

const express = require('express');
const multer = require('multer');
const app = express();

// Configure multer for file uploads
const upload = multer({ dest: 'uploads/' });

// File upload route
});

});

multer({ dest: 'uploads/' }): This saves uploaded files to the uploads/ directory.

3. HTML Form Example:

form action="/upload" method="POST" enctype="multipart/form-data"
input type="file" name="file" /
button type="submit"Upload File/button
/form
