File Uploads

Handle file uploads using middleware like multer.

a. Install Multer

npm install multer

b. Configure Multer

In app.js:

const multer = require('multer');
const upload = multer({ dest: 'uploads/' });

app.post('/upload', upload.single('file'), (req, res) => {
  res.send('File uploaded successfully');
});

Here, dest specifies the directory where files will be stored, and upload.single('file') handles single file uploads.
