How to Handle File Uploads in Node.js Applications?

Handling file uploads in Node.js can be done efficiently using middleware like multer. This library simplifies the process of managing file uploads in your applications.

Here’s a quick guide on how to implement file uploads:

• Step 1: Install multer using npm:

npm install multer

• Step 2: Set up multer in your Express application:

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

• Step 3: Create a route to handle the file upload:

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

• Step 4: Test the file upload functionality using a tool like Postman.

This setup will allow you to efficiently handle file uploads in your Node.js applications.
