NodeJs — Security Best Practices

Security is crucial for production applications. Best practices include validating inputs, using HTTPS, protecting against SQL injection and XSS, and securely storing secrets.

// Example: helmet for security headers
npm install helmet

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

app.use(helmet());

app.get('/', (req, res) => res.send('Secure server'));

app.listen(3000);
