How can I secure my Express.js application?
To secure your Express.js application, you can implement several strategies such as using HTTPS, validating user input, and setting security headers.
What are some common security vulnerabilities in Express.js?
Common vulnerabilities include Cross-Site Scripting (XSS), SQL Injection, and Cross-Site Request Forgery (CSRF). It's important to use libraries like Helmet to mitigate these risks.
How do I implement HTTPS in my Express.js app?
You can implement HTTPS by using the 'https' module in Node.js and providing an SSL certificate. Here's a basic example:
const https = require('https');
const fs = require('fs');
const options = {
key: fs.readFileSync('path/to/your/private.key'),
cert: fs.readFileSync('path/to/your/certificate.crt')
};
https.createServer(options, app).listen(443);
