How can I secure my Express.js application using middleware?

How can I secure my Express.js application using middleware?

You can use middleware like helmet, cors, and express-rate-limit to enhance security in your Express.js app.

What does the helmet middleware do?

Helmet helps secure your Express apps by setting various HTTP headers, protecting against common vulnerabilities.

Can you give me an example of using express-rate-limit?

Sure! You can set it up like this: const rateLimit = require('express-rate-limit'); const limiter = rateLimit({ windowMs: 15 * 60 * 1000, max: 100 }); app.use(limiter); This limits each IP to 100 requests per 15 minutes.

Are there any other security practices I should follow?

Yes, always validate user input, use HTTPS, and keep your dependencies updated to minimize security risks.
