What are the best practices for securing an Express.js application?
To secure an Express.js application, you should implement practices like input validation, using HTTPS, and setting security headers.
Can you explain why using HTTPS is important?
Using HTTPS encrypts the data transmitted between the client and server, protecting sensitive information from eavesdroppers.
What security headers should I set?
You should consider setting headers like Content Security Policy (CSP), X-Content-Type-Options, and X-Frame-Options to enhance security.
How can I prevent SQL injection in my application?
To prevent SQL injection, always use parameterized queries or ORM libraries that handle query sanitization for you.
