How do you ensure data security when working with databases like MongoDB and PostgreSQL?
Data security is paramount. When working with databases like MongoDB or PostgreSQL, I follow best practices, such as using environment variables for sensitive data, setting up proper user roles, and implementing necessary security measures to protect against potential vulnerabilities.
Can you integrate third-party APIs into the web application you develop with React.js and Node.js?
