How can I secure my Node.js application with MySQL?

To secure your Node.js application with MySQL, you should implement prepared statements to prevent SQL injection, use environment variables for sensitive information, and ensure your database is not publicly accessible.

What are prepared statements and how do they work?

Prepared statements are precompiled SQL statements that allow you to execute the same query multiple times with different parameters. They help prevent SQL injection by separating SQL logic from data.

Are there any libraries you recommend for this?

Yes, you can use libraries like Sequelize or Knex.js for ORM capabilities, which support prepared statements and help manage database interactions securely.

What about user authentication?

For user authentication, consider using libraries like Passport.js or JWT (JSON Web Tokens) for secure token-based authentication.
