What are the best practices for using Express with a database?

When using Express with a database, consider these best practices: use connection pooling, handle errors gracefully, and validate user input.

Can you explain why connection pooling is important?

Connection pooling improves performance by reusing database connections, reducing the overhead of establishing new connections for each request.

What are some common error handling strategies?

Common strategies include using middleware for centralized error handling, logging errors, and sending user-friendly error messages.

How can I validate user input effectively?

You can use libraries like Joi or express-validator to define schemas and validate incoming data before processing it.
