What are the best practices for using Node.js with PostgreSQL?

Some best practices include using connection pooling, handling errors properly, and using parameterized queries to prevent SQL injection.

Can you explain connection pooling?

Connection pooling allows you to reuse database connections, which improves performance by reducing the overhead of establishing new connections.

What about error handling?

Error handling is crucial; always catch errors and log them appropriately. Use try-catch blocks and handle specific error types.

How can I prevent SQL injection?

Use parameterized queries or prepared statements to ensure that user input is treated as data, not executable code.
