What are some common mistakes when using ORMs in Node.js?

What are some common mistakes when using ORMs in Node.js?

Some common mistakes include not understanding lazy loading, over-fetching data, and ignoring query optimization.

Can you explain lazy loading and why it's a mistake?

Lazy loading can lead to performance issues if not managed properly, as it fetches data only when accessed, potentially causing multiple database calls.

What about over-fetching data? How can I avoid that?

Over-fetching occurs when you retrieve more data than needed. To avoid it, use specific queries to fetch only the required fields.

Are there any best practices for using ORMs in Node.js?

Yes, some best practices include using transactions for batch operations, indexing your database, and keeping your models lean.
