What are the best practices for querying with Mongoose?

When querying with Mongoose, it's important to use lean queries for better performance, avoid unnecessary data retrieval, and utilize indexes.

Can you explain what lean queries are?

Lean queries in Mongoose return plain JavaScript objects instead of Mongoose documents, which reduces overhead and improves performance.

How can I implement indexing in my Mongoose models?

You can implement indexing by using the index property in your schema definition, like this: name: { type: String, index: true }.

Are there any specific query methods I should avoid?

Yes, avoid using exec() unnecessarily, and be cautious with populate() as it can lead to performance issues if overused.
