Mongoose, a popular ODM (Object Data Modeling) library for MongoDB in Node.js, provides powerful querying capabilities to work with complex document structures. In this article, we'll explore some advanced querying features in Mongoose, including $elemMatch, aggregation pipelines, and bulkWrite operations. These techniques are essential for building efficient and scalable applications.

When deciding between Prisma and Mongoose for a MongoDB-based application, there are several factors to consider. Both are powerful tools, but they are designed with different paradigms and use cases in mind. Below is a breakdown to help you understand when you might prefer one over the other.

Mongoose pre hooks are middleware functions that run before certain operations, such as saving or validating a document. They are useful for a variety of tasks, including data validation, transformation, and managing related data.

Why Use Pre Hooks?​

Pre hooks allow you to:

• Validate or sanitize data before it’s saved to the database.
• Automatically perform actions like hashing passwords.
• Clean up related data before deletion.
• Modify queries before executing them.
