Mongoose ODM

Mongoose is an Object Data Modeling library for MongoDB and Node.js, providing a schema-based solution for modeling application data.

Schemas and Models

Mongoose schemas define the structure of documents, while models provide an interface for creating, querying, and updating data in MongoDB.

Validation

Built-in validation lets developers enforce data rules like required fields, data types, and custom validators before data is saved.

Middleware and Hooks

Mongoose supports middleware functions that run before or after certain operations, useful for tasks like hashing passwords or logging changes.
