What is mongoose?

Mongoose is an Object Document Mapper (ODM) for MongoDB and Node.js. It provides a straightforward, schema-based solution to model your application data. Mongoose allows you to define objects with a strongly-typed schema mapped to a MongoDB document. This makes it easy to work with MongoDB and perform CRUD operations, validation, and more.

Mongoose provides a powerful query API for MongoDB, modelled after the popular MongoDB shell methods. It supports all MongoDB data types, including ObjectId, Date, and more. It also supports advanced features such as middleware, custom methods, and more.

With Mongoose, you can define your schema using a simple and intuitive syntax and then use it to create model instances that you can save, retrieve, update, and delete from your MongoDB database.

Mongoose also provides pre-save validation functionality and middleware hooks that can run before/after certain operations. It offers more features like population and aggregation, allowing you to work with related documents more conveniently.

In short, Mongoose is a powerful tool that provides a simple, elegant API for interacting with MongoDB, making it easy to work with your data and perform CRUD operations.
