- In Mongoose, a virtual is a property that is not stored in MongoDB. Virtuals are typically used for computed properties on documents.
- Virtuals are document properties that you can get and set but that do not get persisted to MongoDB.
Serialization Tutorial Serialization is the process of mapping an object to a BSON document that can be saved in MongoDB, and deserialization is the reverse process of reconstructing an object from a BSON document. For that reason the serialization process is also often referred to as “Object Mapping.”
Serialization is the process of converting a data object—a combination of code and data represented within a region of data storage—into a series of bytes that saves the state of the object in an easily transmittable form.
Data serialization is the process of converting an object into a stream of bytes to more easily save or transmit it.
Serialization enables us to save the state of an object and recreate the object in a new location. Serialization encompasses both the storage of the object and exchange of data.
Statics are Mongoose's implementation of OOP static functions. You add a static function to your schema, and Mongoose attaches it to any model you compile with that schema.
What is the difference between methods and statics in Mongoose?
Methods operate on an instance of a model. Statics behave as helper functions only and can perform any action you want, including collection level searching. They aren't tied to an instance of a Model. But methods are also defined on models and work on all the instances of that model.
