NestJS #44 - MongoDB & Mongoose | Hooks & Middlewares | Instance, Static & Query Methods | (Hindi)
Mongoose Hooks are useful for running middleware functions before or after a query or operation. We can also add custom methods to Document instance for adding specific functionalities related to documents. Similarly, Mongoose provides the Static methods to bind on Models. There also exists Query Helpers to extend the find queries functionality. This video demonstrates the use of Hooks, Instance methods, Static Methods, and Query Helpers.
