Web Development with Node.JS and MongoDB (Video 21)

This video tutorial covers the use of Mongoose, an ODM for MongoDB in Node.js applications. It explains how to install Mongoose, set up database connections, and define schemas and models. The tutorial also covers user authentication, adding custom and static methods, using virtuals and middleware, and updating documents. Security measures against injection attacks are discussed. The video concludes with a summary and a preview of the next topic, RESTful APIs.

What is one of the main benefits of using Mongoose in application development?

• It eliminates the need for a database.

• It provides schema-based modeling for application data.

• It is only compatible with SQL databases.

• It requires no installation.

Which command is used to install Mongoose?

• npm install mongoose

• npm start mongoose

• npm update mongoose

• npm remove mongoose

What is the first step in defining a model with Mongoose?

• Running a query

• Creating a schema

• Setting up middleware

• Creating a database

What method is used to register a new user with Mongoose?

• User.create()

• User.save()

• User.add()

• User.register()

How can you add a custom method to a Mongoose document?

• By directly modifying the database

• By using the 'methods' object on the schema

• By creating a new schema

• By using the 'statics' object on the schema

What is a virtual property in Mongoose?

• A property that requires no validation

• A property that is automatically generated by Mongoose

• A property that is not persisted to the database

• A property that is stored in the database

How can you protect a MongoDB application from injection attacks?

• By using the $in operator

• By using SQL commands

• By storing data in plain text

• By disabling all queries
