Node.js API Masterclass with Express and MongoDB - User Register & Encrypting Passwords

The video tutorial covers setting up a user registration system using Mongoose, focusing on keeping controllers clean by using middleware for password hashing. It demonstrates testing the registration process and error handling using Postman. The tutorial also explains how to implement password encryption with bcrypt and outlines future steps to incorporate JSON web tokens for authentication and route protection.

What is the primary reason for using middleware in the registration process?

• To keep the controllers clean and handle tasks like password hashing

• To directly manage user input validation

• To store user data in a temporary cache

• To automatically generate user IDs

Which tool is used to test the registration process by sending HTTP requests?

• Insomnia

• cURL

• Swagger

• Postman

What happens if you try to set the user role to 'admin' during registration?

• The role is automatically set to 'user'

• An error is returned indicating an invalid role

• The request is ignored

• The user is registered with admin privileges

Which library is used for password encryption in this tutorial?

• bcrypt.js

• bcrypt

• argon2

• crypto

What is the recommended number of rounds for generating a salt with bcrypt.js?

• 20

• 15

• 10

• 5

What is the purpose of implementing JSON web tokens in the application?

• To authenticate users and protect routes

• To store user preferences

• To encrypt user passwords

• To manage user sessions

Which of the following is a route that should be protected using custom middleware?

• Viewing a public profile

• Adding a boot camp
