Practical GraphQL - Become a GraphQL Ninja - Preparing the model for authentication

The video tutorial covers extending a user model to include username and password fields, updating dummy data to align with the new model, and implementing password hashing using bcrypt. It explains how to add custom instance methods in SQL Elize and demonstrates the use of async/await for handling promises during password hashing. The tutorial emphasizes the importance of securing passwords by hashing them before database insertion.

Why is it important to set the username field as unique in the user model?

• To prevent users from having passwords

• To allow multiple users to have the same username

• To ensure each user has a distinct identifier

• To make the database queries faster

What should be done to the dummy data file after updating the user model?

• Change all usernames to uppercase

• Remove all validation rules

• Add username and password fields to match the new model

• Delete all existing data

What is a major security risk of storing passwords in plain text?

• It makes password recovery difficult

• It increases the size of the database

• It allows unauthorized access if the database is compromised

• It makes the database slower

What is the purpose of using instance methods in the context of password hashing?

• To create new database tables

• To delete rows from the database

• To perform actions on individual rows during insertion

• To apply hashing to all rows at once

Which JavaScript feature is used to handle promises when hashing passwords?

• Event listeners

• Async/await

• Synchronous functions

• Callbacks

What library is used for hashing passwords in this tutorial?

• HashLib

• bcrypt

• SecureHash

• CryptoJS

Why is it important to avoid using arrow functions when accessing 'this' in JavaScript?

• Arrow functions are not supported in all browsers

• Arrow functions cannot be used in classes

• Arrow functions do not bind 'this' correctly

• Arrow functions are slower
