Node.js API Masterclass with Express and MongoDB - Sign & Get JSON Web Token

The video tutorial explains how to handle JSON Web Tokens (JWT) in a Node.js application using Mongoose. It covers creating a Mongoose method to generate JWTs, signing the token with a secret, and setting an expiration time. The tutorial also demonstrates integrating this method into a controller and testing the token generation. Finally, it discusses setting up middleware to handle user login and token verification.

Why is it recommended to keep controller methods light in a Mongoose application?

• To improve the readability of the code

• To ensure faster execution of the code

• To reduce the number of lines in the code

• To make the code more secure

What is the primary purpose of the payload in a JSON Web Token?

• To store the token's expiration time

• To include the user's ID and other data

• To define the token's algorithm

• To verify the token's signature

Which part of a JWT contains the algorithm and token type?

• Header

• Payload

• Signature

• Footer

What package is used to sign a JWT in the tutorial?

• jsonwebtoken

• jwt-sign

• jwt-creator

• tokenizer

Where should the secret key for signing a JWT be stored?

• In the user's profile

• In the database

• In the config file or environment variables

• In the controller method

What is the benefit of setting an expiration time for a JWT?

• It makes the token easier to decode

• It enhances the security of the token

• It reduces the size of the token

• It allows the token to be reused

How is the JWT signing method called in the controller?

• Through a middleware function

• As a method on the user instance

• Directly from the JWT package

• Using a static method on the model
