Logging in Users

This video tutorial guides users through creating a login endpoint for an application. It covers setting up a new route in the user router, creating a reusable function for user authentication, and implementing methods in the user schema. The tutorial emphasizes error handling, response management, and testing the login functionality using Postman. It also highlights the importance of ensuring email uniqueness in the database to prevent duplicate accounts.

What is the primary purpose of the new endpoint introduced in the video?

• To register new users

• To enable users to log in with their existing accounts

• To allow users to reset their passwords

• To delete user accounts

What method is used to compare the plaintext password with the hashed password?

• password.compare

• crypto.compare

• hash.compare

• bcrypt.compare

Why is a reusable function preferred for finding users by credentials?

• It reduces code duplication and increases maintainability

• It is faster than writing code directly in the route

• It is a requirement of the framework

• It allows for more complex password hashing

What is the role of 'user schema dot statics' in the user model?

• To define static methods accessible on the model

• To manage user sessions

• To store user passwords

• To handle database connections

What happens if no user is found with the provided email during login?

• The user is automatically registered

• An error is thrown indicating login failure

• The system retries with a different email

• A default user profile is returned

Why is it important to ensure email uniqueness in the user registration process?

• To simplify password recovery

• To allow multiple users to share an account

• To speed up the login process

• To prevent duplicate user accounts

What is the significance of setting the email property to unique in the Mongoose schema?

• It speeds up database queries

• It allows multiple users to have the same email

• It encrypts the email addresses

• It ensures each email is unique across users

What tool is used to test the login functionality in the video?

• Swagger

• cURL

• Postman

• Insomnia

What response code is expected when a login attempt is successful?

• 201

• 400

• 404

• 200

What should be the response when the email and password do not match any user?

• A redirect to the registration page

• A success message

• A generic error message

• A detailed error message
