SwiftUI and Node.js Full Stack - Build Twitter - iOS 16 - toJSON

The video tutorial addresses a common issue in programming where sensitive user data, such as passwords, is inadvertently shared with the client side during a fetch request. The instructor explains how to modify the user schema to exclude passwords by redefining the toJSON function. This involves converting JSON data into an object, removing the password, and then returning the modified object. The solution is tested using Postman to ensure passwords are not exposed. Future episodes will cover authentication and token management to further enhance security.

Why is it problematic to fetch all user information, including passwords, in a request?

• It slows down the response time.

• It makes the code more complex.

• It can lead to security vulnerabilities.

• It increases the load on the server.

What is the purpose of redefining the toJSON function in the user schema?

• To add new features to the application.

• To simplify the code structure.

• To enhance the performance of the application.

• To ensure passwords are not included in the client response.

What is the first step in handling user data securely?

• Send the data to the client as is.

• Encrypt the user data.

• Store the data in a database.

• Convert the JSON data to a user object.

Why do we delete the password from the user object before sending it to the client?

• To improve the speed of data processing.

• To prevent unauthorized access to sensitive information.

• To reduce the size of the data being sent.

• To comply with data storage regulations.

What happens if the line deleting the password is commented out?

• The application will throw an error.

• The password will be included in the client response.

• The password will still be excluded from the response.

• The request will be denied.

What is the next topic to be covered after handling user data?

• Database optimization.

• User interface design.

• Authentication and token management.

• Server-side scripting.

Why should tokens not be shared with the client side?

• They are only used for server-side operations.

• They are too large to be sent.

• They contain sensitive information.

• They are not compatible with client-side technology.
