DTO vs ViewModel
Developers should use DTOs when building applications with layered architectures, such as in microservices, REST APIs, or MVC frameworks, to decouple the internal domain model from the external interface and optimize data transfer over networks meets developers should learn viewmodel to build robust android apps that handle configuration changes gracefully without losing user data, improving user experience and reducing crashes. Here's our take.

DTO
Nice PickDevelopers should use DTOs when building applications with layered architectures, such as in microservices, REST APIs, or MVC frameworks, to decouple the internal domain model from the external interface and optimize data transfer over networks
Pros
- +They are particularly useful for reducing overhead in remote calls, preventing over-fetching or under-fetching of data, and enhancing security by exposing only necessary data to clients
- +Related to: design-patterns, rest-api
Cons
- -Specific tradeoffs depend on your use case
ViewModel
Developers should learn ViewModel to build robust Android apps that handle configuration changes gracefully without losing user data, improving user experience and reducing crashes
Pros
- +It is essential for implementing the Model-View-ViewModel (MVVM) architecture, which enhances testability and maintainability by decoupling UI logic from data operations
- +Related to: android-architecture-components, mvvm-architecture
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use DTO if: You want they are particularly useful for reducing overhead in remote calls, preventing over-fetching or under-fetching of data, and enhancing security by exposing only necessary data to clients and can live with specific tradeoffs depend on your use case.
Use ViewModel if: You prioritize it is essential for implementing the model-view-viewmodel (mvvm) architecture, which enhances testability and maintainability by decoupling ui logic from data operations over what DTO offers.
