How to pass models from API to components

Question

What's the best way for transferring models between backend and frontend.

• Is it better to clone the backend ones in frontend even if not all properties are used ?
• Or use DTOs to transfer only necessary properties for each use-case ?

If there is a best practice, design-pattern or any other suggestion I'm interested to know.

For information my stack is Spring Boot and Angular 6.
