- View components are the next generation of view layer that provide object-oriented features like inheritance and encapsulation, making views more testable and maintainable compared to traditional view helpers. - "Cells" are a type of view component that function as a small MVC stack within a view, keeping presentation logic separate from views. They are well-suited for layouts, generic views, widgets, and other cases with complex view logic. - Using cells/view components can avoid issues like duplicated views and file structure maintenance when dealing with reusable UI components across many views. Defining a base component logic and partials allows inheritance and customization to reduce maintenance costs.
Inherited views
- 2. When we are using MVC frameworks only view layer does not correspond to the OO principles
- 3. What frameworks give us from the box ? view rendering ? partial rendering ? support of helper methods
- 4. Biggest disadvantage of the view layer ? does not support unit testing
- 5. Disadvantages of helpers ? do not allow inheritance ? methods are calling without a receiver ? collision between helpers with similar methods
- 6. We can replace helpers to decorators and improve presentation logic
- 7. Advantages of decorators ? allow inheritance ? allow encapsulation ? friendly for unit testing ? does not mutate decorated object ? does not change the behavior of decorated object
- 8. Decorators has advantages over helpers
- 9. But decorators are not developed for view layer
- 10. View Components next generation of view layer
- 12. Advantages of ¡®cells¡¯ ? basically a small MVC stack ? own render engine ? OOP features ? separate presentation from the view logic
- 13. Bene?ts for application structure ? slim controllers ? clear views ? maintainability
- 14. When do we need such approach?
- 15. Cells applicable for ? layouts ? generic views ? complex view logic ? widgets
- 16. Simple example
- 17. Typical situation ? duplicated views for some UI part ? each view can render speci?c partials ? each partial can build speci?c content
- 18. Every new case expects change of current condition state and ?le structure
- 19. Somebody should maintain this stuff
- 20. To avoid this painful we can use the power of components
- 27. Conclusions ? separated from presentation logic ? easy maintenance ? test coverage ? isolated dependencies
- 29. Questions?
