Model-view-update
Model-View-Update is a unidirectional user-interface architecture in which a model holds state, a view renders it and emits messages, and an update function produces revised state.
.NET MAUI in Action
MVU is a unidirectional UI architecture in which an immutable model is replaced by updates and the view renders the resulting state.
- How it is used
- Uses MVU as a .NET MAUI alternative to MVVM for state-based interfaces and code-defined UI.
- How deep it goes
- Defines immutable state and one-way flow, but stops short of implementation guidance.
- Examples
- Illustrates MVU with a state-flow diagram and names Comet and Fabulous as .NET MAUI implementations.
- What you can do after
- Evaluate MVU against MVVM when choosing a .NET MAUI UI architecture.
F# in Action: A Revised Edition of Get Programming with F#
The Model-View-Update pattern is a unidirectional architecture in which a model holds application state, a view renders it and emits messages, and an update function produces revised state.
- How it is used
- Structures F# frontend applications by routing UI actions through a single update function.
- How deep it goes
- Defines all three components and their data flow, then stops short of a full implementation.
- Examples
- Uses an e-commerce basket with EmptyBasket and AddItemToBasket commands to illustrate state changes.
- What you can do after
- Apply it via Elmish to structure frontend interfaces and manage asynchronous UI actions.
