Naive implementation MVU in Blazor inspired by elmish (without razor syntax).
I want to write applications in C# and Blazor based on model-view-update. If you too, try this.
Its not production ready, its not ready for anything. I just making this in free time.
Just for fun.
The following commands are currently ready:
- None
- OfMsg
- OfFuncEither
- OfFuncPerform
- OfTaskEither
- OfTaskPerform
Just create class and inherintce BlazorishSimpleComponent, in generic parameters add your model and msg. Write your model, like this
public record Model(int Count);And add your messages
public abstract record Msg
{
public sealed record Increment : Msg;
public sealed record Decrement : Msg;
public sealed record Reset : Msg;
}After that implement abstract methods: Update, Init and View.
protected override Model Init() => new(0);
protected override Model Update(Model model, Msg msg) => msg switch
{
Msg.Increment => model with {Count = model.Count + 1},
Msg.Decrement => model with {Count = model.Count - 1},
_ => model with {Count = 0}
};
protected override Tag View(Model model) =>
div(
children(
h1(
content("Counter")
),
p(
content($"Current count: {model.Count}")
),
btn(
content("Increment"),
classes("btn btn-primary"),
onclick(_ => Dispatch(new Msg.Increment()))
),
btn(
content("Decrement"),
classes("btn btn-primary"),
onclick(_ => Dispatch(new Msg.Decrement()))
),
btn(
content("Reset"),
classes("btn btn-primary"),
onclick(_ => Dispatch(new Msg.Reset()))
)
)
);Also add route attribute to your component
[Route("/counter")]
public class CounterComponent : BlazorishSimpleComponent<CounterComponent.Model, CounterComponent.Msg>Optional, add static using if you don't want write static class for dsl
global using static Blazorish.Html.Tag;
global using static Blazorish.Html.Attr;Congratulations! You create blazor component with MVU architecture.
Blazorish.Samples project has examples based on defaut blazor WASM template.
