## About
FuncUI is a thin layer built on top of [AvaloniaUI](https://github.com/AvaloniaUI/Avalonia). It contains abstractions
for writing UI applications in different programming styles. It also contains a component & state management system.

FuncUI mostly consists of:
- Virtual DOM
- View DSL
- Component model

## Resources

- 💨 [Getting started](https://funcui.avaloniaui.net)

- 📚 [Documentation](https://funcui.avaloniaui.net/)

- 📓 [Examples](https://github.com/fsprojects/Avalonia.FuncUI/tree/master/src/Examples)

## Contributing
Please contribute to this library through issue reports, pull requests, code reviews, documentation, and discussion.

## Examples
### Example using components
A simple counter made with the component library:

``` f#
type Components =
static member Counter () =
Component (fun ctx ->
let state = ctx.useState 0

DockPanel.create [
DockPanel.children [
Button.create [
Button.onClick (fun _ -> state.Set(state.Current - 1))
Button.content "click to decrement"
]
Button.create [
Button.onClick (fun _ -> state.Set(state.Current + 1))
Button.content "click to increment"
]
TextBlock.create [
TextBlock.dock Dock.Top
TextBlock.text (string state.Current)
]
]
]
)
```

Find more examples using components in the [Components Examples folder](https://github.com/fsprojects/Avalonia.FuncUI/tree/master/src/Examples/Component%20Examples).

### Example using Elmish
The same counter as above but using the `Avalonia.FuncUI.Elmish` package:

```f#
module Counter =
type CounterState = { count : int }
let init = { count = 0 }
type Msg = Increment | Decrement

let update (msg: Msg) (state: CounterState) : CounterState =
match msg with
| Increment -> { state with count = state.count + 1 }
| Decrement -> { state with count = state.count - 1 }

let view (state: CounterState) (dispatch): IView =
DockPanel.create [
DockPanel.children [
Button.create [
Button.onClick (fun _ -> dispatch Increment)
Button.content "click to increment"
]
Button.create [
Button.onClick (fun _ -> dispatch Decrement)
Button.content "click to decrement"
]
TextBlock.create [
TextBlock.dock Dock.Top
TextBlock.text (sprintf "the count is %i" state.count)
]
]
]
```
