Avalonia FuncUI
Develop cross-platform GUI Applications using F# and AvaloniaUI!
(Application was created using Avalonia.FuncUI!)
About
FuncUI is a thin layer built on top of AvaloniaUI. 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

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

Example using Elmish
The same counter as above but using the Avalonia.FuncUI.Elmish
package:
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)
]
]
]
