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

Resources

• 💨 Getting started

• 📚 Documentation

• 📖 Control Catalog (Samples of available controls)

• 📓 Examples

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:

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.

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)
 ]
 ]
 ]
