A declarative and functional web UI framework inspired by The Elm Architecture.
-
Refactor Safety
By leveraging pattern matching and tagged union, exhaustive checks provide a better refactoring experience. MoonBit helps prevent common runtime errors ensuring more robust and reliable code.
-
Maintainable State
The state is globally managed, making it easier to maintain the entire application. By utilizing persistent data structures from
moonbitlang/core/immut, you can implement advanced features such as undo/redo functionality with ease. -
Lightweight Runtime
The generated JavaScript file is 33KB after minified for a project like
src/example/counter, including the virtual DOM.
typealias Int as Model
let model = 0
enum Msg {
Increment
Decrement
}
fn update(msg : Msg, model : Model) -> (Cmd[Msg], Model) {
match msg {
Increment => (none(), model + 1)
Decrement => (none(), model - 1)
}
}
fn view(model : Model) -> Html[Msg] {
div([
h1([text(model.to_string())]),
button(click=Increment, [text("+")]),
button(click=Decrement, [text("-")]),
])
}
fn main {
@tea.startup(model~, update~, view~)
