Go-app is a package for building progressive web apps (PWA) with the Go programming language (Golang) and WebAssembly (Wasm).

Shaping a UI is done by using a declarative syntax that creates and compose HTML elements only by using the Go programing language.

It uses Go HTTP standard model.

An app created with go-app can out of the box run in its own window, supports offline mode, and are SEO friendly.

Install

go-app requirements:

go mod init
go get -u github.com/maxence-charriere/go-app/v8/pkg/app

Declarative syntax

Go-app uses a declarative syntax so you can write reusable component-based UI elements just by using the Go programming language.

Here is a Hello World component that takes an input and displays its value in its title:

type hello struct {
	app.Compo

	name string
}

func (h *hello) Render() app.UI {
	return app.Div().Body(
		app.H1().Body(
			app.Text("Hello, "),
			app.If(h.name != "",
				app.Text(h.name),
			).Else(
				app.Text("World!"),
			),
		),
		app.P().Body(
			app.Input().
				Type("text").
				Value(h.name).
				Placeholder("What is your name?").
				AutoFocus(true).
				OnChange(h.ValueTo(&h.name)),
		),
	)
}

Standard HTTP

Apps created with go-app complies with Go standard HTTP package interfaces.

func main() {
    // Components routing:
	app.Route("/", &hello{})
	app.Route("/hello", &hello{})
	app.RunWhenOnBrowser()

    // HTTP routing:
	http.Handle("/", &app.Handler{
		Name:        "Hello",
		Description: "An Hello World! example",
	})

	if err := http.ListenAndServe(":8000", nil); err != nil {
		log.Fatal(err)
	}
}
