# Get package.
go get -u -v github.com/murlokswarm/app/...

# Go to your go package.
cd $GOPATH/src/github.com/USERNAME/hello

# Install the required frameworks and generate the app structure.
goapp mac init

// main.go

func main() {
	app.Import(&Hello{})

	app.Run(&mac.Driver{
		OnRun: func() {
			newWindow()
		},

		OnReopen: func(hasVisibleWindow bool) {
			if !hasVisibleWindow {
				newWindow()
			}
		},
	})
}

func newWindow() {
	app.NewWindow(app.WindowConfig{
		Title:           "hello world",
		TitlebarHidden:  true,
		Width:           1280,
		Height:          768,
		BackgroundColor: "#21252b",
		DefaultURL:      "/Hello",
	})
}

type Hello struct {
	Name string
}

func (h *Hello) Render() string {
	return `
<div class="Hello">
	<h1>
		Hello
		{{if .Name}}
			{{.Name}}
		{{else}}
			world
		{{end}}!
	</h1>
	<input value="{{.Name}}" placeholder="Say something..." onchange="Name" autofocus>
</div>
	`
}

# Build the app.
goapp mac build

# Launch the app.
./hello

app.Run starts the app. It takes an app.Driver as argument. Here we use the MacOS driver implementation. See other drivers.

When creating the window, we set the DefaultURL to our Hello component struct name: /Hello. It will load the Hello component when the window is displayed.

Components are structs that implement the app.Component interface.

Render method returns a string that contains HTML5. It can be templated following Go standard template syntax:

• text/template
• html/template

HTML events like onchange are mapped to the targetted component field or method. Here, onchange is mapped to the field Name.

Additionally, CSS files can be dropped in PACKAGEPATH/resources/css/ directory. All .css files within that directory will be included.

See the full example.

A driver contains specific code that allows the app package to work on multiple platforms.

• MacOS
• Web - run on the top of gopherjs

Other drivers will come in the future.
