# go-reactor

Framework for writing completely reactive web applications.

## Hello-World

Simple one page hello world program that counts number of clicks:

```go

package main

import (

	"fmt"

	"sync"

	"github.com/draganm/go-reactor"

)

func main() {

	r := reactor.New()

	r.AddScreen("/", indexScreenFactory)

	r.Serve(":8080")

}

func indexScreenFactory(ctx reactor.ScreenContext) reactor.Screen {

	return &indexScreen{

		ctx: ctx,

	}

}

var indexScreenTemplate = reactor.MustParseDisplayModel(`



	You've clicked hello world:  times



`)


type indexScreen struct {

	sync.Mutex

	ctx          reactor.ScreenContext

	clickCounter int

}

func (i *indexScreen) Mount() {

	i.clickCounter = 0

	i.render()

}

func (i *indexScreen) render() {

	ui := indexScreenTemplate.DeepCopy()

	ui.SetElementText("count", fmt.Sprintf("%d", i.clickCounter))

	i.ctx.UpdateScreen(&reactor.DisplayUpdate{

		Model: ui,

	})

}

func (i *indexScreen) OnUserEvent(evt *reactor.UserEvent) {

	i.Lock()

	defer i.Unlock()

	if evt.ElementID == "hw" {

		i.clickCounter++

		i.render()

	}

}

func (i *indexScreen) Unmount() {}

```
