GopherJS bindings for Facebook React.
NOTE: Still early and not production ready.
Examples
NOTE: Make sure that your GopherJS is up-to-date before running these: go get -u github.com/gopherjs/gopherjs
For a live demo of the examples below, see http://bego.io/gr/ (may not be up-to-date).
There are some runnable examples in /examples. Just navigate to that folder and do a:
gopherjs serve
Then navigate to http://localhost:8080/github.com/bep/gr/examples/.
To get a sense of the API, here is the click-counter example:
func main() {
component := gr.New(new(clickCounter))
gr.RenderLoop(func() {
component.Render("react", gr.Props{})
})
}
type clickCounter struct {
*gr.This
}
// Implements the StateInitializer interface.
func (c clickCounter) GetInitialState() gr.State {
return gr.State{"counter": 0}
}
// Implements the Renderer interface.
func (c clickCounter) Render() gr.Component {
counter := c.State()["counter"]
message := fmt.Sprintf(" Click me! Number of clicks: %v", counter)
elem := el.Div(
el.Button(
gr.CSS("btn", "btn-lg", "btn-primary"),
gr.Style("color", "orange"),
gr.Text(message),
evt.Click(c.onClick)))
return examples.Example("Click Counter", elem)
}
func (c clickCounter) onClick(event *gr.Event) {
c.SetState(gr.State{"counter": c.State().Int("counter") + 1})
}
// Implements the ShouldComponentUpdate interface.
func (c clickCounter) ShouldComponentUpdate(next gr.Cops) bool {
return c.State().HasChanged(next.State, "counter")
}

Inspiration
This project is highly inspired by Vecty, a promising and pure Go React-like framework. If you're not heavily invested in Facebook's React, take that for a spin.
