πŸ’» Reactive HTML Server Side Rendered by GoLang over WebSockets πŸš€

Use Go and Zero JavaScript to program reactive front-ends!

  1. Render Server Side HTML
  2. Connect to same server using Websocket
  3. Send user events
  4. Change state of component in server
  5. Render Component and get diff
  6. Update instructions are sent to the browser

Getting Started

Any suggestions are absolutely welcome

This project it's strongly inspired by Elixir Phoenix LiveView.

Component Example

package components 

import (
	"github.com/brendonmatos/golive"
	"time"
)

type Clock struct {
	golive.LiveComponentWrapper
	ActualTime string
}

func NewClock() *golive.LiveComponent {
	return golive.NewLiveComponent("Clock", &Clock{})
}

func (t *Clock) Mounted(_ *golive.LiveComponent) {
	go func() {
		for {
			t.ActualTime = time.Now().Format(time.RFC3339Nano)
			time.Sleep((time.Second * 1) / 60)
			t.Commit()
		}
	}()
}

func (t *Clock) TemplateHandler(_ *golive.LiveComponent) string {
	return `
		<div>
			<span>Time: {{ .ActualTime }}</span>
		</div>
	`
}

Server Example

  
package main

import (
	"github.com/brendonmatos/golive"
	"github.com/brendonmatos/golive/examples/components"
	"github.com/gofiber/fiber/v2"
	"github.com/gofiber/websocket/v2"
)

func main() {
	app := fiber.New()
	liveServer := golive.NewServer()

	app.Get("/", liveServer.CreateHTMLHandler(components.NewClock, golive.PageContent{
		Lang:  "us",
		Title: "Hello world",
	}))

	app.Get("/ws", websocket.New(liveServer.HandleWSRequest))

	_ = app.Listen(":3000")
}

That's it!
