SwiftlyGo

Build beautiful WebAssembly apps in Go, swiftly and declaratively.

---

🚀 Overview

SwiftlyGo is a minimalist UI framework inspired by SwiftUI, powered by Go and WebAssembly. It provides a declarative way to build interactive web applications using idiomatic Go code.

No HTML, no CSS, no JavaScript. Just Go.

---

🧩 Features

• ✅ Declarative UI composition
• 🔁 Reactive state with Observables
• 🧱 Composable widgets: Label, TextField, Button
• 🎯 Fluent modifiers: .Padding(), .Background(), .Center()
• 📦 Single binary output (WASM)
• 🔄 Hot reload dev server with live-rebuild
• 🔧 Zero-config startup

---

📦 Installation

git clone https://github.com/yourname/swiftlygo

✍️ Example

package main

import (
	"fmt"
	"gocore/core"
	"gocore/ui"
)

func OneWay() {
	source := core.NewObservable("")

	in := ui.NewTextField()
	in.BindTo(source)

	out := ui.NewTextField()

	btn := ui.NewButton("Copy")
	btn.OnClick(func() {
		fmt.Println("Clicked:", source.Get())
		out.SetText(source.Get())
	})

	w := ui.NewWindow()
	w.Add(in, out, btn)
	w.Run()
}

🧪 Roadmap

• Fluent styling modifiers
• Observables and bindings
• Derived computed observables
• Layout containers (e.g., VBox, HBox)
• Router & navigation
• Component lifecycle hooks
• Minimal CSS-in-Go system
