themetoggle

ThemeToggle

Signal-driven component to toggle the application theme (dark / light).

Features

• 2 states: dark and light. Defaults to light when nothing is saved. There is no auto/OS-preference state — if an app wants to seed the theme from prefers-color-scheme, resolve that outside this component (e.g. by writing to localStorage/data-theme before mounting ThemeToggle).
• Automatic persistence in localStorage via Init.
• Fixed floating button.
• Signal-driven: updates icon and labels surgically without re-rendering the whole button.

Usage

import (
	"github.com/tinywasm/components/themetoggle"
	"github.com/tinywasm/dom"
)

func main() {
	ts := &themetoggle.ThemeToggle{}
	dom.Append("body", ts)
	select {}
}
