Dark Mode & Theming System

Overview

A robust theming system allows users to choose between light, dark, and system-preference modes. We use next-themes for theme state management and CSS custom properties for dynamic styling.

Setup with next-themes

Installation

npm install next-themes

Theme Provider Setup

// components/providers/theme-provider.tsx
"use client";

import { ThemeProvider as NextThemesProvider } from "next-themes";
import type { ThemeProviderProps } from "next-themes";

/**
 * Theme provider wrapper for next-themes.
 * Manages light/dark/system theme preferences.
 */
export function ThemeProvider({ children, ...props }: ThemeProviderProps) {
  return (
    <NextThemesProvider
      attribute="class" // Use class-based dark mode
      defaultTheme="system" // Respect system preference
      enableSystem // Allow system theme detection
      disableTransitionOnChange // Prevent flash during theme change
      {...props}
    >
      {children}
    </NextThemesProvider>
  );
}

Root Layout Integration

// app/layout.tsx
import { ThemeProvider } from "@/components/providers/theme-provider";

export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html lang="en" suppressHydrationWarning>
      <body className="bg-white text-zinc-900 dark:bg-zinc-950 dark:text-zinc-50">
        <ThemeProvider>{children}</ThemeProvider>
      </body>
    </html>
  );
}

Note: suppressHydrationWarning is required on <html> to prevent hydration mismatch from the injected script.

Theme Toggle Component

Basic Toggle

// components/theme-toggle.tsx
"use client";

import { useTheme } from "next-themes";
import { useEffect, useState } from "react";
import { Sun, Moon, Monitor } from "lucide-react";

/**
 * Theme toggle button with three states: light, dark, system.
 * Handles hydration mismatch gracefully.
 */
export function ThemeToggle() {
  const [mounted, setMounted] = useState(false);
  const { theme, setTheme } = useTheme();

  // Prevent hydration mismatch
  useEffect(() => {
    setMounted(true);
  }, []);

  if (!mounted) {
    // Render placeholder with same dimensions to prevent layout shift
    return (
      <button
        className="h-10 w-10 rounded-lg bg-zinc-100 dark:bg-zinc-800"
        aria-label="Toggle theme"
        disabled
      />
    );
  }

  return (
    <button
      onClick={() => {
        if (theme === "dark") setTheme("light");
        else if (theme === "light") setTheme("system");
        else setTheme("dark");
      }}
      className="flex h-10 w-10 items-center justify-center rounded-lg bg-zinc-100 text-zinc-600 transition-colors hover:bg-zinc-200 dark:bg-zinc-800 dark:text-zinc-400 dark:hover:bg-zinc-700"
      aria-label={`Current theme: ${theme}. Click to change.`}
    >
      {theme === "dark" ? (
        <Moon className="h-5 w-5" />
      ) : theme === "light" ? (
        <Sun className="h-5 w-5" />
      ) : (
        <Monitor className="h-5 w-5" />
      )}
    </button>
  );
}

Animated Toggle with Framer Motion

// components/theme-toggle-animated.tsx
"use client";

import { useTheme } from "next-themes";
import { useEffect, useState } from "react";

export function ThemeToggleAnimated() {
  const [mounted, setMounted] = useState(false);
  const { resolvedTheme, setTheme } = useTheme();

  useEffect(() => {
    setMounted(true);
  }, []);

  if (!mounted) {
    return (
      <div className="h-10 w-10 rounded-full bg-zinc-200 dark:bg-zinc-800" />
    );
  }

  const isDark = resolvedTheme === "dark";

  return (
    <button
      onClick={() => setTheme(isDark ? "light" : "dark")}
      className="relative flex h-10 w-10 items-center justify-center rounded-full bg-zinc-100 dark:bg-zinc-800"
      aria-label={`Switch to ${isDark ? "light" : "dark"} mode`}
    >
      <AnimatePresence mode="wait" initial={false}>
        <motion.div
          key={resolvedTheme}
          initial={{ y: -20, opacity: 0, rotate: -90 }}
          animate={{ y: 0, opacity: 1, rotate: 0 }}
          exit={{ y: 20, opacity: 0, rotate: 90 }}
          transition={{ duration: 0.2 }}
        >
          {isDark ? (
            <Moon className="h-5 w-5 text-zinc-300" />
          ) : (
            <Sun className="h-5 w-5 text-amber-500" />
          )}
        </motion.div>
      </AnimatePresence>
    </button>
  );
}
