Vue 3 Dark Mode with Tailwind CSS Example

In this section, we’ll delve into implementing dark mode in Vue 3 using Tailwind CSS 3. We’ll leverage the VueUse library for enabling dark mode functionality. Before diving in, ensure you’ve installed and set up Tailwind CSS with Vue 3.

Install VueUse For Dark Mode

Run below command install vueuse.

npm i @vueuse/core

Add Dark Mode class in tailwind.config.js.

/** @type {import('tailwindcss').Config} */
module.exports = {
  darkMode: 'class',
  content: ["./index.html", "./src/**/*.{vue,js,ts,jsx,tsx}"],
  theme: {
    extend: {},
  plugins: [],

Add Dark Mode using vueUse.

<script setup>
import { useDark, useToggle } from '@vueuse/core';

const isDark = useDark();
const toggleDark = useToggle(isDark);

    <div class="flex justify-center items-center h-screen flex-col">
        <button @click="toggleDark()" class="px-4 py-2 text-white bg-gray-600 dark:bg-purple-700">
