What You Need for Tailwind Nextjs Integration

Before we dive in, here’s what you’ll need:

• Node.js: Both TailwindCSS and Next.js require Node.js. You can check if it’s installed by running node -v in your terminal.
• Basic Understanding of JavaScript and React: Familiarity with JavaScript and React is important since Next.js is built on React.
• Familiarity with Next.js: While it’s helpful to know the basics of Next.js, don’t worry if you’re still getting familiar with it—this guide will walk you through the setup process.

Why Choose Tailwind Nextjs Combo?

When you combine Tailwind with Nextjs, you get a powerful combination for building fast, scalable websites. Next.js provides performance optimizations like server-side rendering (SSR) and static site generation (SSG), while TailwindCSS allows you to design directly in your HTML using utility classes.

Benefits of Using TailwindCSS with Next.js:

• Faster Development: Tailwind’s utility-first approach allows for rapid development, while Next.js provides optimizations like SSR and SSG to enhance performance.
• Better Developer Experience: Next.js features like fast refresh, routing, and simple API creation, combined with Tailwind’s responsive utilities, make for a smooth and efficient workflow.
• Scalability: Both TailwindCSS and Next.js are built to handle large projects with ease, ensuring that your website can grow as your needs evolve.

Together, these tools streamline both development and performance, making them an excellent choice for modern web applications.

Step-by-Step Guide to Setting Up TailwindCSS v4 with Next.js

Now that we’ve explored why Tailwind CSS and Next.js make a powerful combination, it’s time to dive into the process of setting them up together. Let’s walk through the steps to integrate Tailwind CSS with Next.js and get your project up and running smoothly.

Create A new Next.js Project:

First, let’s start by setting up a new Next.js project. Head to your terminal and type the following command:

npx create-next-app my-project
cd my-project

Install Tailwind CSS

In your Next.js project, install Tailwind CSS and its required dependencies by running the command for @tailwindcss/postcss via npm.

npm install tailwindcss @tailwindcss/postcss postcss

This will generate a postcss.config.js file in the root directory of your project.

Configure PostCSS Plugins

In the root directory of your project, create a postcss.config.mjs file and include the @tailwindcss/postcss plugin in your PostCSS setup.

const config = {
  plugins: {
    "@tailwindcss/postcss": {},
  },
};
export default config;

Import Tailwind CSS

In the ./src/app/globals.css file, add a @import statement that includes Tailwind CSS.

@import "tailwindcss";

Run the Development Server

Next, launch the development server to see Tailwind CSS in action:

npm run dev

Your Next.js project is now successfully integrated with Tailwind CSS. You can start using Tailwind’s utility classes to style your components.

Creating a Profile Card Using TailwindCSS Utilities

Create a new file named ProfileCard.tsx for the component.

Create a ProfileCard.tsx file inside the /src/components directory of your project.

import Image from "next/image";

export default function ProfileCard() { 
	return (
		<div className="flex flex-col items-center justify-center max-w-md p-6 bg-white rounded-lg shadow-md gap-4 text-center">
			<Image src="/avatar.png" alt="user" width="50" height="50" className="rounded-full"/>
			<div className="flex flex-col items-center">
				<h2 className="text-xl font-semibold">John Doe</h2>
				<p className="text-gray-500">Software Engineer</p>
			</div>
			<div className="flex gap-2">
				<div className="flex flex-col items-center px-4">
					<span className="text-lg font-semibold">120</span>
					<span className="text-gray-500">Posts</span>
				</div>
				<div className="flex flex-col items-center px-4">
					<span className="text-lg font-semibold">80k</span>
					<span className="text-gray-500">Following</span>
				</div>
				<div className="flex flex-col items-center px-4">
					<span className="text-lg font-semibold">1.2K</span>
					<span className="text-gray-500">Following</span>
				</div>
			</div>
			<p className="text-gray-500">
				Lorem, ipsum dolor sit amet consectetur adipisicing elit. Harum animi beatae molestiae quasi fugiat ut.
			</p>
			<button className="bg-purple-400 text-white px-6 py-3 rounded-full hover:bg-purple-500 transition duration-300 active:scale-95">
				View Profile
			</button>
		</div>
	);
}

Bring the ProfileCard component into the file where you want to use it

Currently, we are importing it into the /src/app/page.tsx file.

import ProfileCard from "@/components/ProfileCard";

export default function Home() {
  return (
    <div className="flex h-screen justify-center items-center"><ProfileCard/></div>
  );
}

Run the Development Server

Start the development server to view your ProfileCard In action.

npm run dev

Then, open your browser and navigate to http://localhost:3000/ to see the result.

npm install flyonui

Add the FlyonUI plugin

Add the FlyonUI plugin to your global.css file.

@plugin "flyonui";
@import "flyonui/variants.css";
@source "./node_modules/flyonui/flyonui.js"; // Add only if node_modules is gitignored

Create FlyonUI JavaScript loader

Create a FlyonuiScript.tsx file in your project, for example, under src/components/.

'use client';

import { usePathname } from 'next/navigation';
import { useEffect } from 'react';

import { IStaticMethods } from 'flyonui/flyonui';
declare global {
  interface Window {
    HSStaticMethods: IStaticMethods;
  }
}

async function loadFlyonUI() {
  return import('flyonui/flyonui');
}

export default function FlyonuiScript() {
  const path = usePathname();

  useEffect(() => {
    const initFlyonUI = async () => {
      await loadFlyonUI();
    };

    initFlyonUI();
  }, []);

  useEffect(() => {
    setTimeout(() => {
      if (
        window.HSStaticMethods &&
        typeof window.HSStaticMethods.autoInit === 'function'
      ) {
        window.HSStaticMethods.autoInit();
      }
    }, 100);
  }, [path]);

  return null;
}

Add the FlyonUI JavaScript loader

Incorporate the FlyonUI JavaScript loader into your app’s entry point, such as root_directory/app/layout.tsx.

...

import FlyonuiScript from '../components/FlyonuiScript';

...

export default function RootLayout({ children, }: { children: React.ReactNode; }) {
  return (
    <html>
      ...
      <body>
        ...
        <FlyonuiScript />
      </body>
    </html>
  );
}

FlyonUI is also available in pro version. It includes

• Tailwind Blocks
• Tailwind Figma Design System

Refactor the ProfileCard by integrating FlyonUI components

Let’s utilize FlyonUI components like Avatar, Card, and Button, which are pre-styled and help save a lot of development time.

export default function ProfileCard() { 
	return (
			<div className="card sm:max-w-sm">
				<div className="card-body items-center text-center gap-4">
					<div className="avatar">
						<div className="size-14 rounded-full">
							<img src="https://cdn.flyonui.com/fy-assets/avatar/avatar-1.png" alt="avatar" />
						</div>
					</div>
					<div className="flex flex-col items-center">
						<h2 className="text-xl font-semibold text-base-content">John Doe</h2>
						<p className="text-gray-500">Software Engineer</p>
					</div>
					<div className="flex gap-2">
						<div className="flex flex-col items-center px-4">
							<span className="text-lg font-semibold text-base-content">120</span>
							<span className="text-gray-500">Posts</span>
						</div>
						<div className="flex flex-col items-center px-4">
							<span className="text-lg font-semibold text-base-content">80k</span>
							<span className="text-gray-500">Following</span>
						</div>
						<div className="flex flex-col items-center px-4">
							<span className="text-lg font-semibold text-base-content">1.2K</span>
							<span className="text-gray-500">Following</span>
						</div>
					</div>
					<p>
						Lorem, ipsum dolor sit amet consectetur adipisicing elit. Harum animi beatae molestiae quasi fugiat ut.
					</p>

					<div className="card-actions">
						<button className="btn btn-primary rounded-full">View Profile</button>
					</div>
				</div>
			</div>
	);
}

This is how your Profile Card will appear.
