Introduction

In this guide, you will learn how to set up a modern web application using Vite 8, React 19, Tailwind CSS v4, React Router v7, Lucide React, and React Icons.
Vite offers a fast and efficient development environment, React makes it easy to build dynamic user interfaces,
Tailwind CSS provides a flexible and efficient way to design styles, and both icon libraries give you thousands of ready-to-use icons.

Prerequisites

Before getting started, make sure you have the following installed:

• Node.js (version 18 or higher)
• npm or yarn

You can verify the installation by running the following commands in your terminal:

node -v
npm -v

Creating the Project with Vite

Vite simplifies the configuration of React projects. Below are two options: one for JavaScript projects and another for TypeScript projects.

1. Run the following command to create a new project:

   npm create vite@latest project-name

2. During the setup, you will be prompted to select a framework. Choose React.

3. Next, you will be asked to select a variant. Choose JavaScript or TypeScript, depending on your preference.

4. Navigate to your project folder:

   cd project-name

5. Install the dependencies:

   npm install

Installing React Router

To enable navigation between pages, install React Router v7:

npm install react-router-dom

This will allow you to define and manage routes within your application.

Setting Up Tailwind CSS v4

Tailwind CSS v4 uses a PostCSS plugin for integration — no tailwind.config.js required.

1. Install Tailwind CSS and its PostCSS dependencies:

   npm install -D tailwindcss @tailwindcss/postcss postcss autoprefixer

2. Create a postcss.config.js file at the root of your project:

   export default {
     plugins: {
       '@tailwindcss/postcss': {},
     },
   }

3. Replace all content in src/index.css with a single import:

   @import "tailwindcss";

That's it — no config file needed. Tailwind v4 auto-detects your template files automatically.

Installing Icon Libraries

Lucide React ^1.9.0

Lucide React provides a clean, consistent icon set.

npm install lucide-react

import { Home, Menu, ArrowRight } from 'lucide-react'

<Home size={24} />
<Menu className="w-6 h-6 text-blue-500" />
<ArrowRight size={18} />

React Icons ^5.6.0

React Icons includes icons from Font Awesome, Material Design, Heroicons, and many more.

npm install react-icons

import { FaGithub, FaReact } from 'react-icons/fa'
import { MdHome, MdInfo } from 'react-icons/md'

<FaGithub size={24} />
<MdHome className="text-blue-500" />

Creating Components and Pages

Example Home.tsx (Page):

import { Link } from "react-router-dom";
import { ArrowRight, Info } from "lucide-react";

const Home = () => {
  return (
    <>
      <title>Welcome to my Page</title>
      <meta name="description" content="A shift to something with more potential." />

      <div className="min-h-screen flex flex-col items-center justify-center bg-gray-100 text-center">
        <h1 className="text-5xl font-bold text-blue-600">Welcome to My Page</h1>
        <p className="mt-4 text-lg text-gray-700">
          Still Working Here.
        </p>
        <div className="mt-6 flex space-x-4">
          <Link
            to="/about"
            className="flex items-center gap-2 px-6 py-3 bg-blue-500 text-white rounded-lg shadow-md hover:bg-blue-600 transition"
          >
            Learn More <ArrowRight size={18} />
          </Link>
          <Link
            to="/contact"
            className="flex items-center gap-2 px-6 py-3 bg-gray-500 text-white rounded-lg shadow-md hover:bg-gray-600 transition"
          >
            <Info size={18} /> Info
          </Link>
        </div>
      </div>
    </>
  );
};

export default Home;

Example Navbar.tsx (Component):

import { Link } from "react-router-dom";
import { Home, Info, BookOpen } from "lucide-react";

const Navbar = () => (
  <nav className="bg-white shadow-md p-4">
    <ul className="flex space-x-6 items-center">
      <li>
        <Link to="/" className="flex items-center gap-1 hover:text-blue-600 transition">
          <Home size={18} /> Home
        </Link>
      </li>
      <li>
        <Link to="/about" className="flex items-center gap-1 hover:text-blue-600 transition">
          <Info size={18} /> About
        </Link>
      </li>
      <li>
        <Link to="/docs" className="flex items-center gap-1 hover:text-blue-600 transition">
          <BookOpen size={18} /> Docs
        </Link>
      </li>
    </ul>
  </nav>
);

export default Navbar;

Setting Up Routes with React Router

import { BrowserRouter as Router, Routes, Route } from "react-router-dom";
import Navbar from "./components/Navbar";
import Home from "./pages/Home";

const App = () => (
  <Router>
    <Navbar />
    <Routes>
      <Route path="/" element={<Home />} />
    </Routes>
  </Router>
);

export default App;

Starting the Development Server

npm run dev

Access http://localhost:5173.
