react error page 404 tailwind

3 min read 01-10-2024

When developing a web application, creating user-friendly error pages is essential for maintaining a good user experience. A 404 error page indicates that the requested page could not be found. In this article, we will explore how to create a visually appealing 404 error page in a React application using Tailwind CSS.

Why is a Custom 404 Error Page Important?

Custom 404 error pages serve several purposes:

User Guidance: It informs users that the page they are looking for doesn't exist and provides alternative navigation options.
Branding: A well-designed error page can enhance your brand's image and keep users engaged.
SEO Benefits: A custom error page can be optimized for search engines, potentially retaining traffic by guiding users to relevant content instead of leaving them frustrated.

Setting Up Your React Environment

Before we dive into creating a 404 error page, ensure that you have a React application set up with Tailwind CSS. If you haven't set it up yet, follow these steps:

Create a new React application using Create React App:
```
npx create-react-app my-app
cd my-app
```

Install Tailwind CSS:

npm install tailwindcss postcss autoprefixer

Initialize Tailwind CSS:
```
npx tailwindcss init -p
```
Configure your tailwind.config.js file and include Tailwind in your CSS files.

Creating the 404 Error Page Component

Now that we have our environment set up, we can create the 404 error page. Create a new component in your src folder called NotFound.js:

// src/NotFound.js
import React from 'react';

const NotFound = () => {
    return (
        <div className="flex items-center justify-center min-h-screen bg-gray-100">
            <div className="text-center">
                <h1 className="text-6xl font-bold text-red-600">404</h1>
                <h2 className="mt-4 text-2xl font-semibold">Oops! Page Not Found</h2>
                <p className="mt-2 text-gray-600">
                    The page you're looking for doesn't seem to exist.
                </p>
                <a href="/" className="mt-4 inline-block px-6 py-2 text-white bg-blue-600 rounded hover:bg-blue-700">
                    Go Home
                </a>
            </div>
        </div>
    );
};

export default NotFound;

Explanation of the Code

Container: The entire page is wrapped in a flex container which centers the content both vertically and horizontally.
Typography: The use of Tailwind’s typography classes (text-6xl, text-2xl, etc.) makes it easy to manage the font sizes and styles.
Button: The call-to-action button styled using Tailwind’s utility classes provides a straightforward navigation option back to the homepage.

Setting Up Routing

To display our custom 404 error page, we need to set up routing in our React application. Assuming you're using react-router-dom, you can define your routes in App.js:

// src/App.js
import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import NotFound from './NotFound';
import Home from './Home'; // Example of a Home component

const App = () => {
    return (
        <Router>
            <Switch>
                <Route exact path="/" component={Home} />
                {/* Other routes can go here */}
                <Route component={NotFound} /> {/* This will catch all unknown routes */}
            </Switch>
        </Router>
    );
};

export default App;

How It Works

Switch: The Switch component will render the first matching Route. If no route matches, it will render the NotFound component.
Order of Routes: Ensure the NotFound route is defined last, so it catches all unmatched paths.
