Steps to Setup the Application

Step 1: Create a reactJS application by using this command

npx create-react-app myapp

Step 2: Navigate to project directory

cd myapp

Step 3: Install the necessary packages/libraries in your project using the following commands.

Example: Implementation to show the explanation for static handler.

JavaScript

// App.js

import React from 'react';
import StaticPage from './StaticPage';
import {
    BrowserRouter as Router,
    Routes,
    Route
} from 'react-router-dom';

const Home = () => (
    <div>
        <h1>Home Page</h1>
        <p>Welcome to the Home Page!</p>
    </div>
);

const Header = () => (
    <div>
        <h1>Header Page</h1>
        <p>Welcome to the w3wiki!</p>
    </div>
);

const App = () => {
    return (
        <Router>
            <div>
                <Header />
                <Routes>
                    <Route path="/"
                           element={<Home />} />
                    <Route path="/static"
                           element={<StaticPage />} />
                </Routes>
            </div>
        </Router>
    );
};

export default App;

JavaScript

// StaticPage.js

import React from 'react';

const StaticPage = () => {
    return (
        <div>
            <h1>This is a Static Page</h1>
            <p>
                This content is
                statically rendered.
            </p>
        </div>
    );
};

export default StaticPage;

Explanation: In this example, the <Header /> component is like a fixed header that appears on every page. It’s our “static handler” for the header content. Using React Router’s <Routes> component, we define routes for different pages. For the root URL (“/”), we render the <Home /> component, and for “/static”, we render <StaticPage />, which is another static page. So, <Header /> stays the same across all pages, while <StaticPage /> shows statically rendered content.

Step to Run Application: Run the application using the following command from the root directory of the project

npm start

Output: Your project will be shown in the URL http://localhost:3000/

What is StaticHandler in React Router

React Router is a popular library in the React ecosystem that enables routing in single-page applications (SPAs). It allows developers to define navigation and rendering rules based on the URL of the application. One of the essential components of React Router is the StaticHandler, which plays a crucial role in handling static routes within your application. In this article, we will delve into what the StaticHandler is, how it works, and its significance in React Router applications.
