Understanding StaticRouterProvider:

Type Declaration with Syntax:

StaticRouterProvider is typically imported from react-router-dom.

Syntax:

import { StaticRouterProvider } from 'react-router-dom';

Context:

StaticRouterProvider operates within the context of server-side rendering in React applications.
It facilitates the rendering of React components on the server and the transmission of HTML to the client.

Router Integration:

As part of React Router, StaticRouterProvider seamlessly integrates with routing logic on the server.
It ensures that routing functionalities remain consistent across client and server environments.

Hydration:

StaticRouterProvider plays a crucial role in hydration, where the server-rendered HTML is converted into a fully interactive React application on the client-side.
It ensures that client-side navigation and interactions align with the server-rendered content.

Features of StaticRouterProvider:

StaticRouterProvider offers several key features essential for server-side rendering:

Seamless integration with React Router for handling routing logic on the server.
Facilitation of rendering React components on the server and transmitting HTML to the client.
Ensuring consistent navigation behavior across client and server environments.
Support for passing routing context to components for enhanced customization.
Compatibility with various server-side rendering frameworks and environments.

Steps to implement StaticRouterProvider:

Step 1: Create a new React JS project using the following command

npx create-react-app <<Project_Name>>

Step 2: Change to the project directory.

cd <<Project_Name>>

The updated dependencies in package.json will look like this:

"dependencies": {
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-router-dom": "^6.22.3",
    "react-scripts": "5.0.1",
    "web-vitals": "^2.1.4"
  },

Example of StaticRouterProvider

Code Example: This example demonstrates how StaticRouterProvider is used on the server side to render React components dynamically based on the requested URL.

JavaScript

const express = require('express');
const React = require('react');
const ReactDOMServer = require('react-dom/server');
const { StaticRouter,
    BrowserRouter,
    Route,
    Switch } = require('react-router-dom');

const server = express();

server.use(express.static('build'));

const Home = () => <div>Home Page</div>;
const About = () => <div>About Page</div>;

server.get('*', (req, res) => {
    const context = {};
    const serverApp = ReactDOMServer.renderToString(
        <StaticRouter location={req.url} context={context}>
            <BrowserRouter>
                <Switch>
                    <Route path="/" exact component={Home} />
                    <Route path="/about" component={About} />
                </Switch>
            </BrowserRouter>
        </StaticRouter>
    );

    if (context.url) {
        res.redirect(context.url);
    } else {
        res.status(200).send(`
      <!DOCTYPE html>
      <html>
        <head>
          <title>React SSR Example</title>
        </head>
        <body>
          <div id="root">${serverApp}</div>
          <script src="/bundle.js"></script>
        </body>
      </html>
    `);
    }
});

server.listen(8000, () => {
    console.log('Server is listening on port 8000');
});

Conclusion:

StaticRouterProvider plays a pivotal role in React Router, particularly for applications requiring server-side rendering. By understanding its features and practical implementation, developers can leverage StaticRouterProvider to enhance the performance and user experience of their React applications. Whether building a simple website or a complex web application, StaticRouterProvider remains indispensable for achieving server-side rendering with React Router.
