Hey, what’s up, football fans! If you’re a Liverpool supporter like me, you know that the best things come from Anfield.
But did you know that React can also provide some serious value?
Here, we’re going to talk about React server-side rendering and how it can help you take your web app game to the next level.
React Server-Side Rendering
First, let’s talk about what server-side rendering (SSR) is.
In a nutshell, it means rendering your web app on the server and sending the fully-formed HTML to the client, rather than sending just the JavaScript and having the client render the app in the browser.
This can improve your app’s performance, especially on slow devices or poor network connections.
Now, let’s talk about how to implement SSR in a React app.
Here are the basic steps:
Set up a server
You’ll need to create a server that can render your app on the server–side.
There are several options for this, but one popular choice is Node.js with Express.
Set up your React app
You’ll need to set up your React app to work with SSR.
This involves using a special component called “ReactDOMServer” to render your app on the server.
Handle requests
You’ll need to handle incoming requests on the server and render the appropriate response.
This involves rendering the React app with the requested URL and sending the fully–formed HTML back to the client.
Here’s an example of how to implement SSR in a React app:
import React from 'react';
import ReactDOMServer from 'react-dom/server';
import App from './App';
const express = require('express');
const app = express();
// Define a route for the root URL
app.get('/', (req, res) => {
// Render the App component to HTML using ReactDOMServer's renderToString method
const html = ReactDOMServer.renderToString(<App />);
// Send an HTML response that includes the rendered App component, along with a script tag for the client-side bundle
res.send(`
<!DOCTYPE html>
<html>
<head>
<title>Liverpool FC SSR App</title>
</head>
<body>
<div id="root">${html}</div>
<script src="/bundle.js"></script>
</body>
</html>
`);
});
// Start the server and listen on port 3000
app.listen(3000, () => {
console.log('App listening on port 3000');
});
In this example, we’re rendering our React app using “ReactDOMServer.renderToString“, which renders the app to a string of HTML.
We’re then sending this HTML back to the client in a basic HTML template.
Note that we’re also including a script tag for a client-side JavaScript bundle, which will be used to hydrate the app on the client-side.
Conclusion
So, there you have it! With just a few steps, you can implement server-side rendering in your React app and improve your app’s performance.
And if you’re a Liverpool fan, you can enjoy faster loading times for your app, just like Liverpool’s speedy forwards on the pitch.
