react seo

As a web developer, you may have noticed that search engines like Google have a hard time crawling and indexing the content of your React single-page applications (SPAs). This can be a problem if you want your app to be SEO-friendly and rank well in search results. One solution to this problem is to use server-side rendering (SSR).

With SSR, the initial HTML for your app is rendered on the server and then served to the client, rather than being rendered entirely on the client using JavaScript. This allows search engines to crawl and index the content of your app, even if it is a SPA.

Here\’s how you can set up SSR for your React app:

  • First, install the package you\’ll use to render the initial HTML on the server. For example, you can use preact-render-to-string or react-dom/server.

npm install preact-render-to-string

2. Next, create a route handler on your server that will be responsible for rendering the initial HTML for your app. This route handler should import the rendering function and use it to render the initial HTML for your app. Here\’s an example of how you might do this using preact-render-to-string:

import { h, renderToString } from \'preact-render-to-string\';
import App from \'./App\';

const handleRender = (req, res) => {
  const html = renderToString(<App />);
  res.send(html);
};

3. You can then set up your server to use this route handler for requests to your app. For example, if you\’re using Express, you can do this as follows:

import express from \'express\';
const app = express();

app.get(\'*\', handleRender);

app.listen(3000, () => {
  console.log(\'Server is listening on port 3000\');
});

  • Make sure to enable caching on your server so that the initial HTML is served from the cache whenever possible. This will help reduce the load on your server and improve the performance of your app.
  • When the client receives the initial HTML, it should hydrate the static content by mounting the React app on top of it. This allows the app to preserve its state and continue rendering as a SPA.

By following these steps, you can set up SSR for your React app and improve its SEO and performance. You can also use tools like prerender-spa-plugin or react-snap to pre-render your app and generate static HTML files that can be served directly to the client.
