How Can I Integrate Prerender With My React/Angular/Vue Application?

Prerender improves SEO for SPAs by integrating it with a CDN or web server (like Nginx, Apache, or Node.js), ensuring proper functionality and caching for better performance.

Overview

Single Page Applications (SPAs) built with client-side JavaScript frameworks (such as React, Angular, and Vue) often face challenges when it comes to search engine optimization (SEO). These frameworks load content dynamically after the initial page request, making it difficult for search engines to index the content properly.

Prerender.io provides an excellent solution to this problem by rendering a fully loaded page for search engine crawlers. However, because SPAs don't natively detect or redirect requests to Prerender, it's important to integrate Prerender into your infrastructure to ensure proper functionality.

 

Why Integrate Prerender?

Prerender.io renders JavaScript-heavy SPAs on the server side and serves search engines fully-rendered HTML pages instead of just static, unrendered JavaScript. Since SPAs don’t inherently provide search engines with crawable HTML content, integrating Prerender helps deliver a page that is fully indexable by search engines like Google, Bing, and others.

The key advantage is that Prerender ensures that the page is indexed and its content is visible to search engines—just like a static website—improving SEO, especially for dynamic content that changes after page load.

 

Integration Strategies

To achieve optimal performance with Prerender, integrate it as close to the user as possible. The most effective places for integration are at the Content Delivery Network (CDN) or Reverse Proxy level. If this is not possible, Prerender can also be integrated into your web server.

 

  1. CDN integration:

  2. Web server integration:

    1. Nginx integration

      We have three available Nginx integrations for the use cases of Nginx. 

    2. Apache webserver

    3. Node.js with Express: for Node.js applications using Express, you can use the prerender-node middleware:

      const prerenderMiddleware = require('prerender-node');
      app.use(prerenderMiddleware.set('prerenderToken', 'YOUR_TOKEN'));

 

 

Verify Your Installation

After integration, it’s important to verify that everything is working as expected. We’ve provided an easy-to-follow guide to help you test your setup and confirm that Prerender is functioning properly.
