prerender-node

Express middleware for serving prerendered JavaScript-rendered pages to crawlers (Google, Facebook, Twitter, Bing) to improve SEO for Angular, React, Vue, and other JS frameworks. Current stable version: 3.8.3. Released as needed, maintained actively. Key differentiator: integrates with Prerender.io cloud service or self-hosted prerender server, supports whitelist/blacklist, beforeRender/afterRender hooks. Compared to alternatives like puppeteer-based solutions, it offloads rendering to an external service, reducing server load.
