prerender-node

Express middleware that prerenders JavaScript-rendered pages on the fly so search crawlers get complete HTML. Google, Facebook, Twitter and Bing all try to view your pages, yet Google is the only crawler that executes a meaningful amount of JavaScript. The middleware intercepts requests from crawlers and serves them the full rendered page, which avoids indexation problems for pages built with Angular, React, Vue or other frameworks. Options let you whitelist or blacklist paths, run code before or after render, set the protocol and host, forward headers and cache results, and you can point it at your own prerender service. A GitHub Actions workflow tests and publishes releases. It is described as a good fit for Angular SEO, React SEO and Vue SEO.
