...Rendertron renders requested pages using Headless Chrome, auto-detecting when your PWA has completed loading and serializes the response back to the original request. To use Rendertron, your application configures middleware to determine whether to proxy a request to Rendertron. Rendertron is compatible with all client side technologies, including web components. It is not designed to be used as a production endpoint. You can use it, but there are no uptime guarantees. Once you have the service up and running, you'll need to implement the differential serving layer. This checks the user agent to determine whether prerendering is required.
