justcoded/goprerender repository overview

⁠Golang Prerender

GO Prerender is a dockerized server app written in Golang that uses Headless Chrome to render HTML and JS files out of any web page. The Prerender server listens for an HTTP request, takes the URL and loads it in Headless Chrome, waits for the page to finish loading by waiting for the network to be idle, and then returns your content.

⁠In memory cache

Caches pages in memory using gopreprender-storage image container.
