Spray Prerender

Are you using backbone, angular, emberjs, etc, but you're unsure about the SEO implications?

Use this Spray directive that prerenders a javascript-rendered page using an external service and returns the HTML to the search engine crawler for SEO.

Note: If you are using a # in your urls, make sure to change it to #!. View Google's ajax crawling protocol

Note: Prerender service will make a request to your server to render the HTML.

1- Add this dependency on your project:

    "com.github.jarlakxen" %% "spray-prerender" % "1.1"

2- Add this line to your code

    implicit val prerenderConfig = routePrerender("10.254.169.132:9290", actorRefFactory)


     get {
      prerender(prerenderConfig) {
        mustache("/index")
      }
    }

Note: You need to extends or import PrerenderDirectives. Note: The first parameter of routePrerender is the ip and port of the Prerender server.

How it works

1. Check to make sure we should show a prerendered page
   1. Check if the request is from a crawler (agent string)
   2. Check to make sure we aren't requesting a resource (js, css, etc...)
2. Make a GET request to the prerender service (phantomjs server) for the page's prerendered HTML
3. Return that HTML to the crawler
