This is a node server that uses phantomjs to render a javascript-rendered page as HTML. It should be used in conjunction with prerender_rails or prerender-node middleware to serve the rendered HTML to crawlers for SEO. You don't have to run this service on your own since I have it deployed on Heroku already. Get started in two lines of code using Rails or Node
It is also meant to be proxied through your server so that any relative links to things like CSS will work.
It is currently deployed at http://prerender.herokuapp.com, or you can deploy your own.
$ git clone https://github.com/collectiveip/prerender.git
$ heroku create
$ git push heroku master
$ npm install
$ node index.js
// also supports heroku style invokation using foreman
$ foreman start
This is a simple service that only takes a url and returns the rendered HTML (with all script tags removed).
Note: you should proxy the request through your server so that relative links to CSS still work (see prerender_rails or prerender-node for an example)
GET http://prerender.herokuapp.com/https://google.com
GET http://prerender.herokuapp.com/https://google.com/search?q=angular
We remove script tags because we don't want any framework specific routing/rendering to happen on the rendered HTML once it's executed by the crawler. The crawlers may not execute javascript, but we'd rather be safe than have something get screwed up.
For example, if you rendered the HTML of an angular page but left the angular scripts in there, your browser would try to execute the angular routing and rendering on a page that no longer has any angular bindings.
