[web2py] Re: Server-side AngularJS execution?
I'd not recommend any of the mvc javascript frameworks if you're interested in any SEO consistent results. Support for executing javascript by crawlers is largely missing and there is no documented way to tell them to crawl and execute specific fragments. If you're positive about implementing it, then you need to render your pages as static not using angularjs and provide only those links in your sitemap. There is no way to let web2py handle the angularjs logic because there are no python adapters for it.

So I was thinking if there was some way to execute the AngularJS as static files; for search-spiders and non-javascript enabled browsers; but when they have JavaScript support execute it client-side. It would also save the trouble of implementing each view twice; once in web2py views the other in AngularJS MVC. Would this be possible? If not, how would you recommend I go about doing this?

You might be able to use a headless browser on the server to execute the Javascript to generate the HTML. The Meteor frameworkhttp://www.meteor.com/blog/2012/08/08/search-engine-optimizationuses PhantomJS http://phantomjs.org/ for this purpose. There is also Zombie.jshttp://zombie.labnotes.org/, which has a Python driver https://github.com/ryanpetrello/python-zombie, and the Python based Spynner https://github.com/makinacorpus/spynner.

Re: [web2py] Re: Server-side AngularJS execution?
Thanks Anthony, using Spynner now: import spynner if __name__=='__main__': url = http://angular.github.com/angular-phonecat/step-10/app/#/phones; browser = spynner.Browser() browser.create_webview(True) browser.load(url, load_timeout=60) print browser._get_html() # ^ Can pipe this to a file, POST it to my server or return it as a string browser.close() Doubt I'll find a PaaS to run it though, so might need to run a server on my desktop that gets pinged by my app on the cloud; then provides the new HTML. Do you think any of your others would run on a PaaS like Heroku or OpenShift?
