How to do Facebook Open Graph friendly meta tags with client-side template engines like AngularJS, Mustache, Handlebars

Question

According to my testing, Facebook\'s crawlers do not render client-side templates like a browser.

I want to avoid a webserver and building HTML files for Open Graph

Answer 1

Use the ?_escaped_fragment_ method along with a prerender service. Facebook will respect the same crawlable Ajax specification as Google. Please see https://developers.google.com/webmasters/ajax-crawling/docs/specification
