The Ruby Racer: Under the Hood
summary
A gem embeds the V8 interpreter into the Ruby process so Ruby code evaluates JavaScript, gets direct JS object references and invokes JS functions, and JavaScript can call Ruby methods or instantiate Ruby classes. Teams run unit tests headless using jsdom and node html parser on CI, share Handlebars/Mustache templates and validation/business logic between client and server, and compile Less via the gem; garbage collection and safe-eval sandboxes are the hard engineering problems but the integration works and yields real performance and reuse benefits.
