Brian said: I'm not sure Roll20 is using Node at all. I know it uses Ruby. And, obviously, a lot of JavaScript on the site itself (with jQuery), but I'm not certain on Node. Why do you need to know Node version, when your API script has no access to any Node code, anyway? The API server runs Node, I believe. I'm not sure what other option they'd be using to execute JS serverside. Actually, I don't *really* care about the node version so much as the V8 version. I'm unit testing my code, and I want the environment of the tests to mirror the deployment environment as closely as possible. I'd like the CI environment to explode in a shower of sparks if I accidentally use a language feature that is not available on the node version that runs the API.
