Goldengate intends to be a replacement for Cordova/PhoneGap on iOS and Mac. Why? Cordova is designed with the assumption that you don’t want to know anything about native app development — and that is just plain annoing to me.


  • built with WKWebView, Swift & CoffeeScript
  • works on iOS and Mac
  • very lightweight (no support for legacy systems, etc.)
  • asynchronous calls using Promises, not callbacks
  • (WIP) nice syntax for calling plugins from JS: Goldengate.PluginName.method(args)
  • (WIP) a compatibility layer for importing existing Cordova plugins


At the moment, Goldengate is (and can be) only a proof of concept, because WKWebView can’t load web pages from the app bundle. This has been fixed on the upstream repo, but it’s possible that the necessary API won’t be added until OS X 10.11 / iOS 9.

Idea to try: according to this tweet, WKWebView can load local files from /tmp. Can we try making a tmp directory at launch and copying the needed files there?


Xcode project requires Xcode 6.1 running on OS X 10.10. The web component requires CoffeeScript (accessible globally via coffee command).

You need Pow to serve the web page locally (as noted above, WKWebView can’t load from app bundle). Point ~/.pow/goldengate to the GoldengateJS directory. Alternatively, if you’re using a different web server, edit the URL in AppDelegate.swift

If you’re working on the web component, be sure to run the watcher script (./watch from GoldengateJS) beforehand. It will listen to changes in CoffeeScript files and compile them.


If this sounds like something you’d want for yourself, please feel free to contribute and open a pull request. There’s a bunch of open issues you can choose from. And if you want to talk about the project some more, email me
