I've been searching GitHub and blog posts for any open source actual single page applications (not frameworks, generators, etc..) and have come up with some good resources but nothing that exactly fits my need.

There is a backbone example [1] but that's only a ToDo list. Pretty much all of the stuff I work on is more complex than that (I'm just a jr dev but the example is so contained), so these examples don't give me a good way of checking my work and understanding.

I understand people use ToDo as their demo because it allows for easy cross-comparison but for digging in it really doesn't help much. One object, tracking its few properties, and keeping a list will be maintainable and extensible just because of how small the codebase is.

So if anyone knows of some medium sized to large SPAs on GitHub that would be great. If there aren't any, if anyone wants to collaborate and build one together along with a series of blog posts or text files we throw in the directories along with our reasoning I'm down.
