I work on a medium sized angular webapp (10K+ LOCs), and have spoken to large teams in organizations that build their applications using angular that have 100K+ LOCs, but have not seen an open source application on this scale. Some problem/solutions I've seen:

* Programmers split work by taking ownership on modules, treat modules by other programmers as black boxes, and use bower with a company hosted server to manage dependencies.

* Some programmers I've spoken to have tried using requirejs or bower to manage dependencies, but most I've talked to dislike the overhead this causes.

* Large apps dynamically load routes on-demand. The core angularjs framework is not built for this, but numerous hacks have been put forward by the community to handle dynamic loading of javascript modules, and honestly, it's not that bad. Thankfully, built-in support for dynamic loading of components is on the angular roadmap.

* Personally, I annotate my files such that, for any dynamically injected reference, the reader can directly navigate to the source file. Google closure syntax, browserify, and requirejs also provide this support.

I hope those anecdotes help.
