So, theres another SO question for this: Which files to keep under source control for google-chrome-app?
And we have an open github issue to figure this out and provide guidance: https://github.com/MobileChromeApps/mobile-chrome-apps/issues/85
And we have some existing users of cca
who have already devised their own .gitignore
: https://github.com/plaxdan/react-topcoat-demo
The truth is, the answer isn't set in stone, and will likely change in the future. We are trying to help you figure out the answer for yourself, and are hoping to get feedback about what worked best for you.
