I am going to respond to each point
- Nailed it on this comment. I have been trying to figure out something that "makes sense" in terms of file structure and even code organization. So far, it hasn't been too much of a hindrance, but it I know the more code I write, the more unwieldy things will probably get.
- This is something that I have been very aware of and the way I have been handling it is limiting the number of controllers in general so I do not introduce new scopes. For the most part, all of the pages do not need to introduce new scopes and the data should be consistent across the pages anyways, so this hasn't been too much of an issue (yet).
-I haven't had this issue yet, but I haven't sufficiently tested this. From some initial testing, the memory footprint has been pretty light, but I need to do a lot more on this end once I have completed more of the app.
-State management hasn't been too tricky because there's only two states that I really care about: whether a user has logged in or if they are logged off. This part I have been addressing by loading JSON for contact information into the page to both limit the amount of AJAX requests and to enforce routing. Fortunately, this state is also managed by HTTPS Cookies so this is handled server side as well.
-I don't know how to validate or dispute this, but it looks like loading the minified scripts from CDNJS for both Angular and React were the same filesize. In any case, I have been using A LOT of what comes with Angular out of the box and have been using the UI Router library as well as the ng-Sanitize library for what I need. Haven't had too many issues with this.
