I do not like such big frameworks… because they are made for webapps where backend is really hard connected to the frontend in most cases (like kraken js oder meteor)…
in your case i would learn nodejs and after that express and node… that is enough to build own and lightweight APIs.
Learn the technologies before asking for using frameworks ;).
Maybe you are coming to the conclusion that this is the ideal solution for that… but please take a deeper look in plain nodejs and mongodb… build a littel api with expressjs.
After that try to understand authorisation methods… especially oauth with json web tokens end so on.
In other cases we get “experts” like Javascripter, who have used jQuery the whole time and thinking they can program javascript.
i will create a repo on my github account in the next day, where i hold a new version of my own base nodejs+express+mongo API… if i am not forgetting you… i can share the link
