What is the JavaScript library for working with APIs of popular services (OAuth2, Social API, etc)?

Question

JavaScript

Hello %username%. I want to ask the wisest community if there are js libraries that implement the API of popular services such as G+, Facebook, Twitter, Vkontakte? A giant plus if they are libraries for Backbonejs or Angularjs.
In the process of googling, I came across such things:
appengine-oauth-angular (by the way, appengine is also used in the project)
angular-oauth
etc...
In general, what I want from a library:
1. abstractions over API function calls
For example, it doesn’t matter through which social network the user logged in, I want to have one interface for all social networks. For example, a function call:
var friends = user.friends()
Always gave me back what I expect. I would like to abstract from a specific social network, and use the "social network API" interface, and not, for example, "Vkontakte API".
2. It is possible to quickly and easily expand the library with missing APIs.
I understand that you can take it and write it yourself, but unfortunately, the deadlines :-(
What tools do you use?
UPD.
I googled such a hello.js tool . This is already something close in spirit!

Answer 1

I don’t understand why it’s so bad to google what I want. Oh well, I'll close the issue.
PS Googled another thing oauth.io

Answer 2

passport.js
but it's more for a node as far as I remember
