About

A library that simplifies the exposure of data through REST interfaces in a secure, scope dependent way. Basically transforms internal data into whatever a client of your API has the right to see.

Where does it fit in?

In general this should be the last step in a request pipeline before rendering objects to the client. An example would be

      @apiFacade.mapRoot 'User', item, {baseUrl: @baseUrl, scopes:req.scopes}, (err,jsonObj) =>
          res.json jsonObj

where apiFacade is the instantiated apiFacade object (which contains all the schema definitions)

Features

  • Agnostic towards the data model
  • Can resolve relationships and extend objects (Think instagram adding user data when making an API request.)
  • Fast enough. There is a lot of room for optimizations, but it is fast enough for our purposes.
  • Resolvers are extensible
  • Used in real projects (with 30K+ lines of node code).
  • Supports scopes

More

Resonable documentation will be written when I have a bit more time.

Release Notes

0.2.3

  • Fixed some nasty bugs when using it with mongoose. The gist is: We store keys to resolve as string now, and if an object has a toObject function, we invoke that. Otherwise libs that override toJSON mess with our resolve.
  • Exposed resolve at the top level to support 2 phase resolve.

    0.2.2

  • Added support for fn mapping. No docs or tests yet, but works like this:
    mappings:
      url: 
        fn: (self,options) -> "#{options.baseUrl}/products/#{self._id}"

Using self for clarity. Thought it might be easier then mapping this.

0.2.1

  • Added support for default scope if none is present. E.g. define a default scope, which is used if options.scopes is null or contains nothing.

    0.2.0

  • First version

Internal Stuff

Contributing to node-api-facade

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
  • Fork the project
  • Start a feature/bugfix branch
  • Commit and push until you are happy with your contribution
  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
  • Please try not to mess with the package.json, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
