Derby.js Authentication

Provides authentication middleware (using Passport) for use in your Derby projects.

###Step 1 Initialize derby-auth above expressApp.use() directives.

var
    auth = require('derby-auth'),

    // Pass in actual Passport Strategy objects as well as their configurations (see http://passportjs.org/guide/facebook/)
    // Note: this means you'd need "passport-facebook" in your package.json file
    strategies = {
      facebook: {
        strategy: require('passport-facebook').Strategy,
        conf: { clientID: process.env.FACEBOOK_KEY, clientSecret: process.env.FACEBOOK_SECRET }
    },

    // Pass in options. Domain defaults to localhost:3000, but consider it required
    // (It's a Passport technicality, if anyone has suggestions for determining domain on run-time, please message me)
    options = {
        domain: (process.env.NODE_ENV==='production' ? "http://my.com" : "http://localhost:3000" )
    }

// Init. {expressApp} sets up routes, {store} sets up accessControl & queries
auth.init(expressApp, store, strategies, options);

###Step 2 Use derby-auth's middleware

.use(store.modelMiddleware())
// derby-auth.middleware is inserted after modelMiddleware and before the app router to pass server accessible data to a model
.use(auth.middleware())
.use(app.router())

###Step 3 Use derby-auth's routes

auth.routes();

See the example for more details, as well as login / registration forms, sign-in buttons, etc.

Why not EveryAuth?

This project was originally implemented with Everyauth (see branch), but had some issues:

1. Every provider had to be implemented individually in code. Passport has an abstraction layer, which is what allows us to pass in Strategy + conf objects in server/index.js for every provider we want enabled.
2. Password authentication posed technical difficulties. See the Google Group discussion
