// Passport session setup.
//   To support persistent login sessions, Passport needs to be able to
//   serialize users into and deserialize users out of the session.  Typically,
//   this will be as simple as storing the user ID when serializing, and finding
//   the user by ID when deserializing.  However, since this example does not
//   have a database of user records, the complete Trakt profile is serialized
//   and deserialized.
passport.serializeUser(function(user, done) {
  done(null, user);
});

passport.deserializeUser(function(obj, done) {
  done(null, obj);
});

// Use the TraktStrategy within Passport.
//   Strategies in Passport require a `verify` function, which accept
//   credentials (in this case, an accessToken, refreshToken, and Trakt
//   profile), and invoke a callback with a user object.
passport.use(new TraktStrategy({
    clientID: TRAKT_CLIENT_ID,
    clientSecret: TRAKT_CLIENT_SECRET,
    callbackURL: 'https://127.0.0.1:3000/auth/trakt/callback'

    // asynchronous verification, for effect...
    process.nextTick(function () {
      console.log(params);
      // To keep the example simple, the user's Trakt profile is returned to
      // represent the logged-in user.  In a typical application, you would want
      // to associate the Trakt account with a user record in your database,
      // and return that user instead.
      return done(null, profile);
    });

// Simple route middleware to ensure user is authenticated.
//   Use this route middleware on any resource that needs to be protected.  If
//   the request is authenticated (typically via a persistent login session),
//   the request will proceed.  Otherwise, the user will be redirected to the
//   login page.

// GET /auth/trakt
//   Use passport.authenticate() as route middleware to authenticate the

//   the user to trakt.tv.  After authorization, Trakt will redirect the user
//   back to this application at /auth/trakt/callback

// GET /auth/trakt/callback
//   Use passport.authenticate() as route middleware to authenticate the
//   request.  If authentication fails, the user will be redirected back to the
//   login page.  Otherwise, the primary route function function will be called,
//   which, in this example, will redirect the user to the home page.
