// 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 GitHub profile is serialized
// and deserialized.
passport.serializeUser(function(user, done) {
done(null, user);
});
passport.deserializeUser(function(obj, done) {
done(null, obj);
});
// Use the GitHubStrategy within Passport.
// Strategies in Passport require a `verify` function, which accept
// credentials (in this case, an accessToken, refreshToken, and GitHub
// profile), and invoke a callback with a user object.

// represent the logged-in user. In a typical application, you would want
// to associate the GitHub account with a user record in your database,
// and return that user instead.
