It looks like you don't name require('./passport.js')(passport)
(or whatever). you are not setting up a passport. My guess is perhaps further backed up by the fact that if you include this code from passport.js
, you will see SyntaxError: Unexpected token ;
, because by removing parameters and unnecessary things, this is what you define:
passport.use(new GoogleStrategy({}, passport.serializeUser(function(user, done){});
passport.deserializeUser(function(id, done) { });
function(token, refreshToken, profile, done) { });
If you are going to follow this tutorial, you should take a look at the first part, which defines the basic application. In admin.js
add require('./passport.js')(passport)
after the linerequire('passport')
