Answer 1

see my blog at http://authguidance.com

NodeJS + tutorial based - with code samples and write ups

And you can send me questions

Very detailed though - might make your brain hurt!!

Answer 2

You can use passportjs to provide you the oauth 2.0 support. You will need googleClientID and googleClientSecret. Which you can get by registering your application to google developers site

var GoogleStrategy = require('passport-google-oauth20').Strategy;

 const mongoose = require('mongoose');
 const keys = require('./keys');
 const User = mongoose.model('users');

module.exports = function(passport){
  passport.use(
new GoogleStrategy({
  clientID:keys.googleClientID,
  clientSecret:keys.googleClientSecret,
  callbackURL:'/auth/google/callback',
  proxy:true
},(accessToken,refreshToken,profile,done)=>{
//     console.log(accessToken);
//     console.log(profile);
  const image = profile.photos[0].value.substring(0,profile.photos[0].value.indexOf('?'));

  const newUser = {
    googleID:profile.id,
    firstName:profile.name.givenName,
    lastName :profile.name.familyName,
    email:profile.emails[0].value,
    image:image
  }

  //Check for existing user
  User.findOne({
    googleID:profile.id
  }).then(user=>{
    if(user){
      //Return user
      done(null,user);
    }
    else{
      //Create a new user
      new User(newUser)
      .save()
      .then(user=> done(null,user)); 
    }
  })
 })
)

passport.serializeUser(function(user, done) {
done(null, user.id);
});

passport.deserializeUser(function(id, done) {
 User.findById(id, function(err, user) {
   done(err, user);
     });
   });
 }

Dependencies = "passport": "^0.4.0", "passport-google-oauth": "^1.0.0"

This will redirect req. to above code..
const express = require('express');
const router = express.Router();
const passport = require('passport');

 router.get('/google',passport.authenticate('google',{scope:
      ['profile','email']}));

 router.get('/google/callback', 
   passport.authenticate('google', { failureRedirect: '/' }),
   function(req, res) {
   // Successful authentication, redirect home.
   res.redirect('/dashboard');
  });

   router.get('/verify',(req,res)=>{
   if(req.user){
   console.log(req.user);
  }else{
   console.log('Not Auth');
  }
});

router.get('/logout',(req,res)=>{
   req.logout();
   res.redirect('/');
 })
 module.exports = router;
