What I tried to do:
mongoose.connect(...) code is loading except this is my code where I tried to comment out: useFindAndModify: true
db.js
const mongoose = require('mongoose')
const connectDB = async () => {
try {
const conn = await mongoose.connect(process.env.MONGO_URI, {
useNewUrlParser: true,
useUnifiedTopology: true,
// useFindAndModify: true
})
console.log(`MongoDB Connected: ${conn.connection.host}`)
} catch(err) {
console.error(err)
process.exit(1)
}
}
module.exports = connectDB
auth.js
const express = require('express')
const passport = require('passport')
const router = express.Router()
// #desc Auth with Google
// #route GET /auth/google
router.get('/google', passport.authenticate('google', { scope: ['profile'] }))
// #desc Google auth callback
// #route GET /auth/google/callback
router.get('/google/callback', passport.authenticate('google', { failureRedirect: '/' }),
(req, res) => {
res.redirect('/dashboard')
})
module.exports = router
passport.js
const GoogleStrategy = require('passport-google-oauth20').Strategy
const mongoose = require('mongoose')
const User = require('../models/User')
module.exports = function (passport) {
passport.use(new GoogleStrategy({
clientID: process.env.GOOGLE_CLIENT_ID,
clientSecret: process.env.GOOGLE_CLIENT_SECRET,
callbackURL: '/auth/google/callback'
},
async (accessToken, refreshToken, profile, done) => {
// console.log(profile)
const newUser = {
googleId: profile.id,
displayName: profile.displayName,
firstName: profile.name.givenName,
lastName: profile.name.familyName,
image: profile.photos[0].value
}
try {
let user = await User.findOne({ googleId: profile.id })
if (user) {
done(null, user)
} else {
user = await User.create(newUser)
done(null, user)
}
} catch (err) {
console.error(err)
}
}))
passport.serializeUser((user, done) => done(null, user.id))
passport.deserializeUser((id, done) => {
User.findById(id, (err, user) => done(err, user))
})
