Cannot add new collection in mongodb in mLab

Question

I am following full-stack react course by stephen grider. Everything looks good but after google social auth, I can't see new users collection getting added to the mLab database.

I am using passport.js and mongoose.js.

Here is the relevant source code:

index.js

const express = require('express');
const mongoose = require('mongoose');
const keys = require('./config/keys');
require('./models/User');
require('./services/passport');

mongoose.connect(keys.mongoURI);

const app = express();

require('./routes/authRoutes')(app);

const PORT = process.env.PORT || 5000;
app.listen(PORT)

user.js

const mongoose = require('mongoose');
const { Schema } = mongoose;

const userSchema = new Schema({
  googleId: String
});

mongoose.model('users', userSchema);    

passport.js

const passport = require('passport');
const GoogleStrategy = require('passport-google-oauth20').Strategy;
const mongoose = require('mongoose');
const keys = require('../config/keys');

const User = mongoose.model('users');

passport.use(
  new GoogleStrategy(
    {
      clientID: keys.googleClientID,
      clientSecret: keys.googleClientSecret,
      callbackURL: '/auth/google/callback'
    },
    (accessToken, refreshToken, profile, done) => {
      new User({ googleId: profile.id }).save();
      console.log('accessToken',accessToken,'profile',profile)
    }
  )
);

Could anyone please let me know where I am making mistake because of which new collection is not getting created in the MongoDB database?

Answer 1

The issue was in the user.js file. Defining Schema alone doesn't work. You will need to export it too.

const mongoose = require('mongoose');
const { Schema } = mongoose;

const userSchema = new Schema({
  googleId: String
});

module.exports = mongoose.model('users', userSchema);

Further, if anybody come across this type of error, please make sure you are using correct credentials(username and password) for the particular mongo database.
