Serialization of a User Object (hint)

What is your hint or solution suggestion?

Your solution should include two functions (they are both given to you):

  • A serialization function
  • A deserialization function (the db.collection should be commented out because we have not yet set up our DB)

Also add const ObjectID = require('mongodb').ObjectID; to your server.js file (To make a query search for a Mongo _id)

The 2 functions:

passport.serializeUser((user, done) => {
  done(null, user._id);
passport.deserializeUser((id, done) => {
  db.collection('users').findOne( // comment out starting here
    {_id: new ObjectID(id)},
      (err, doc) => {
        done(null, doc);
  ); // Comment out until here

Don’t forget to add mongoose and mongodb as dependencies in the package.json file
