To set this up properly, we need to have a serialize function and a deserialize function. In Passport, we create these with `passport.serializeUser( OURFUNCTION )` and `passport.deserializeUser( OURFUNCTION )`
The `serializeUser` is called with 2 arguments, the full user object and a callback used by passport. A unique key to identify that user should be returned in the callback, the easiest one to use being the user's `_id` in the object. It should be unique as it generated by MongoDB. Similarly, `deserializeUser` is called with that key and a callback function for passport as well, but, this time, we have to take that key and return the full user object to the callback. To make a query search for a Mongo `_id`, you will have to create `const ObjectID = require('mongodb').ObjectID;`, and then to use it you call `new ObjectID(THE_ID)`. Be sure to add `mongodb@~3.6.0` as a dependency. You can see this in the examples below:
