This is what worked for me. Using mongoDB

const mongoDB = require('mongodb')

Then at the bottom where I am making my express get call.

router.get('/users/:id', (req, res) => {
const id = req.params.id;
var o_id = new mongoDB.ObjectID(id);

const usersCollection = database.collection('users');

usersCollection.findOne({
  _id: o_id
})

.then(userFound => {
  if (!userFound){
    return res.status(404).end();
  }
  // console.log(json(userFound));
  return res.status(200).json(userFound)
})
.catch(err => console.log(err));

 });`
