chosen.content: The following code connects an express.js server to a mongodb database through "../database/connection" and allows for the retrieval of a specific element from the database based on a unique id.
  
  const express = require("express");
  const theRoutes = express.Router();
  const dbo = require("../database/connection");
   
  const ObjectId = require("mongodb").ObjectId;
  theRoutes.route("/test/:id").get(function (req, res) {
   let db_connect = dbo.getDb();
   let myquery = { _id: ObjectId(req.params.id) };
   db_connect
     .collection("collection")
     .findOne(myquery, function (err, result) {
       if (err) throw err;
       res.json(result);
     });
  });
