Re-use a native MongoDB driver connection (or a promise)

I am unable to create the following: “Re-use a native MongoDB driver connection (or a promise)”

It always returns the error: “Connection strategy not found”, because in normal Express structure all app.use go before mongoclient.connect (which has app.listen in it).

 var db = {};
 app.use(expresssession({
   secret: 'xxx',
   resave: false,
   saveUninitialized: false,
   store: new mongostore({
      db: db,
      collection: 'sessions',
      ttl: 24 * 60 * 60
   })
}));

mongoclient.connect(mongourl, (error, database) => {
  if (error) return console.log(error);`

  db = database;
  
  app.listen(port, function(){
    console.log('Listening on port: ' + port);
  });
});

The only way I know how to make connect-mongo work with MongoDB driver is by using url instead of db:

store: new mongostore({
    url: mongourl,
    collection: 'sessions',
    ttl: 24 * 60 * 60
  })

but this from all my testing ends up making hundreds of db connections as described in open issue: https://github.com/jdesboeufs/connect-mongo/issues/252

The only advice I can give you is to use mongoose instead of mongodb. It works with connect-mongo without any issues mentioned above. If you’re not sure how to set it up you can watch this video guide. Good luck!
