NodeJS Async connection to Mongo DB

I am trying to write a async function in nodejs that I will use to display data in my front-end. Can anyone point out my error. It is probably fairly obvious.

    export function getData() {

      const client = new MongoClient(url);
      var query = {"pos_date" : "2019-07-18"};
      console.log('get mongo data');

      return new client.connect((url).dbo.dbo.collection("positions_eod").find(query).toArray())
        return data;
