What is the best way to set a JS variable to the value of a MongoDB field?

I am currently facing an issue where I need to assign a JS variable to a MongoDB field. The code I have written is returning the entire object instead of just the string value assigned to the field. For instance, if I have a document with the field

{name: "dylan"}

I don't want the entire object to be returned, I only need the string "dylan". Below is the code I have attempted:

var game = SearchLobby.findOne(
  {profile: Meteor.userId()},
  {game: 1,_id: 0}
);

Answer №1

let currentUser = Meteor.userId();
{gameName: SearchLobby.findOne({profile: currentUser}, {game: 1, _id: 0}).game}

This method seems to be the most effective way to fetch the game name from the document. I can't think of any other approach that would work better.

Answer №2

By including the field you desire using dot notation (.name) in your query result, you will receive the string value contained within the field as an object.

 var game = SearchLobby.findOne(
   {profile: Meteor.userId()},
   {game: 1, _id: 0}
 ).game;

The variable "game" should hold the string value of the name stored within it.
