Node.js MongoDB Find with projection to exclude _id still returns it

Question

Trying to follow the examples here to filter by using a projection to exclude _id. The _id still returns:

Code

var MongoClient = require(\'mongodb\')         


        

Answer 1

Starting in version 3.4, there is now an option for adding .project() outside of find().

Using ES8 async,await.

Ex:

async function connectDB(url) {

  try {
    const db = await MongoClient.connect(url);     
    const dbase = db.db("db1"); //here  
    
    const results = await dbase.collection("customers").find().project({_id:0}).toArray();

       console.log(result);
       db.close();
  }
  catch(err) {
    throw err;
  }
 }
