Hello I'd like to exclude some fields by query,. Im using nodejs

public async getDoc() {
        return new Promise((resolve, reject) => {
            this.database.collection('users').find({email: "value3"}, {password: 0}).toArray((err, result) => {
                if(err) {
                    reject(err)
                }
                resolve(result);
            });
        })
    }

Projection doesn't work with the new nodejs mongodb driver... Instead you will have to use .project() cursor method here

this.database.collection('users')
  .find({ "email": "value3" })
  .project({ "password": 0 })
  .toArray();
