If you are using NodeJS and want to get the all the field names using the API request, this code works for me-

let arrayResult = [];

db.findOne().exec(function (err, docs)){
 if(err)
  //show error

  const JSONobj = JSON.parse(JSON.stringify(docs));
     for(let key in JSONobj) {
       arrayResult.push(key);
     }
  return callback(null, arrayResult);
}

The arrayResult will give you entire field/ column names

Output-

[
 "_id",
 "emp_id",
 "emp_type",
 "emp_status",
 "emp_payment"
]

Hope this works for you!
