findbyid and delete in node docs code example

Example 1: deleteOne mongoose

Tank.deleteOne({ size: 'large' }, function (err) {
  if (err) return handleError(err);
  // deleted at most one tank document
});

Example 2: mongoose remove data

Remove is deprecated - use delete
Update for Mongoose v5.5.3 - remove() is now deprecated.
Use deleteOne(), deleteMany() or findOneAndDelete() instead.
