@jskiller1404 oh, we thought about different implantations.
I see this feature as saving current method 'getPublic', details are in this ticket: https://github.com/orgs/paralect/projects/1?pane=issue&itemId=62396152

that features will be on node-mongo beta right now, could you please rollback it?
When I publish changes, I will add these changes to the doc

[fruneen]

could you please play with return type?
Ideally, If you pass a user with type { _id: string, password: string } and private fields ['password'] return type should be { _id: string } (accessing 'password' field should cause error)

also try to implement types overloading when you pass null, here is high-level example:

interface MyObject {
  foo: string;
  bar: number;
}

// Modified type example
interface ModifiedObject {
  foo: string;
  bar: number;
  baz: boolean;
}

// Overloads
function processObj(obj: null): null;
function processObj(obj: MyObject): ModifiedObject;

// Implementation (single signature)
function processObj(obj: MyObject | null): ModifiedObject | null {
  if (obj === null) return null;
  // Modify object as needed
  return { ...obj, baz: true };
}

Great job!

I'll merge it after testing on my side with new release version of node-mongo
