Importing an exported function with name in Typescript

I know that for classes in an export, you can singularly grab classes like so:

import {classA, classB} from "largeExport";

However given an export that contains a function, where it would be used as such:

var sum = require("myAdder")(1, 2)

How do you import it with it's own name?

I know you can import the whole thing and use the function like this:

import * as adder from "myAdder";
var sum = adder(1, 2);

however the export that I'm working with is actually quite big, and importing the whole thing is less than ideal.

its not about "classes" but the way it's been exported

if it was exported as 

export const x = "x";
export class X {};

then

import {x, X} from "./x";

or 

import * as xxx from "./x"
import x = xxx.x;
import X = xxx.X;

if

const x = "x";
export default x;
export class X {};

then 

import x from "./x"

or 

import x, {X} from "./x"

and you will be importing the whole file anyway

if you are concerned about import sizes you might want to split you module into many, more modular files.
