Recursive References in TypeScript

I'm stuck with a very specific TS/JS problem, which may not be solvable but I thought I'd see if anyone here has a cool idea on how to solve it.

So I have a file

index.ts

index.ts

with a mapping from some keys to objects:

import A from "a.ts";
import B from "b.ts";
...

const mapping = {
    "a": A,
    "b": B,
    ...
};

import A from "a.ts";
import B from "b.ts";
...

const mapping = {
    "a": A,
    "b": B,
    ...
};

Then, in the files that contain the objects, they may refer to each other, e.g. in

a.ts

a.ts

I may have:

import B from "b.ts";

const A = {
    "something": B;
    ...
}

export default A;

import B from "b.ts";

const A = {
    "something": B;
    ...
}

export default A;

Currently with this setup, I get

__WEBPACK_DEFAULT_EXPORT__

__WEBPACK_DEFAULT_EXPORT__

and

Cannot access 'B' before initialization

Cannot access 'B' before initialization

errors.
