TS: Re-exporting a class scoped to a namespace

Question

I would like to have a namespace be the hub of classes for a strategy in my system. The reason it has to be a namespace is that was the best way to do dynamic class generation, as the window object method proved fruitless.

I would like to re-export this file

// Bar.ts export class Bar { public log() {console.log('I'm in Bar);} }

from the following namespace as such

//Foo.ts export namespace Foo { export Bar from './bar.ts' // <- how do I do this? }

You can re-export something you imported outside of the namespace:

import * as BarFile from "./Bar"; export namespace Foo { export import Bar = BarFile.Bar; }

There may be a better way to export it without the import * as BarFile, but I still use it this way.

Thanks a ton! A quick follow up question, what is the syntax export import Bar = BarFile.Bar ? Is there a document page you can quickly recommend to book up on that?

Honestly, I don't know how I know that, I think I searched around when I faced this issue and then I have this code example on my project for some years now. I think this is an extrapolation from the import syntax import _ = require('lodash'); applied to namespace's export <statement>.
