Typescript 1.5 exporting/importing classes

Question

It might be a misunderstanding from my part. In Typescript 1.4 we use to export import classes, but when I updated my code to typescript 1.5 the behavior changed.

Here is how it worked in TS 1.4

LanguageForm.ts

import AbstractForm = require('../components/AbstractForm');

class LanguageForm extends AbstractForm {
    buildPanel(){

    }
}
export = LanguageForm;

From my understanding in TS 1.5 the syntaxt needs to be modify to :

import AbstractForm from '../components/AbstractForm';
export default class LanguageForm extends AbstractForm {
    buildPanel(){

    }
}

Whith TS1.4 I could simply do a call on new in order for it to work in a dynamic setting :

require(["LanguageForm"], (Form) => {
    new Form()
});

now in TS 1.5 I need to do :

require(["LanguageForm"], (Form) => {
    new Form.default()
});

My question In all the example I found the documentation was exporting/importing modules. Is that the way to export/import classes? Can I get rid of the .default?

Don't use export =. Instead export:

export class LanguageForm extends AbstractForm {
    buildPanel(){

    }
}

And import:

import {LanguageForm} from '../components/LanguageForm';
