Unable to import .js file in RN Typescript project

I have a file called Http.js in a module:

export default class Http {    //stuff}

I can access this class from a typescript project as follows:

import Http from 'myproject.core/services/Http';

I recently published the module containing this class to npm and after installing it in the same typescript project, i can nolonger access this class.

Is there a way i should be doing things to make this class accessible if published via npm?
