Jest test: Cannot find module, in typescript component import

The path to my styled objects is correct, however not sure why I’m getting the following error:

Cannot find module ‘../../shared/models’ from ‘Astronaut.tsx’

import { moonHoldings } from ‘../../shared/models’;

My simple Jest test:

import React from 'react';
import { shallow } from 'enzyme';
import toJson from 'enzyme-to-json';

// @ts-ignore (works with .tsx)
import Astronaut from '../Astronaut.tsx';

describe('<Astronaut /> component', () => {
  describe('should render', () => {
    const wrapper = shallow(<Astronaut showLogo={true} />);
    it ('should render a component matching the snapshot', () => {
      const tree = toJson(wrapper);
      expect(tree).toMatchSnapshot();
      expect(wrapper).toHaveLength(1);
    });
  });
});

The Astronaut component

import React from 'react';

import { moonHoldings } from '../../shared/models';  // <-- The problem
import { astronaut } from '../../styles'; // <-- This works

const { AstronautContainer, Heading } = astronaut;

interface LogoCheck {
  showLogo: boolean;
}

export default (showLogo: LogoCheck) =>  (
  <AstronautContainer>
    { showLogo.showLogo === true ? <Heading>{moonHoldings}</Heading> : null }
    <img src="static/astronaut.png" alt="astronaut" />
  </AstronautContainer>
);

The Jest config section of my Package.json

"jest": {
  "setupTestFrameworkScriptFile": "<rootDir>/jest.setup.js",
  "testPathIgnorePatterns": [
    "<rootDir>/.next/",
    "<rootDir>/node_modules/"

  ],
  "modulePaths": [

    "<rootDir>/shared/"
  ]
}

And my folder structure:

Answer

Ok I just fixed this by created an index file inside of the /shared folder and then exporting out the models that way (Though it should have still worked without the index file):

import { moonHoldings } from '../../shared';

And the index.js:

export { moonHoldings, nomicsLink } from './copy';
