[Bug:] SyntaxError: Unexpected token 'export'

[averysmithproductions]

Describe the Bug

vitest is unable to pass certain tests within our repo, of which use the cmsgov-design-system node package. Please note, not all of our tests fail but these 12 do.

To reproduce

1. in your terminal, run git clone https://github.cms.gov/PQDC/pqdc-dkan
2. run git fetch
3. run git checkout https://github.cms.gov/PQDC/pqdc-dkan/pull/1872
4. run cd src/frontend
5. run npm i
6. run npm run test

Expected behavior

within our repo, npm run test generates the following error message:

SyntaxError: Unexpected token 'export'
Module /Users/asmith/Repos/pqdc-dkan/src/frontend/node_modules/@cmsgov/design-system/dist/react-components/esm/index.js:1 seems to be an ES Module but shipped in a CommonJS package. You might want to create an issue to the package "@cmsgov/design-system" asking them to ship the file in .mjs extension or add "type": "module" in their package.json.

As a temporary workaround you can try to inline the package by updating your config:

// vitest.config.js
export default {
  test: {
    server: {
      deps: {
        inline: [
          "@cmsgov/design-system"
        ]
      }
    }
  }
}

This is causing 12 tests to fail. Screenshot below for context:

Please note, the work-around was unsuccesful.

Additional context

In short, I think https://github.com/CMSgov/design-system/blob/main/package.json needs to have a type: "module" property for vitest to be satisfied.

Please note, our work-around may be to just not make vitest required for deployment.

Thanks @averysmithproductions for filling in all the details.

@averysmithproductions I’m hitting a 404 on https://github.cms.gov/PQDC/pqdc-dkan. Could you confirm the correct repo/link, or grant access if it’s private?

[swirtSJW]

Hi @tamara-corbalt sorry I missed this. I am afraid the repo is private and I am not empowered to add people to it. Even if I could, you would not be able to build the site because it needs access to data that involves a whole additional access procedure. Sorry it is not one that is easily tested without additional job codes.

Is this still an issue @averysmithproductions @swirtSJW ?
