`allCountries` undefined in Jest

[jasonburrows]

Here's a minimal reproduction:

import { allCountries } from 'country-region-data';

  test.only('countries should be defined', async () => {
    expect(allCountries).toBeDefined();
  });

Result:

    expect(received).toBeDefined()

    Received: undefined

Note that version 2.7.0 of country-region-data does not exhibit this behaviour (I can change nothing but the version and the test passes). Also note that v3.0.0 works correctly in the associated application, it is specifically the Jest test suite where it is undefined (and in the application itself when running in Jest).

Version information:

jest: 29.7.0
country-region-data: 3.0.0
node: 18.15.0

+1 to this issue, but in another context. My project builds a Remix app using vite 5.4.1 and on the server import of the package the value is undefined. Vite is configured in esm server modules, though I'm a bit confused why this would be the problem.

Rolling back to 2.7.0 resolves the issue. I imagine this is a result of adding this to the package.json though specifically why it was included I'm unclear: cac67c8#diff-7ae45ad102eab3b6d7e7896acd08c427a9b25b346470d7bc6507b6481575d519R6

Another possible workaround is to add to vitest config:

    alias: {
      // Module definition is bugged:
      // https://github.com/country-regions/country-region-data/issues/148
      'country-region-data': 'country-region-data/dist/data',
    },
