Error on step2 test "SyntaxError: Cannot use import statement outside a module"

[mikhail-g]

Steps:

1. Checkout step2
2. Run tests with npm test --prefix consumer

Outcome:
Jest is panicking on import at axios

Console output:

 FAIL  src/api.spec.js
  ● Test suite failed to run

    Jest encountered an unexpected token

    Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.

    Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.

    By default "node_modules" folder is ignored by transformers.

    Here's what you can do:
     • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it.
     • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/configuration
    For information about custom transformations, see:
    https://jestjs.io/docs/code-transformation

Workaround:
Exclude axios from transformIgnorePatterns to be transformed by Jest. Add the jest config field to package.json (or add jest.config file):

  "jest": {
    "transformIgnorePatterns": [
      "node_modules/(?!(axios)/)"
    ]
  }

Hey thanks @mikhail-g,

It seems I missed that out on step1/2/3.

Your solution is neater than mine

I'll make sure to update and propagate through the steps
