[0.19.5] Docs and example now error regarding use of setupWorker in Node

Describe the bug

Not really a bug, just a discrepancy between the documentation/example and the behavior in the latest release. #219 throws an error when you try to use setupWorker in Node (e.g. Jest tests), but the documentation and the rest-react example both call it directly in the mocks file, so you can’t use that same file in the browser and Node-based tests.

Environment

• msw: 0.19.5
• nodejs: 12.18.1
• npm: 6.14.5

Browser: N/A

To Reproduce

Steps to reproduce the behavior:

1. Setup rest-react example
2. Run npm run test:unit
3. See error:

   [MSW] Failed to execute `setupWorker` in a non-browser environment. Consider using `setupServer` for NodeJS environment instead.
   

Expected behavior

I expected the example to work and the steps in the documentation to produce a working structure.

Possible solutions

Is it just a matter of restructuring the docs/example to match the graphql-react-apollo example where the handlers are separate from the setupWorker/setupServer calls?

I’ve updated the “Getting stared” tutorial to recommend the proper file structure. Thanks once more for bringing this up.

That’s definitely a valid concern. I’ve opened an issue in the docs about that: https://github.com/mswjs/mswjs.io/issues/9
