Reproduction repository

https://github.com/coinbase/rest-hooks/tree/a3963b2618981992bab115a8e8543abdb9cdc655/website

Gonna revert MSW upgrade to make this work so master will no longer have this problem.

Reproduction steps

1. clone repo above
2. git checkout a3963b2618981992bab115a8e8543abdb9cdc655
3. navigate to website folder
4. yarn install
5. yarn start
6. observe error in cli as well as opened browser tab

Current behavior

ERROR in ./node_modules/msw/lib/node/index.mjs 45:0-94

Module not found: Error: Can't resolve '@mswjs/interceptors/lib/interceptors/ClientRequest' in '/home/ntucker/src/rest-hooks/website/node_modules/msw/lib/node'
Did you mean 'index.js'?
BREAKING CHANGE: The request '@mswjs/interceptors/lib/interceptors/ClientRequest' failed to resolve only because it was resolved as fully specified
(probably because the origin is strict EcmaScript Module, e. g. a module with javascript mimetype, a '*.mjs' file, or a '*.js' file where the package.json contains '"type": "module"').
The extension in the request is mandatory for it to be fully specified.
Add the extension to the request.

https://github.com/mswjs/msw/pull/1247 breaks in node versions that support ESM

Expected behavior

To fix this - the ESM version of MSW must be explicit about file extensions. Otherwise it is by definition incorrectly built. If this cannot be done you should not ship a custom ESM version as this is incorrect. The only reason it would work is if it is used by a system that doesn’t enforce fully (webpack). However this will break in fully-spec compliant things like node.

More simply:

import '@mswjs/interceptors/lib/interceptors/ClientRequest' => import '@mswjs/interceptors/lib/interceptors/ClientRequest.mjs'
