describe the bug

Nyc reprter doesn't report coverage when excludeAfterRemap is set to true in common-utils.js file (default plugin configuration), when testing an angular 8+ app.

workaround

Set excludeAfterRemap to true in common-utils.js file.

Great bug report, so nice, I will link it in the github issue template as an example!

workaround

In package.json set the option

{
  "nyc": {
    "excludeAfterRemap": false
  }
}

Let me see if we can do more in this plugin to solve this, problem is, excludeAfterRemap is not documented in NYC itself

[bahmutov]

Initially, I set excludeAfterRemap: true in examples/exclude-files because in non-interactive mode parcel kept adding coverage for files in the nyc.exclude list. I think it is better to let it be, and explain to the user how to filter files later on.
