Does not work with Create React App

Hey,

I have followed the official docs but yet unable to make it work with my react app. I use create-react-app utility and not webpack and babel. It does create coverage and .nyc_output folder but no coverage is being calculated.

npx nyc report --reporter=text-summary

=========== Coverage summary ===============================
Statements   : Unknown% ( 0/0 )
Branches     : Unknown% ( 0/0 )
Functions    : Unknown% ( 0/0 )
Lines        : Unknown% ( 0/0 )
==============================================================

@judsoncarver See a couple of TypeScript examples linked in https://github.com/cypress-io/code-coverage#examples Since TS files are NOT automatically included in the report, you need to add NYC settings like https://github.com/lluia/cypress-typescript-coverage-example/blob/master/package.json#L13 I think

"nyc": {
  "extends": "@istanbuljs/nyc-config-typescript",
  "all": true
}

You can use https://github.com/cypress-io/instrument-cra to instrument CRA v3 apps without ejecting the scripts
