React NPM inefficient regular expression complexity in nth-check

Question

I googled lot about this issue. But could not find this issue belongs to which library? How to fix it? any help will be appreciated

Answer 1

This is a known issue, and it should not affect your actual app as it's coming from react-scripts package.

Open package.json. You will find this:

  "dependencies": {
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "react-scripts": "4.0.3"
  }

Take react-scripts and move it to devDependencies (if you don't have it, create it):

  "dependencies": {
    "react": "^17.0.2",
    "react-dom": "^17.0.2"
  },
  "devDependencies": {
    "react-scripts": "4.0.3"
  },

Then, ensure you run npm audit --production rather than npm audit.

Answer 2

"resolutions" :{
 "nth-check":"2.0.1"
}

Add it in Package.json then run npm install
