[jitenderchand1]

Description

I have created app using create-react-app and I have been trying to set up lint-staged with husky. I have 4 stages but it hangs on npm run test.

Steps to reproduce

create react app using create-react-app and then replace following package.json into project directory.

I’m closing since there are no debug logs attached. Unless these are provided I believe we can’t help any further.

@okonet I had my lint-staged and it works!. I don't what was the issue but its seems fine now. But still if i use npm run test it hangs forever. Might be CI=true is doing some magic.

"scripts": {
    ...
    "test": "react-scripts test",
    "test:staged": "cross-env CI=true react-scripts test --coverage --env=jsdom --findRelatedTests"
  },

"lint-staged": {
    "*.js": [
      "prettier --write",
      "eslint src/ --fix",
      "npm run test:staged",
      "git add"
    ]
  }

@jitenderchand1 try using the --watchAll=false flag as well .. react-scripts test runs by default in watch mode, but that doesn't jive with lint-staged .. hope this helps!
