Answer 1

You need to use husky package. Here is basic configuration (put it in package.json). It adds pre-commit hook to your git configuration.

"husky": {
  "hooks": {
    "pre-commit": "CI=true npm run test",
  }
}

You can also consider using lint-staged to lint files which you commit. You can see full configuration here.
