Introducing Steps

For example, file structure like this...

awesome-project/  # Git repository root
  super-app/
    package.json
  fabulous-function/
    package.json

1. Put this script file on Git repository root

mv lint-staged-around awesome-project/
chmod ugo+x awesome-project/lint-staged-around

2. Install simple-git-hooks in each project

yarn add -D simple-git-hooks lint-staged prettier

3. Edit package.json

    "devDependencies": {
      "lint-staged": "^10.5.4",
      "prettier": "^2.2.1",
      "simple-git-hooks": "^2.0.3"
    },
+  "simple-git-hooks": {
+     "pre-commit": ". ./lint-staged-around"
+   },
+   "lint-staged": {
+     "*.{js,jsx,ts,tsx,json,md}": [
+       "prettier --write"
+     ]
    }

4. Overwrite Git hooks
