Learning lint-staged

Just one of the things I'm learning. https://github.com/hchiam/learning

Automatically include code style fixes in your commits with lint-staged, set up with husky.

From scratch

Using yarn:

yarn init
yarn --dev add lint-staged husky@^4.3.0 prettier jest
npx mrm lint-staged

Then clean up your package.json to look something like this:

{
  ...
  "scripts": {
    "test": "jest --bail --findRelatedTests",
    "lint": "prettier --write *.{js,css,html,scss,json,md,ts,tsx}"
  },
  "dependencies": {},
  "devDependencies": {
    "husky": "^4.3.0",
    "jest": "^27.0.4",
    "lint-staged": "^11.0.0",
    "prettier": "^2.3.1"
  },
  "husky": {
    "hooks": {
      "pre-commit": "lint-staged"
    }
  },
  "lint-staged": {
    "**/*.js": [
      "jest --bail --findRelatedTests"
    ],
    "*.{js,css,html,scss,json,md,ts,tsx}": "prettier --write"
  }
}

Note: it's important that you include "prepare": "husky install" in the package.json file, otherwise when you git clone and yarn, lint-staged might not run.
