1.NPMインストール

1.1 huskey

コミット時に何かをトリガーする

 npm uninstall ghooks --save-dev && npm install husky --save-dev

1.2 eslint

構文チェック

 npm install -g eslint --save-dev
 eslint init
	>? How would you like to configure ESLint? Inspect your JavaScript file(s)
	>? Which file(s), path(s), or glob(s) should be examined? ./src/assets/js/

	>? Are you using ECMAScript 6 features? No
	>? Where will your code run? Browser
	>? Do you use CommonJS? Yes
	>? Do you use JSX? No

2.package.jsonでスクリプトの呼び出し設定

  "scripts": {
    "precommit": "npm run test.sh -q || eslint ./src/assets/js/"
  }

3.確認

eslint ./src/assets/js/
npm run precommit
npm run eslint

4. gitコミット時にエラーを確認

git commit
>......
>✖ 1733 problems (1733 errors, 0 warnings)
>
>
> husky - pre-commit hook failed (add --no-verify to bypass)
> husky - to debug, use 'npm run precommit'

5.rails + yarn + VueJS版

yarn add eslint
yarn add eslint-config-vue
yarn add ghooks
yarn add husky

 "scripts": {
    "precommit": "npm run test.sh -q || eslint ./src/assets/js/"
  }

yarn run precommit

package.jsonに記載したprecommitが動いている事を確認
