vue项目，在githook中添加eslint

全局安装eslint

npm i -g eslint

配置.eslintrc.js(或者eslintrc.json)

在你的根目录下新建.eslintrc.js
cd ~
vi .eslintrc.js
复制下面的code

这里使用vue-cli默认的.eslintrc.js

{
  root: true,
  parserOptions: {
    parser: 'babel-eslint'
  },
  env: {
    browser: true,
    es6: true,
    node: true
  },
  extends: [
    // https://github.com/vuejs/eslint-plugin-vue#priority-a-essential-error-prevention
    // consider switching to `plugin:vue/strongly-recommended` or `plugin:vue/recommended` for stricter rules.
    'plugin:vue/essential', 
    // https://github.com/standard/standard/blob/master/docs/RULES-en.md
    'standard'
  ],
  // required to lint *.vue files
  plugins: [
    'vue'
  ],
  // add your custom rules here
  rules: {
    // allow async-await
    'generator-star-spacing': 'off',
    'no-tabs':'off',
    // allow debugger during development
    'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off'
  }
}

安装依赖

npm i -g eslint-plugin-vue eslint-config-standard eslint-plugin-import eslint-plugin-node eslint-plugin-promise eslint-plugin-standard

运行eslint （主要是为了检测是否缺少依赖）

eslint ./src/*

根据提示安装你缺少的依赖

修改git钩子函数(也可以直接修改.git/hooks/pre-commit文件)

1、在项目根目录下新建.hooks目录
2、在目录里新建pre-commit
3、复制下面的shell代码

#!/bin/sh
STAGED_FILES=$(git diff --cached --name-only --diff-filter=ACM | grep ".jsx\{0,1\}$")
if [[ "$STAGED_FILES" = "" ]]; then
  exit 0
fi
PASS=true
echo "\nValidating Javascript:\n"
# Check for eslint
which eslint &> /dev/null
if [[ "$?" == 1 ]]; then
  echo "\t\033[41mPlease install ESlint\033[0m"
  exit 1
fi
for FILE in $STAGED_FILES
do
  eslint "$FILE"
  if [[ "$?" == 0 ]]; then
    echo "\t\033[32mESLint Passed: $FILE\033[0m"
  else
    echo "\t\033[41mESLint Failed: $FILE\033[0m"
    PASS=false
  fi
done
echo "\nJavascript validation completed!\n"
if ! $PASS; then
  echo "\033[41mCOMMIT FAILED:\033[0m Your commit contains files that should pass ESLint but do not. Please fix the ESLint errors and try again.\n"
  exit 1
else
  echo "\033[42mCOMMIT SUCCEEDED\033[0m\n"
fi
exit $?

添加npm命令

在package.json中添加命令

"postinstall": "cp .hooks/* .git/hooks/"
