+# eslint
+
+## 功能
+
+eslint（包括其他一些 lint 工具）的主要功能包含代码格式的校验，代码质量的校验
+
+## 使用方式
+
+1. 编译器
+2. webpack
+3. 命令行
+
+* rc配置
+ - parser 指定解析器
+ - ESLint 默认使用Espree作为其解析器
+* rc 的配置可以来源于三处，按优先级排列
+
+ - 项目rc
+ - package.json
+ - 根目录rc
+
+* 编译器
+ 1. 安装插件
+ 2. 该扩展使用安装在打开的工作区文件夹中的 ESLint 库 & eslintrc
+ 3. Visual Studio Code Settings
+ - eslint.validate(默认只校验js)
+ - 错误修复 editor.codeActionsOnSave
+ - 状态栏中显示eslint "eslint.alwaysShowStatus": true
+ - 状态栏不显示警告信息 "eslint.quiet": true

+
+# 集成Prettier
+
+## 功能
+
+ 只是代码格式的校验（并格式化代码），不会对代码质量进行校验
+
+* Prettier 的配置可以来源于三处，按优先级排列
+ 1. Prettier configuration file
+ 2. editorconfig
+ 3. Visual Studio Code Settings
+* 集成方式
+ 1. prettier 规则对 eslint 规则的进行覆盖
+
+``` 
+
+``` JS
+// JavaScript
+{
+ "extends": [
+ ...,
+ "已经配置的规则",
+ "plugin:prettier/recommended"
+ ]
+}
+```
+
+# 限制提交
+
+ 1. husky - 对所有提交对内容进行校验
+ 2. lint-staged - 对修改对内容
+
+``` 
+// package.json
+
+"husky": {
+ "hooks": {
+ "pre-commit": "lint-staged"
+ }
+},
+"lint-staged": {
+ // src 目录下任意文件有改动，都使用 prettier --write 格式化之后再提交
+ "src/**/*.*": [
+ "prettier --write",
+ "git add"
+ ]
+}
+```
