1. 安装 prettier 库

npm i -D prettier

2. 配置 package.json

"format": "prettier --write \"src/**/*.{js,jsx,ts,tsx,vue,scss,css}\""

3. 根目录下放这两个文件

.prettierrc

{
  "semi": true,
  "singleQuote": true,
  "tabWidth": 2,
  "printWidth": 120,
  "trailingComma": "es5",
  "arrowParens": "always",
  "singleAttributePerLine": false,
  "htmlWhitespaceSensitivity": "ignore",
  "endOfLine": "auto"
}

.prettierignore

dist
node_modules
*.md
*.yml
*.yaml
*.json
*.lock

4. 可以再装一个 prettier 插件比较舒服，记得默认的format 选择 prettier
