书写规范是非常重要的，除了统一，还要简洁。
1、VS Code识别编辑规范
在项目根目录新建.editorconfig文件，加入设置：
# editorconfig.org root = true [*] charset = utf-8 end_of_line = lf indent_size = 2 indent_style = space insert_final_newline = true trim_trailing_whitespace = true
2、ESlint规则
在项目根目录新建.eslintrc.json文件，加入设置：
{ "env": { "browser": true, "es2021": true, "jquery": true // $不报错 }, "extends": [ "standard" ], "parserOptions": { "ecmaVersion": 12, "sourceType": "module" }, "rules": { "space-before-function-paren": ["error", { "anonymous": "always", "named": "never", "asyncArrow": "always" }] } }
3、VS Code保存去掉自动加分号、逗号、双引号
在VS Code的是settings.json插入：
{ "prettier.useEditorConfig": true, "prettier.jsxSingleQuote": true, "prettier.singleQuote": true, "prettier.trailingComma": "none", "prettier.semi": false, "[javascript]": { "editor.defaultFormatter": "esbenp.prettier-vscode" }, "editor.formatOnSave": false, "editor.codeActionsOnSave": { // For ESLint "source.fixAll.eslint": true, // For TSLint "source.fixAll.tslint": true, // For Stylelint "source.fixAll.stylelint": true }, "[html]": { "editor.defaultFormatter": "HookyQR.beautify" }, "files.exclude": { "node_modules": true }, }
