vscode配置typescript和eslint的环境

一、typescript配置

tsconfig.build.json

{
  "extends": "./tsconfig.json",
  "compilerOptions": {
    "outDir": "./deploy/dist",
  },
  "exclude": ["node_modules", "dist", "test", "**/*spec.ts"]
}

tsconfig.json

{
  "compilerOptions": {
    "lib": ["es5", "es6"],
    "target": "es6",
    "module": "commonjs",
    "baseUrl": ".",
    "paths": {
        "@common/*":["src/common/*"],
        "@configuration/*":["src/modules/configuration"],
        "@creative/*": ["src/modules/creative/*"],
        "@admin/*": ["src/modules/admin/*"],
        "@auth/*":["src/modules/auth/*"],
    },
    // 允许编译javascript文件
    "allowJs": true,
    // 报告.js文件中的错误。与allowJs一起使用
    "checkJs": true,
    // "plugins": [],
    // 若有未使用的局部变量则抛错
    "noUnusedLocals": false,
    // 若有未使用的参数则抛错
    "noUnusedParameters": false,
    // 类型为any时，是否需要发出警告，设置true，则不警告
    "noImplicitAny": false,
    // 提供迭代器全面支持
    "downlevelIteration": true,
    // 去掉注解
    "removeComments": true,
    // 从tslib导入外部的辅助方法
    "importHelpers": true,
    // 遇到@internal注解时，不会触发代码定义
    "stripInternal": true,
    // 错误信息，跟踪信息将带有颜色和样式
    "pretty": true,
    // 如果不是函数中的所有路径都有返回值，则提示Error
    "noImplicitReturns": true,
    // 允许从没有设置默认导出的模块中默认导入
    "allowSyntheticDefaultImports": true,
    // 使用元数据特性
    "emitDecoratorMetadata": true,
    // 支持ES7的装饰器特性
    "experimentalDecorators": true,
    // 将严格校验switch-case语法
    "noFallthroughCasesInSwitch": true,
    // 严格null检查模式，null和undefined值不包含在任何类型里
    "strictNullChecks": true,
    // 保存上一次的编译信息，下一次进行增量更新
    "incremental": false,
    // 不生成定义文件d.ts
    "declaration": false,
    // 生成.map文件
    "sourceMap": false,
    // 跳过默认库检查
    "skipLibCheck": true,
    // 输出文件的根目录
    "outDir": "./dist",
    // 模块的解析策略
    // "moduleResolution": "node",
  },
  "include": ["src/**/*", "test/**/*"],
  "exclude": ["node_modules", "dist", "test", "**/*spec.ts"]
}

　

二、lint配置

.eslintrc

{
  "parser": "@typescript-eslint/parser",
  "plugins": ["@typescript-eslint", "prettier"],
  "extends": [
    "eslint:recommended",
    "plugin:@typescript-eslint/eslint-recommended",
    "plugin:@typescript-eslint/recommended",
    "plugin:prettier/recommended",
    "standard",
    "prettier/@typescript-eslint",
    "prettier"
  ],
  "parserOptions": {
    "project": "./tsconfig.json"
  },
  "rules": {
    "no-useless-constructor": "off",
    "@typescript-eslint/indent": ["error", 4, { "VariableDeclarator": 4, "SwitchCase": 1 }],
    "@typescript-eslint/no-unused-vars": ["error", {
        "vars": "all",
        "args": "none",
        "ignoreRestSiblings": true
      }],
    "@typescript-eslint/explicit-member-accessibility": ["error", {"accessibility": "no-public"}],
    "@typescript-eslint/explicit-function-return-type": ["off",
      {
        "allowExpressions": true,
        "allowTypedFunctionExpressions": true
      }],
    "@typescript-eslint/interface-name-prefix": 0,
    "@typescript-eslint/no-explicit-any": "off",
    "@typescript-eslint/no-use-before-define": "off",
    "@typescript-eslint/no-parameter-properties": 0,
    "@typescript-eslint/camelcase": ["off", {"properties": "always"}],
    "no-console": ["warn", { "allow": ["warn", "error"] }],
    "eqeqeq": ["warn", "always"]
  },
  "env": {
    "node": true,
    "es6": true,
    "mocha": true,
    "jest": true
  }
}

tslint.json

{
  "defaultSeverity": "error",
  "extends": ["tslint:recommended", "tslint-config-prettier"],
  "jsRules": {
    "no-unused-expression": true
  },
  "rules": {
    "eofline": false,
    "quotemark": [true, "single"],
    "indent": false,
    "member-access": [false],
    "ordered-imports": [false],
    "max-line-length": [true, 450],
    "member-ordering": [false],
    "curly": false,
    "interface-name": [false],
    "array-type": [false],
    "no-empty-interface": false,
    "no-empty": false,
    "arrow-parens": false,
    "object-literal-sort-keys": false,
    "no-unused-expression": false,
    "max-classes-per-file": false,
    "variable-name": [false],
    "one-line": [false],
    "one-variable-per-declaration": [false],
    "semicolon": [true, "always", "ignore-bound-class-methods"],
    "no-console": [false],
    "space-before-function-paren": false,
    "no-shadowed-variable": false
  },
  "rulesDirectory": []
}

.prettierrc.js　　

module.exports = {
    // 一行最多 100 字符
    printWidth: 400,
    // 使用 4 个空格缩进
    tabWidth: 4,
    // 不使用缩进符，而使用空格
    useTabs: false,
    // 行尾需要有分号
    semi: true,
    // 使用单引号
    singleQuote: true,
    // 末尾不需要逗号
    trailingComma: "es5",
    // 大括号内的首尾需要空格
    bracketSpacing: true,
    // 箭头函数，只有一个参数的时候，也需要括号
    arrowParens: "always",
    parser: 'typescript'
};
