VScode+Typescript+Less+Bootstrap3+Eslint环境搭建
作者：互联网
该环境支持：
a、VSCode中自动编译Typescript；
b、TypeScript 支持jquery、bootstrap；
c、ESLint保存时自动检查Typescript代码；
d、VScode自动编译Less；
e、Eslint自动检查Html中的JavaScript代码；
f、具有本地服务器功能；
步骤：
1、VScode中安装Eslint和live Server（本地服务器）插件；
2、按照以下package.json安装相应的开发包：
{
"name": "FirmStor",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"@types/bootstrap": "^4.3.1",
"@types/jquery": "^3.3.32",
"@typescript-eslint/eslint-plugin": "^2.19.0",
"@typescript-eslint/parser": "^2.19.0",
"eslint": "^6.8.0",
"eslint-plugin-html": "^6.0.0",
"typescript": "^2.9.2"
}
}
3、配置tsconfig.json：

// "strictPropertyInitialization": true, /* Enable strict checking of property initialization in classes. */
// "noImplicitThis": true, /* Raise error on 'this' expressions with an implied 'any' type. */
// "alwaysStrict": true, /* Parse in strict mode and emit "use strict" for each source file. */
/* Additional Checks */
// "noUnusedLocals": true, /* Report errors on unused locals. */
// "noUnusedParameters": true, /* Report errors on unused parameters. */
// "noImplicitReturns": true, /* Report error when not all code paths in function return a value. */
// "noFallthroughCasesInSwitch": true, /* Report errors for fallthrough cases in switch statement. */
/* Module Resolution Options */
// "moduleResolution": "node", /* Specify module resolution strategy: 'node' (Node.js) or 'classic' (TypeScript pre-1.6). */
// "baseUrl": "./", /* Base directory to resolve non-absolute module names. */
// "paths": {}, /* A series of entries which re-map imports to lookup locations relative to the 'baseUrl'. */
// "rootDirs": [], /* List of root folders whose combined content represents the structure of the project at runtime. */
// "typeRoots": [], /* List of folders to include type definitions from. */
// "types": [], /* Type declaration files to be included in compilation. */
// "allowSyntheticDefaultImports": true, /* Allow default imports from modules with no default export. This does not affect code emit, just typechecking. */
"esModuleInterop": true, /* Enables emit interoperability between CommonJS and ES Modules via creation of namespace objects for all imports. Implies 'allowSyntheticDefaultImports'. */

},
"include": [
"src/**/*"
],
"exclude": [
"node_modules"
]
}
4、配置.eslintrc.json：
{
"parser": "@typescript-eslint/parser",
"plugins": [
"@typescript-eslint",
"html"
],
"parserOptions": {
"ecmaVersion": 6,
"sourceType": "module"
},
"extends": [
"eslint:recommended",
"plugin:@typescript-eslint/eslint-recommended",
"plugin:@typescript-eslint/recommended"
],
"env": {
"node": true,
"browser": true,
"commonjs": true,
"es6": true,
"jquery": true
},
"rules": {
"no-alert": 0 //禁止使用alert confirm prompt
}
}5、安装VScode插件Easy LESS；
6、VScode的配置文件setting.json中添加如下代码使得在文件保存时ESlint自动检查代码格式：
"files.autoSave": "off",
"eslint.autoFixOnSave": true,
"eslint.run": "onSave",
"eslint.validate": [
"javascript",
"html",
{
"language": "jsx",
"autoFix": true
},
{
"language": "html",
"autoFix": true
},
{
"language": "typescript",
"autoFix": true
}
]6、VScode的配置文件setting.json中添加如下代码使得在编辑Less文件保存时，自动生成相应的Css：
"less.compile": {
"compress": false,
"sourceMap": false,
"out": "${workspaceRoot}\\dist\\static\\css\\", // 这里是代表编译后生成的css文件所放的位置
},编辑后的setting.json文件为：
{
"files.autoSave": "off",
"eslint.autoFixOnSave": true,
"eslint.run": "onSave",
"eslint.validate": [
"javascript",
"html",
{
"language": "jsx",
"autoFix": true
},
{
"language": "html",
"autoFix": true
},
{
"language": "typescript",
"autoFix": true
}
],
"terminal.integrated.rendererType": "dom",
"less.compile": {
"compress": false,
"sourceMap": false,
"out": "${workspaceRoot}\\dist\\static\\css\\", // 这里是代表编译后生成的css文件所放的位置
},
"liveServer.settings.donotVerifyTags": true
