查看node是否安装
node -v
mkdir template
cd template
npm init
自动生成package.json文件，内容如下：
{
"name": "ts-template",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [
"ts"
],
"author": "jeff.fu",
"license": "ISC"
}- 在src的目录下，创建./src/index.ts
- 在src的目录下，创建index.html
安装typescript
cnpm install typescript --save-devtypescript 编译器，用来将ts文件编译为js文件。
tsc --init生成tsconfig.json

tsconfig.json配置可以参考：https://typescript.bootcss.com/tsconfig-json.html
cnpm install webpack webpack-cli --save-dev
webpack 是一个用于现代 JavaScript 应用程序的 静态模块打包工具。
webpack-cli 提供了许多命令来使 webpack 的工作变得简单。
cnpm install --save-dev webpack-dev-server
webpack-dev-server 可用于快速开发应用程序，支持热插拔。
cnpm install --save-dev ts-loader
ts-loader: This is the TypeScript loader for webpack，解析ts文件转换成浏览器可以识别的文件
build/webpack.config.js文件内容如下：
const HtmlWebpackPlugin = require('html-webpack-plugin')
const { CleanWebpackPlugin } = require('clean-webpack-plugin')
//使用node的模块
module.exports = {
//这就是我们项目编译的入口文件
entry: "./src/index.ts",
output: {
filename: "main.js"
},
resolve: {
extensions: ['.ts','tsx','.js']
},
//这里可以配置一些对指定文件的处理
//这里匹配后缀为ts或者tsx的文件
//使用exclude来排除一些文件
module:{
rules:[
{
test:/\.tsx?$/,
use:'ts-loader',
exclude: /node_modules/
}
]
},
//这个参数就可以在webpack中获取到了
devtool: process.env.NODE_ENV === 'production'? false : 'inline-source-map',
devServer:{
//这个本地开发环境运行时是基于哪个文件夹作为根目录
contentBase:'./dist',
//当你有错误的时候在控制台打出
stats: 'errors-only',
//不启动压缩
compress: false,
host: 'localhost',
port: 8081
},
//这里就是一些插件
plugins:[
new CleanWebpackPlugin({
cleanOnceBeforeBuildPatterns: ['./dist']
}),
new HtmlWebpackPlugin({
template: './src/template/index.html'
})
]

HTML Webpack Plugin， Plugin that simplifies creation of HTML files to serve your bundles。
安装脚本
npm i --save-dev html-webpack-plugin@latest用于设置环境变量的,方便设置开发环境和生产环境
cnpm install cross-env --save-dev
clean-webpack-plugin 能清理一些指定的文件夹
cnpm install clean-webpack-plugin html-webpack-plugin --save-devESLint 是一个代码检查工具，主要用来发现代码错误、统一代码风格，目前已被广泛的应用于各种 JavaScript 项目中。
TypeScript 除了是一个编译 ts 文件的工具以外，还可以作为一个静态代码检查工具使用。TypeScript 会对文件进行语法解析，如果遇到一些语法错误，或使用了未定义的变量，则会报错。
ESLint 也会对文件进行语法解析，它可以对一些代码风格进行约束，发现未定义的变量，但是对于错误的属性或方法引用，却无能为力。
cnpm 安装eslint脚本：
cnpm install eslint --save-dev
npx eslint --init
cnpm install @typescript-eslint/eslint-plugin@latest @typescript-eslint/parser@latest --save-dev
@typescript-eslint/eslint-plugin: An ESLint plugin which provides lint rules for TypeScript codebases. https://www.npmjs.com/package/@typescript-eslint/eslint-plugin
@typescript-eslint/parser: An ESLint parser which leverages TypeScript ESTree to allow for ESLint to lint TypeScript source code. https://www.npmjs.com/package/@typescript-eslint/parser
eslint-plugin-import: This plugin intends to support linting of ES2015+ (ES6+) import/export syntax, and prevent issues with misspelling of file paths and import names. All the goodness that the ES2015+ static module syntax intends to provide, marked up in your editor.https://www.npmjs.com/package/eslint-plugin-import
cnpm install eslint-plugin-import --save-dev
选择使用airbnb的规范：
cnpm install eslint-config-airbnb-typescript@latest --save-dev参考：eslint的规则 、typescript-eslint的规则、airbnb的规则
根据自己喜好，适当修改规范
rules: {
indent: ['error', 'tab'],
'linebreak-style': ['error', 'windows'],
quotes: ['error', 'single'],
semi: ['error', 'always'],
'class-methods-use-this': 0,
'import/extensions': 0,
'no-plusplus': 0,
'no-unused-vars': [
'error',
{ vars: 'all', args: 'none', ignoreRestSiblings: false },
],
'max-len': 0,
'no-underscore-dangle': 'off',
'no-param-reassign': ['error', { props: false }],
'no-console': 'off',
},# don't ever lint node_modules
node_modules
# don't lint build output (make sure it's set to your correct build folder name)
dist
https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint
File-> Preference->Setting->Workspace->open setting.json在setting.json文件中添加如下配置
{
"eslint.alwaysShowStatus": true,
"eslint.format.enable": true,
"eslint.lintTask.enable": true,
"eslint.validate": ["typescript"],
"editor.codeActionsOnSave": {
"source.fixAll.eslint": true
},
"files.eol": "\n"
}上边weapack的命令已经写好了，下边我们就在package.json文件中写指定的命令：
"scripts": {
"start": "cross-env NODE_ENV=development webpack serve --config ./build/webpack.config.js",
"build": "cross-env NODE_ENV=production webpack --config ./build/webpack.config.js"
},``
cnpm install mocker-api --save-dev
创建mock/mocker.js
const proxy = {
'GET /api/user': { id: 1, username: 'kenny', sex: 6 },
'GET /api/user/list': [
{ id: 1, username: 'kenny', sex: 6 },
{ id: 2, username: 'kenny', sex: 6 }
],
'POST /api/#/account': (req, res) => {
const { password, username } = req.body
if (password === '888888' && username === 'admin') {
return res.send({
status: 'ok',
code: 0,
token: 'sdfsdfsdfdsf',
data: { id: 1, username: 'kenny', sex: 6 }
})
} else {
return res.send({ status: 'error', code: 403 })
}
},
'DELETE /api/user/:id': (req, res) => {
console.log('---->', req.body)
console.log('---->', req.params.id)
res.send({ status: 'ok', message: '删除成功！' })
}
}
module.exports = proxy;
在webpack.config.js中添加如下配置
devServer: {
before(app) {
apiMocker(app, resolve('./mock/mocker.js'));
},
},
