后面会写一些Typescript相关的一些内容，会先从简单的环境搭建，基本类型，枚举类型，类，接口等基础开始。再慢慢记录一些实战内容。
项目目录结构：
1、安装TS
TS 安装可以选择全局安装
npm i typescript -g
2、TS config
tsc --init
创建成功以后会在跟目录下创建一个tsconfig.json
3、package.json
npm init
会创建一个package.json文件。可以拷贝下面的内容，然后执行npm install 安装
{

}
创建index.html
创建src/tpl/index.html文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>TypeScript in Action</title>
</head>
<body>
<div class="app"></div>
</body>
</html>
创建ts文件
新建src, 新建index.ts
let text: string = 'Hello Typescript';
document.querySelectorAll('.app')[0].innerHTML = hello;
webpack 配置
创建build文件。新建webpack.base.config.js, webpack.config.js, webpack.dev.config.js, webpack.pro.config.js
webpack.base.config.js：
const HtmlWebpackPlugin = require('html-webpack-plugin')
module.exports = {
entry: './src/index.ts',
output: {
filename: 'app.js'
},
resolve: {
extensions: ['.js', '.ts', '.tsx']
},
module: {
rules: [
{
test: /\.tsx?$/i,
use: [{
loader: 'ts-loader'
}],
exclude: /node_modules/
}
]
},
plugins: [
new HtmlWebpackPlugin({
template: './src/tpl/index.html'
})
]
}
webpack.config.js：
const merge = require('webpack-merge')
const baseConfig = require('./webpack.base.config')
const devConfig = require('./webpack.dev.config')
const proConfig = require('./webpack.pro.config')
module.exports = (env, argv) => {
let config = argv.mode === 'development' ? devConfig : proConfig;
return merge(baseConfig, config);
};
webpack.dev.config.js：
module.exports = {
devtool: 'cheap-module-eval-source-map'
}
webpack.pro.config.js：
const { CleanWebpackPlugin } = require('clean-webpack-plugin')
module.exports = {
plugins: [
new CleanWebpackPlugin()
]
}
