珠峰架构师成长计划

1.搭建开发环境 #

1.1 初始化项目 #

mkdir 2019zfkt
cd 2019zfkt
cnpm init -y
touch .gitignore

1.2 安装依赖 #

@types开头的包都是typeScript的声明文件，可以进入node_modules/@types/XX/index.d.ts进行查看
常见的声明文件

cnpm i react react-dom @types/react @types/react-dom react-router-dom @types/react-router-dom react-transition-group @types/react-transition-group react-swipe @types/react-swipe antd qs @types/qs -S
cnpm i webpack webpack-cli webpack-dev-server html-webpack-plugin -D
cnpm i typescript ts-loader source-map-loader style-loader css-loader less-loader less url-loader file-loader -D
cnpm i redux react-redux @types/react-redux redux-thunk  redux-logger @types/redux-logger redux-promise @types/redux-promise -S
cnpm i connected-react-router -S
cnpm i express express-session body-parser cors axios -S

ts-loader可以让Webpack使用TypeScript的标准配置文件tsconfig.json编译TypeScript代码。
source-map-loader使用任意来自Typescript的sourcemap输出，以此通知webpack何时生成自己的sourcemaps,这让你在调试最终生成的文件时就好像在调试TypeScript源码一样。

1.3 支持typescript #

需要生成一个tsconfig.json文件来告诉ts-loader如何编译代码TypeScript代码

tsc --init

{
  "compilerOptions": {
    "outDir": "./dist",
    "sourceMap": true,
    "noImplicitAny": true,
    "module": "commonjs",
    "target": "es5",
    "jsx": "react",
    "esModuleInterop":true
  },
  "include": [
    "./src/**/*"
  ]
}

项目	含义
outDir	指定输出目录
sourceMap	把ts 文件编译成 js 文件的时候，同时生成对应的sourceMap文件
noImplicitAny	如果为true的话，TypeScript 编译器无法推断出类型时，它仍然会生成 JavaScript 文件，但是它也会报告一个错误
module：代码规范	target：转换成es5
jsx	react模式会生成React.createElement，在使用前不需要再进行转换操作了，输出文件的扩展名为.js
include	需要编译的目录
allowSyntheticDefaultImports	允许从没有设置默认导出的模块中默认导入。这并不影响代码的输出，仅为了类型检查。
esModuleInterop	设置 esModuleInterop: true 使 typescript 来兼容所有模块方案的导入

在 TypeScript 中，有多种 import 的方式，分别对应了 JavaScript 中不同的 export
// commonjs 模块
import * as xx from 'xx';
// 标准 es6 模块
import xx from 'xx';

1.4 编写webpack配置文件 #

webpack.config.js

const webpack=require('webpack');
const HtmlWebpackPlugin=require('html-webpack-plugin');
const path=require('path');
module.exports={
    mode: 'development',
    entry: "./src/index.tsx",
    output: {
        filename: "bundle.js",
        path: path.join(__dirname,'dist')
    },
    devtool: "source-map",
    devServer: {
        hot: true,
        contentBase: path.join(__dirname,'dist'),
        historyApiFallback: {
            index:'./index.html'
        }
    },
    resolve: {
        alias:{
            "~":path.resolve(__dirname,'node_modules')
        },
        extensions: [".ts", ".tsx", ".js", ".json"]
    },

    module: {
        rules: [{
                test: /\.(j|t)sx?$/,
                loader: "ts-loader",
                exclude:/node_modules/
            },
            {
                enforce: "pre",
                test: /\.js$/,
                loader: "source-map-loader"
            },
            {
                test: /\.css$/,
                use:['style-loader','css-loader']
            },
            {
                test: /\.less$/,
                use:['style-loader','css-loader','less-loader']
            },
            {
                test: /\.(gif|svg|png|jpg|jpeg)$/,
                use:['url-loader']
            }
        ]
    },

    plugins: [
        new HtmlWebpackPlugin({
            template:'./src/index.html'
        }),
        new webpack.HotModuleReplacementPlugin()
    ],
};
