1.從零開始搭建webpack+react開發(fā)環(huán)境

2.引入Typescript

安裝依賴

npm i -S @types/react @types/react-dom
npm i -D typescript awesome-typescript-loader source-map-loader

新建tsconfig.json

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

修改webpack.config.js

// webpack.config.js
const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const webpack = require("webpack");


module.exports = {
    entry: {
        index:"./src/index.js",
    },
    output: {
        filename: "bundle.js",
        path: path.resolve(__dirname, "dist")
    },
    devtool: "source-map",
    // Add ".ts" and ".tsx" as resolvable extensions.
    resolve: {
        extensions: [".ts", ".tsx", ".js", ".jsx"]
    },
    module: {
        rules: [
            {
                test: /.css$/,
                use: ["style-loader", "css-loader"]
            },
            {
                test: /.(png|svg|jpg|gif)$/,
                use: ["url-loader"]
            },
            {
                test: /.(woff|woff2|eot|ttf|otf)$/,
                use: ["url-loader"]
            },
            {
                test: /.(js|jsx)$/,
                exclude: /node_modules/,
                use: {
                    loader: "babel-loader"
                }
            },
            // All files with a ".ts" or ".tsx" extension will be handled by "awesome-typescript-loader".
            {
                test: /.tsx?$/,
                loader: "awesome-typescript-loader"
            },
        ]
    },
    plugins: [
        new HtmlWebpackPlugin({
            title: "production",
            template: "./index.html"
        }),
        new webpack.NamedModulesPlugin(),
        new webpack.HotModuleReplacementPlugin()
    ],
    devServer: {
        contentBase: "./dist",
        hot: true
    },
};

3.引入less并支持import less modules

安裝依賴

npm i -D less less-loader
npm i -D typings-for-css-modules-loader

tips: typings-for-css-modules-loader

打包時(shí)將樣式模塊化，我們可以通過import或require引入樣式，并且相互不沖突。

//demo.less -> demo.less.d.ts
//.demo{color:red;} -> export const demo: string;
import * as styles from "demo.less"
 

修改webpack.config.js

// webpack.config.js
const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const webpack = require("webpack");


module.exports = {
    entry: {
        index:"./src/index.js",
    },
    output: {
        filename: "bundle.js",
        path: path.resolve(__dirname, "dist")
    },
    devtool: "source-map",
    //add .less
    resolve: {
        extensions: [".ts", ".tsx", ".js", ".jsx", ".less", ".css"]
    },
    module: {
        rules: [
            {
                test: /.css$/,
                use: ["style-loader", "css-loader"]
            },
            //import less modules，name：demo__demo___hash
            {
                test: /.less/,
                use: [
                    "style-loader",
                    "typings-for-css-modules-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]&namedExport&camelCase&less!less-loader"
                ]
            },
            {
                test: /.(png|svg|jpg|gif)$/,
                use: ["url-loader"]
            },
            {
                test: /.(woff|woff2|eot|ttf|otf)$/,
                use: ["url-loader"]
            },
            {
                test: /.(js|jsx)$/,
                exclude: /node_modules/,
                use: {
                    loader: "babel-loader"
                }
            },
            {
                test: /.tsx?$/,
                loader: "awesome-typescript-loader"
            },
        ]
    },
    plugins: [
        new HtmlWebpackPlugin({
            title: "production",
            template: "./index.html"
        }),
        new webpack.NamedModulesPlugin(),
        new webpack.HotModuleReplacementPlugin()
    ],
    devServer: {
        contentBase: "./dist",
        hot: true
    },
};

4.引入react-routerv4

npm i -S react-router-dom

創(chuàng)建history

import { createHashHistory } from "history";
export default createHashHistory();

使用

import React from "react";
import ReactDom from "react-dom";
import * as styles from "./index.less";
import history from "./helpers/history";
import {Router, Route, Switch, Redirect, Link} from "react-router-dom";
import Hello from "./router/Hello";
import TodoList from "./router/TodoList";


const PrivateRoute = ({ component: Component , ...rest}) => {
    return (
         (
            
        )}/>
    );
}


ReactDom.render(
    
        

            

                
Homes
                
TodoList
            
            
                
                {/**/}
                
            
        
    ,
    document.getElementById("root")
);

...ES7語(yǔ)法報(bào)錯(cuò)

npm i -S babel-preset-stage-2

修改.babelrc

{
  "presets": ["es2015", "react", "stage-2"],
}

5.引入mobx狀態(tài)管理

npm i -S mobx mobx-react

使用裝飾器語(yǔ)法

修改tsconfig.json

"compilerOptions": {
   "target":"es2017",  //fix mobx.d.ts error
   "experimentalDecorators": true,
   "allowJs": true
}

npm i -D babel-plugin-transform-decorators-legacy

修改.babelrc

{
  "presets": ["es2015", "react", "stage-2"],
  "plugins": ["transform-decorators-legacy"]
}
