clean-webpack-plugin - 每次打包時清理上次打包生成的目錄

官網指南關于這個插件部分內容已經過時沒有更新，按照官網配置會出錯，所以參考github上這個插件文檔來配置， 文檔地址: https://github.com/johnagan/c...

html-webpack-plugin - 生成打包文件中的 index.html

yarn add clean-webpack-plugin html-webpack-plugin -D

config/webpack.common.js

        ...
        + const HtmlWebpackPlugin = require("html-webpack-plugin");
        + const { CleanWebpackPlugin } = require("clean-webpack-plugin");

        function webpackCommonConfigCreator(options){
            ...
            return {
                ...
                plugins: [
                    + new HtmlWebpackPlugin(),
                    + new CleanWebpackPlugin({
                    +     cleanOnceBeforeBuildPatterns: [path.resolve(process.cwd(), "build/"), path.resolve(process.cwd(), "dist/")]
                    + }),
                ]
            }
        }
        ...

src/index.js

        var ele = document.createElement("div");
        ele.innerHTML = "hello webpack";

        document.body.appendChild(ele);

yarn start， 效果：

yarn build, build目錄下生成index.html并且引入了bundle.js

接下來配置react

    yarn add react react-dom

    yarn add @babel/core @babel/cli @babel/preset-env -D
    yarn add @babel/preset-react -D
    yarn add babel-loader -D

config/webpack.common.js

        ...
        function webpackCommonConfigCreator(options){
            ...
            return {
                ...
                + module: {
                +     rules: [
                +         {
                +             test: /.(js|jsx)$/,
                +             include: path.resolve(__dirname, "../src"),
                +             use: [
                +                 {
                +                     loader: "babel-loader",
                +                     options: {
                +                         presets: ["@babel/preset-react"],
                +                     }
                +                 }
                +             ]
                +         }
                +     ]
                + },
                ...
            }
        }

src/index.js

        import React from "react";
        import ReactDom from "react-dom";
        import App from "./App.js";

        ReactDom.render(, document.getElementById("root"));

src/App.js

        import React from "react";

        function App(){
            return (
                

                    hello react
                
            )
        }

        export default App;

創建public/index.html

public/index.html

config/webpack.common.js

        ...
        function webpackCommonConfigCreator(options){
            ...
            return {
                ...
                plugins: [
                    - new HtmlWebpackPlugin(),
                    + new HtmlWebpackPlugin({
                    +     template: path.resolve(__dirname, "../public/index.html")
                    + }),
                    ...
                ]
            }
        }

開發模式下，改動代碼，瀏覽器將刷新頁面來更新改動，配置模塊熱替換，瀏覽器不刷新，而是通過dom操作來更新改動，對頻繁更新代碼的開發模式更加友好

    yarn add react-hot-loader -D

config/webpack.common.js

        ...
        function webpackCommonConfigCreator(options){
            ...
            return {
                ...
                module: {
                    rules: [
                        {
                            test: /.(js|jsx)$/,
                            include: path.resolve(__dirname, "../src"),
                            use: [
                                {
                                    loader: "babel-loader",
                                    options: {
                                        presets: ["@babel/preset-react"],
                                        + plugins: ["react-hot-loader/babel"],
                                    }
                                }
                            ]
                        }
                    ]
                },
                ...
            }
        }

src/App.js

        + import {hot} from "react-hot-loader/root";
        ...
        export default hot(App);

config/webpack.dev.js

        ...
        const config = {
            devServer: {
                contentBase: path.join(__dirname, "../dist"),
                + hot: true
            }
        }
        ...
