之前我有写过博文介绍过dva.js及其用法，dva.js固然是个非常优秀的框架，但是如果用dev-cli来创建的话就会默认绑定使用roadhog而不是webpack。鉴于roadhog的文档要明显少于webpack，如果能使用webpack+dvajs的话使用起来应该会轻松些。本文大致来介绍下dvajs+webpack3.11.0 开发环境的搭建过程。

首先先贴上package.json：

{
  "name": "dva-webpack-boilerplate",
  "version": "1.0.0",
  "description": "Boilerplate for Dvajs + React + Webpack project with JSX, ES6 and decorator compilation",
  "scripts": {
    "start": "webpack-dev-server --hot --open --port 11111 --config  config/webpack.dev.config.js",
    "build": "webpack --config config/webpack.prod.config.js"
  },
  "keywords": [
    "react",
    "reactjs",
    "boilerplate"
  ],
  "license": "MIT",
  "devDependencies": {
    "babel-core": "^6.9.1",
    "babel-loader": "^7.1.2",
    "babel-plugin-transform-decorators-legacy": "^1.3.4",
    "babel-plugin-transform-runtime": "^6.23.0",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-react": "^6.5.0",
    "babel-preset-stage-1": "^6.5.0",
    "copy-webpack-plugin": "^4.5.1",
    "css-loader": "^0.28.11",
    "extract-text-webpack-plugin": "^3.0.2",
    "html-webpack-plugin": "^3.2.0",
    "node-sass": "^4.9.0",
    "sass-loader": "^7.0.1",
    "style-loader": "^0.21.0",
    "uglifyjs-webpack-plugin": "^1.2.5",
    "url-loader": "^1.0.1",
    "webpack": "^3.11.0",
    "webpack-dev-server": "^2.11.2",
    "webpack-merge": "^4.1.2"
  },
  "dependencies": {
    "dva": "^2.2.3",
    "react": "^16.3.2",
    "react-dom": "^16.3.2"
  }
}

然后是.babelrc

{
  "presets": [
    "react",
    "es2015",
    "stage-1"
  ],
  "plugins": ["transform-decorators-legacy" ,"transform-runtime"]
}

项目根目录存放好这两个文件，再运行cnpm i ，环境搭建就算是完成了一半。

接下来是webpack的配置。为了区分开发环境与生产环境，将webpack.config.js分成了三个文件：webpack.base.config.js、webpack.dev.config.js、webpack.prod.config.js

webpack.base.config.js

var path = require('path');
var webpack = require('webpack');
module.exports = {
    devtool: '#source-map',
    entry: [
        './src/index'
    ],
    output: {
        path: path.join(__dirname, 'dist'),
        filename: 'build.js',
        publicPath: '/dist/'
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin(),
    ],
    resolve: {
        extensions: ['.js', '.jsx']
    },
    module: {
        rules: [
            {
                test: /\.jsx?$/,
                use: ['babel-loader'],
                include: path.join(process.cwd(), 'src')
            }, {
                test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
                loader: 'url-loader',
                options: {
                    limit: 10000,
                }
            },
            {
                test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
                loader: 'url-loader',
                options: {
                    limit: 10000,
                }
            },
            {
                test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
                loader: 'url-loader',
                options: {
                    limit: 10000,
                }
            }
        ]
    }
};

webpack.dev.config.js

const baseWebpackConfig = require('./webpack.base.config');
const merge = require('webpack-merge');
module.exports = merge(baseWebpackConfig, {
    // mode:"development"
    module: {
        rules: [
            {
                test: /\.scss$/, use: ['style-loader', 'css-loader', 'sass-loader']
            }]
    }
});

webpack.prod.config.js

const path = require('path');
const webpack = require('webpack');
const baseWebpackConfig = require('./webpack.base.config');
const merge = require('webpack-merge');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = merge(baseWebpackConfig, {
    output: {
        path: path.join(process.cwd(), 'dist'),
        filename: 'build.js',
    },
    // mode: "production",
    module:{
        rules: [
            {
                test: /\.scss$/,
                use: ExtractTextPlugin.extract({
                    fallback: 'style-loader',
                    use: ['css-loader', 'sass-loader']
                })
            }
        ]
    },
    plugins: [
        new webpack.DefinePlugin({
            'process.env': {
                'NODE_ENV': JSON.stringify('production')
            }
        }),
        new ExtractTextPlugin({
            filename: 'style.css'
        }),
        new UglifyJsPlugin({
            uglifyOptions: {
                compress: {
                    warnings: false
                }
            },
            parallel: true
        }),
        new HtmlWebpackPlugin({
            filename: path.join(process.cwd(), 'dist/index.html'),
            template: 'index-build.html',
            inject: false,
            minify: {
                removeComments: true,
                collapseWhitespace: true,
                removeAttributeQuotes: true
            },
            chunksSortMode: 'dependency'
        }),
        new webpack.HashedModuleIdsPlugin(),
        new CopyWebpackPlugin([
            {
                from: path.resolve(__dirname, '../static'),
                to: 'static',
                ignore: ['.*']
            }
        ]),
    ]
});

最终目录结构：

config存放三个webpack配置文件，dist存放生成出来的成品，static存放图片等静态资源。

index.html用于开发环境，index-build.html用于生产环境，方便配置cdn。

到此环境搭建完毕。
