webpack打包動態鏈接庫DDLPlugin

動態鏈接庫

不重複打包某些不會變動的文件，加快我們的打包速度
使用webpack的DllPlugin和DllReferencePlugin插件

webpack.ddl.config.js

let path = require('path');
let webpack = require('webpack');

module.exports = {
    mode: 'development',
    entry: {
        react: ['react', 'react-dom']
    },
    output: {
        filename: '_dll_[name].js',
        path: path.resolve(__dirname, 'dist'),
        library: '_dll_[name]',
    },
    plugins: [
        new webpack.DllPlugin({
            name: '_dll_[name]',
            path: path.resolve(__dirname, 'dist', 'manifest.json'),
        })
    ]
};

webpack.config.js

let path = require('path');
let HtmlWebpackPlugin = require('html-webpack-plugin');
let webpack = require('webpack');
module.exports = {
    entry: './src/index.js',
    mode:'development',
    devServer: {
        port: 3000,
        open: true,
        contentBase: './dist',
    },
    module: {
        // noParse: /jquery/,  // 不去解析jquery中的依賴關係，
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                include: path.resolve('./src/'),
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: [

                            '@babel/preset-react',
                        ]
                    }
                }

            }
        ]
    },
    output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, 'dist')
    },
    plugins: [
        new webpack.DllReferencePlugin({
            manifest: path.resolve(__dirname, 'dist', 'manifest.json'),
        }),
        new webpack.IgnorePlugin(/\.\/locale/, /moment/),
        new HtmlWebpackPlugin({
            template: './public/index.html',
            filename: 'index.html',
        }),
    ]
